Passive harmonic filtering is used in this work to improve the harmonic-constrained hosting capacity (HC-HC) of inverter-based distributed generation (DG) systems under non-sinusoidal grid conditions. The optimum parameters of a C-type passive filter (CTPF) along with the rating of the DG system are concurrently fixed. The best possible HC of the distorted grid for DG is realized while keeping overall filter cost (FC) suffered at the lowest. A best-of-breed solution is attained making use of the newly proposed multi-objective Pareto-based bat algorithm (pb-MOBA). The formulated problem of multi-objective optimization (MOO) is dealt with under a number of system performance indices (PIs) constraints such as individual as well as total harmonic distortion (THD) in the line current and the point of common coupling's (PCC) voltage, distribution line ampacity under harmonic current overloading, steady-state voltage profile, load power factor (PF), and so on and a handful that is linked to the passive power filter (PPF) itself. The Pareto optimal front is produced using the MOBA extension, and the trade-off between the objectives is examined. The efficiency and accuracy of pb-MOBA, in dealing with the designated MOO problem, is confirmed by making a comparison of the acquired solution and three computed PIs viz. diversity metric (DM), generational distance (GD), and convergence metric (CM) with those achieved by Multi-objective Pareto-based PSO (pb-MOPSO), Non-dominated Sorting Genetic Algorithm (NSGA), Multi-objective Evolutionary Algorithm based on Decomposition (MOEA/D), and the Strength Pareto Evolutionary Algorithm (SPEA). The Monte Carlo approach provides a true Pareto front (TPF) that meets the requirement. Also as additional analysis, the effects of utility-side background voltage distortion (BVD) plus load-side’s nonlinearity level (NLL) on the performance of filter are explored. The results of the simulation achieved with different BVD and NLL levels demonstrate that the presence of distortion in the background is helpful from the filter's cost perspective. From the enhanced HC perspective though both are seen leaving negative impact nonetheless BVD is proven to be more harmful than NLL on the load side.

Increasing the penetration level (PL) of renewable energy in the distribution power grids has the potential of fulfilling growing energy demands and curtailing fossil fuel usage along with its economic and technical benefits. Nevertheless, the quantity of electricity supplied to customers cannot be permitted to take precedence over its quality. This is because the high penetration of the renewable-based power generation comes at the cost of power quality deterioration, especially at the point of common coupling (PCC), owing to nonlinear characteristics of renewable-based distributed generation (DG) systems and pre-contamination of modern distribution grids. So, the role of power quality (PQ) improvement technologies inevitably comes into the picture when the required level of renewable energy penetration is constrained by any of the grid PQ performance indices. Passive power filters (PPFs) have proven to be a very successful solution for increasing the harmonic-constrained penetration level (HC-PL) of renewable energy in power systems. However, there is a scarcity of information on how to choose between various passive filters to meet high penetration objective. The purpose of this paper is to look into the problem of filter type selection. The designing of different PPF types is formulated as an optimization problem with an objective to enhance the penetration of a renewable DG system in a distorted distribution power grid and solved by the firefly algorithm (FA). A comprehensive assessment of common PPF types, in terms of effectiveness in increasing renewable energy penetration in a harmonically polluted distribution grid along with their economic aspects, is performed. The simulation results show that the filters under consideration can be ranked from best to worst as composite type, third-order damped, C-type, second-order damped and single-tuned (ST) ones in terms of their performance on the percentage penetration level enhancement of renewable energy. While in terms of per-unit cost, the highest percentage enhancement in penetration is obtained by the ST filter.

Electric vehicles (EVs) have remarkably emerged as an alternative for internal combustion engines. With high penetration levels of the EVs, its addition to the existing distribution line infrastructure affects the power quality and grid stability. Additionally, EV charging loads are characteristically different as they are mobile compared to other fixed node-connected loads. Proposing solutions without considering these factors may result in grid congestion and subsequent over/under compensations. Another emerging dynamics co-occurring in the distribution system is high penetration levels of renewable energy in the utility grid. Although these dynamics pose challenges in stable grid operation, it also gives opportunities for solving some of the grid integration issues of EV loads. Thus, the effect of adding EV charging load to the existing low voltage distribution system must be analyzed by considering different criteria such as grid impact with different EV chargers, mobile nature of EV load, power quality, voltage profile, and spread/peak demand of load curve. This paper presents a detailed report on the impact analysis of EV integration on the component and system levels. For analyzing the effect on power quality (component level), grid pollution contributed by EV chargers along with possible solutions is elucidated. Detailed discussion on the significance of EV load location, existing load distribution, and nature of EV charging load distribution is presented by considering different feeders and different load curves. These discussions are supported with simulated case studies followed by a review of existing literature for enhanced understanding. Finally, techniques employed to effectively model the mobile nature of EV load and distributed EVs potential to provide ancillary solutions are also explained.

Thesis
Energy should, be sustainable and never affect human health either during generation or any other stages. Within present trends to develop energy scenarios with diminishing use of fossil fuels, nuclear power, etc. it seems difficult to meet an increasing need for energy. Incorporation of renewable energy sources within the energy sector could mitigate future energy crises in a sustainable way. Bangladesh has great renewable energy prospects when compared with other south-Asian countries. Severe energy crises such as generation not being able to keep up with demand result in outages, load-shedding, and even blackouts. This problem could be reduced by introducing renewable energy resources at a large scale within our power sector. Renewable energy sources are increasingly used due to their availability and it has a little negative impact on the environment. But the renewable energy is still young as technology and many of its components are still in their preliminary stages. Multilevel inverters are one of the great solutions that are proposed to satisfy the demand for high-power applications and the significant integration of renewable energy. The conversion process from DC to AC must be done at high efficiency to decrease the energy loss and to ensure the electric grid power quality. The Total Harmonic Distortion (THD) is the most important feature that indicates the efficiency of the conversion process. This thesis presents the design, simulation and various analyses on multilevel inverters. The inverter is then implemented in a grid-tied PV system to observe the inverter's effect in three-phase. Some additional tools other than Simulink were utilized to design the grid-tied system for a university campus and run analysis. Electrical, mechanical, and economic analysis is conducted with the assistance of some fixed assumptions within those tools. The proposed system yielded a THD of 4.63% in a single phase. The net renewable fraction achievable by the system was 3.03% and an optimized system with multiple such clusters yielded a 45.2% renewable fraction of the total electrical energy consumed. This dissertation would aid our peers to explore this frontier of distributed generation by providing THD values achievable from multilevel cascaded H-bridge inverters applying various control techniques, and also encourage them to study the available professional PV design tools.
... On the other hand, current THD limits vary based on the short circuit strength of the system they are injected into [163]. This thesis considers a THDi of 7%, recommended by the machine manufacturer. ...

The electrification of means of transport is a challenging reality that has taken over the scene over the years. The socio-environmental impact of burning fossil fuels and their future scarcity guided sustainable and versatile efforts of energy consumption development. The aerospace domain has set ambitious goals regarding gas emissions limitation, leading to new concepts and system architectures in several sectors. The replacement of heavy systems, such as mechanical, pneumatic, and hydraulic systems, reduces aircraft weight and fuel consumption with their electrical equivalents. Several projects have emerged in the last decades aiming to replace these systems using new technologies.This thesis presents an optimized design of a DC – AC converter (filters included) with gravimetric power density superior to 8 kW/kg and higher efficiency than 98.5 % for a 70 kVA MEA power drive system. Among different inverter topologies and semiconductors technologies, a 7-level flying capacitor three-phase inverter, composed of three paralleled legs of 3-level flying capacitor topology per phase with 4 GaNs in parallel per switch, was chosen to be built. The prototype presented around 14 liters and 10.04 kg (it comprises filters, metallic structure, and control board). The measured weight is less than 4 % superior considering the solution proposed in simulation, which corroborates the precision of the models used in the optimization procedure. A traditional 2-level converter using 1200 V for the same operating conditions shall be 74 % heavier than the 7-level inverter, with a power density 43.4 % smaller than the multilevel topology. On three-level flying capacitor leg with 4 GaNs in parallel per switch was extensively explored, and the solution reached almost 99.2 % of measured efficiency, for 38 A / 5.8 kW at the output of the converter (DC-DC Buck test) and 98.8 % in the monophase inverter test (42 A / 6.6 kW at the output of the converter) , both at 40 kHz with an RL load (resistor + inductor). The experimental verification of the entire converter led to 98.6 % efficiency at 24.6 kVA (flf = 240 Hz, fsw = 40 kHz and Mi = 0.76). Due to circulating currents between paralleled legs, inverter safe operation was limited to 500 V/38 kVA/87 A (70 kVA/130 A nominal operation) with open-loop control. Regarding EMI modeling, this thesis proposed a generic model for multilevel converter equivalent circuit with good correspondence until 5 to 6 MHz (supported by experimental results) and can assist predictive design of EMI filter.
... For these reasons, grid-filters are often applied to high-power converters in the form of LCL-filters [27] and, according to the IEEE 519 standard, the emitted current harmonics must be limited. For instance, as described in the IEEE 519 [28,29], the current THD of power generating converter units must be constrained to about 5 %, considering the first 50 harmonic current components. It should be noted, within the remainder of this paper, the expression THD is used for the current THD, unless otherwise specified. ...

Modular Multilevel Converters (MMC) with integrated battery packs have been proven to be a viable option for various electric power applications. In novel applications, fully charged battery packs are used to form flexible output voltage waveforms. Nonetheless, the charging of the batteries after the actual usage has previously not been described for MMC based inverters with integrated battery packs. This paper presents an approach of power grid compliant electric vehicle battery charging for Battery Modular Multilevel Management (BM3) converter systems with three-switch modules using a PR controller when directly connected to the AC grid. By using such a system, the conventional battery electric vehicle’s on-board charger and any additional battery balancing circuitry become obsolete. It is demonstrated, that the analyzed approach is able to charge the battery modules with a current total harmonic distortion of less than 5% at any charging power level without the usage of a dedicated grid filter. Furthermore, the power factor angle can be freely adjusted.

Increased green energy presence in distribution power networks has the ability to resolve rising energy demands while also reducing fossil fuel consumption, as well as providing economic and technical merits. However, the quantity of power delivered to customers cannot be allowed to take precedence over the quality of that electricity. This is because the high penetration of the renewable-based power generation comes at the cost of power quality deterioration, especially at the point of common coupling (PCC), owing to nonlinear characteristics of renewable-based distributed generation (DG) systems and pre-contamination of modern distribution grids. So, the function of power quality (PQ) improvement technologies unavoidably comes into the picture when the hosting capacity (HC) of renewable energy systems is constrained by any of the grid PQ performance indices. This paper investigates the application of a hybrid active power filter (HAPF) to improve the harmonic-constrained hosting capacity (HC-HC) of renewable DG systems in harmonically polluted distribution systems. A shunt type HAPF designing with an objective of achieving maximum HC-HC is considered as an optimization problem and solved by the firefly algorithm (FA) under several constraints the system particularly related to individual and total harmonic distortion (THD) limits in line current and voltage at PCC, harmonic currents overloading of distribution feeder. Aside from harmonics, constraints related with voltage rise and drop limits, as well as power factor (PF), are also taken into account to ensure the optimal use of the HAPF as a compensator. The proposed HAPF-based HC-HC improvement approach's findings and efficacy are compared to those acquired from one of the literature's recently proposed techniques. Besides, the study is extended for HC-HC enhancement by HAPF, under changing utility-side's background voltage distortion (BVD) and load-side’s nonlinearity level (NLL) conditions. The performed extended investigation of the system shows that HC-HC enhancing the effectiveness of the proposed approach is rather less susceptible to utility or customer side contribution to background distortion at the PCC.
... The standard limits of the total harmonic distortion (THD) in any power system are listed in (ANSI/IEEE 519-1992) standard lists [25,26]. Thus, the analysis of the harmonics of the system and the system installation should meet standard (IEEE 519-1992) to limit the THD [27]. ...

Power quality can have a large detrimental effect on industrial processes and the commercial sector. Thus, this paper proposes a new technique to improve the power quality of electric power systems. This technique relies on auto-adjusting of the blade angle to mitigate the harmonics in wind generator active power. A new adaptive PI blade-angle controller is applied in this technique to reduce the total harmonic distortion (THD) of the output power. The parameters of the adaptive PI controller are initialized by using the Harmony Search algorithm (HSA), hybrid Harmony Search optimization and Equilibrium optimization (EO), and hybrid Harmony Search optimization and Teaching learning-based optimization (TLBO). The execution of the optimization algorithms relies mainly on the optimization objective function. Two optimization objective functions are mathematically modeled and compared to enhance the power quality. The first one is to minimize the sum square of error, while the second objective is to minimize the THD. Many case studies are applied with various wind-speed profiles under normal and faulty conditions. Results show the superiority of HSA hybrid EO algorithm with the second objective functions through reducing the harmonics and enhancing the power quality. Moreover, laboratory studies are applied to investigate the effect of the blade-angle variations on the extracted active power.

Nowadays, the electric power distribution system is undergoing a transformation. The new face of the electrical grid of the future is composed of digital technologies , renewable sources and intelligent grids of distributed generation. As we move towards the electrical grid of the future, microgrids and distributed generation systems become more important, since they are able to unify small-scale and flexible generation to clean energy and intelligent controls. The microgrids play an important role in marking electrical grids more robust in the face of disturbances, increasing their resilience. Although the microgrid concept continues in discussion in technical circles, it can be defined as an aggregation of electrical elements in low generation voltage, storage and loads (users) which are grouped in a certain bounded geographical area. The issues of a microgrid integrated with energy storage technologies has gained increasing interest and popularity worldwide as these technologies provide the reliability and availability that are required for proper operation in the system. Actual studies show that the implementation of energy storage technologies in a microgrid improves transients, capacity, increases instantaneous power and allows the introduction of renewable energy systems. However, there are still certain unsolved problems in power quality terms. This article clearly describes those problems generated by each storage technology foe microgrids applications. All the ideas in this review contribute significantly to the growing effort towards developing a cost-effective and efficient energy storage technology model with a long-life cycle for sustainable implementation in microgrids.

A single-phase, single-stage, differential boost inverter comprises two independently-controlled boost DC-DC converters, with the load connected between their outputs. The net voltage on the load is sinusoidal and has a controllable frequency and magnitude that is larger than that of the DC source. The present work first derives steady-state and small-signal models of the inverter with parasitic elements. The results obtained from the line-to-output transfer function, control-to-output transfer function, open-loop input impedance, and open-loop output impedance models are compared with that of the ones obtained from the experimental testbed. Using the new models, a voltage mode controller is designed in the synchronous reference frame. The regulator design is explored through the use of an example. The results are verified against the small-signal model, then PLECS simulations, and finally a laboratory experiment. The results indicate excellent agreement between the model and experiment during transients in voltage reference, input source voltage, and output load. A sensitivity analysis is performed based on the inverter model considering the parameter variation. Finally, loss and efficiency estimations are provided in this work.
