    ABSTRACT: Electrical power quality has been an important and growing problem because of the proliferation of nonlinear loads such as power electronic converters in typical power distribution systems in recent years. Particularly, voltage harmonics and power distribution equipment problems result from current harmonics produced by nonlinear loads. The Electronic equipment like, computers, battery chargers, electronic ballasts, variable frequency drives, and switch mode power supplies, generate perilous harmonics and cause enormous economic loss every year. Problems caused by power quality have great adverse economic impact on the utilities and customers. Due to that both power suppliers and power consumers are concerned about the power quality problems and compensation techniques. Power quality has become more and more serious with each passing day. As a result active power filter gains much more attention due to excellent harmonic and reactive power compensation in two-wire (single phase), three-wire (three-phase without neutral), and four-wire (three-phase with neutral) ac power networks with nonlinear loads. However, this is still a technology under development, and many new contributions and new control topologies have been reported in the last few years. It is aimed at providing a broad perspective on the status of APF technology to the researchers and application engineers dealing with power quality issues.

    ABSTRACT: High-voltage earthing system design is required to ensure safety compliance and adequate operation of the high-voltage infrastructures. The transmission lines form a solid part of the high-voltage infrastructure. The underground to overhead (UGOH) pole earth grid is one of the main challenges when it comes to transmission line earthing system design. To ensure safety compliance at low cost, counterpoise earthing is used at the UGOH pole for the underground lines. The counterpoise aids in lowering the UGOH pole earth grid resistance. This paper addresses the counterpoise analysis as currently being studied. Furthermore, it introduces the counterpoise mutual voltage between the faulted phase and the counterpoise and its impact at the UGOH pole earth potential rise. Case study is included

    ABSTRACT: This paper presents a generalized formulation of Demand Response (DR) under deregulated electricity markets. The problem is scheduling and controls the consumption of electrical loads according to the market price to minimize the energy cost over a day. Taking into account the modeling of customers’ comfort (i.e., preference), the formulation can be applied to various types of loads including what was traditionally classified as critical loads (e.g., air conditioning, lights). The proposed DR scheme is based on Dynamic Programming (DP) framework and solved by DP backward algorithm in which the stochastic optimization is used to treat the uncertainty, if any occurred in the problem. The proposed formulation is examined with the DR problem of different loads, including Heat Ventilation and Air Conditioning (HVAC), Electric Vehicles (EVs) and a newly DR on the water supply systems of commercial buildings. The result of simulation shows significant saving can be achieved in comparison with their traditional (On/Off) scheme.

    ABSTRACT: A blackout can take place in entire power system or a part of the system due to extreme voltage instability (voltage collapse) that can appear abruptly. Instability prediction and continuous monitoring of the power system performance is, therefore, known exigent. This paper is conducted with a broad overview of the voltage stability indices, which are previously studied in the literature, and have the same foundation during their formulation. Afterward, an improved voltage stability indicator is introduced as a result of the multi-criteria integration and enhancement of the original indices by employing linear algebra methods. It is found that the proposed algorithm can overcome on the probable limitations from calculating point view. Then comparative analysis of the indices is presented in order to reach a unique consensus about the typical techniques of modal analysis (sensitivity, eigenvalue, right eigenvectors, and bus participation factor) as a precise algorithm. Finally, the IEEE 14-bus, and 30-bus test systems are selected to verify the algorithm, and compare the performance of the improved indicator approach with the existing indices.

    ABSTRACT: High-voltage infrastructure upgrade is expending due to the growth in populations. To save on easement cost and to reduce the environmental impact of these projects, HV transmission lines occupy the same easement as pipelines in many cases. This joint easement introduces the AC interference between transmission lines and pipelines. The induced voltage can reach a limit which will jeopardize the human safety. The cited research studies the induced voltage under the presence of the overhead earth wire (OHEW) using the shielding factor. The work in this paper studies the induced voltage using the OHEW section current along with the superposition theorem. The simulations are compared to the existing research methods. The case study along with the theoretical study discusses the advance accuracy of the proposed method over the existing shield factor used in the presence research. Furthermore, they introduce the effective length along with the effective shielding factor, which aids in computing the additional effect that the OHEW has on the induced voltage

    ABSTRACT: This paper proposes a synchrophasors-assisted intelligent relaying scheme for transmission lines compensated by Unified Power Flow Controller (UPFC). The algorithm uses a new relaying signal termed as imaginary part of integrated impedance (IPII). The synchronized phasor measurements at both ends of the transmission line are used to extract voltage and current phasors from instantaneous voltage and current signals. The voltage and current phasors are utilized to derive IPII of each phase. Further, IPII of each phase is used as input to a data-mining model termed as decision tree (DT) which provides the final relaying decision. The proposed algorithm is validated on real-time digital simulator (RTDS) platform, and the results obtained indicate that the proposed scheme is both dependable and secure in protecting transmission system compensated by UPFC.

    ABSTRACT: This paper proposes a minimal spanning tree (MST) algorithm to solve the networks’ reconfiguration problem in radial distribution systems (RDS). The paper focuses on power losses’ reduction by selecting the best radial configuration. The reconfiguration problem is a non-differentiable and highly combinatorial optimization problem. The proposed methodology is a deterministic Kruskal’s algorithm based on graph theory, which is appropriate for this application generating only a feasible radial topology. The proposed MST algorithm has been tested on an actual RDS, which has been split into subsystems.

    ABSTRACT: This paper presents a new implementation of a parameter adaptive PID-type fuzzy controller (PAPIDfc) for a grid-supporting inverter of battery to alleviate frequency fluctuations in a wind-diesel power system. A variable speed wind turbine that drives a permanent magnet synchronous generator is assumed for demonstrations. The PAPIDfc controller is built from a set of control rules that adopts the droop method and uses only locally measurable frequency signal. The output control signal is determined from the knowledge base and the fuzzy inference. The input-derivative gain and the output-integral gain of the PAPIDfc are tuned online. To ensure safe battery operating limits, we also propose a protection scheme called intelligent battery protection (IBP). Several simulation experiments are performed by using MATLAB®/SimPowersystems™. Next, to verify the scheme’s effectiveness, the simulation results are compared with the results of conventional controllers. The results demonstrate the effectiveness of the PAPIDfc scheme to control a grid-supporting inverter of the battery in the reduction of frequency fluctuations.

    ABSTRACT: Dynamic economic emission dispatch is an important optimization task in fossil fuel-based power plant operation for allocating generation among the committed units with predicted load demands over a certain period of time such that fuel cost and emission level are optimized simultaneously. It is a highly constrained dynamic multi-objective optimization problem involving conflicting objectives. This paper proposes multi-objective differential evolution for dynamic economic emission dispatch problem. Numerical results for a sample test system have been presented to demonstrate the performance of the proposed algorithm. The results obtained from the proposed algorithm are compared with those obtained from nondominated sorting genetic algorithm-II (NSGA-II).

    ABSTRACT: In the smart grid paradigm, the reactive power control of distributed energy resources (DERs) plays a key role improving the voltage profile in the distribution systems. This topic has been addressed by previous papers in which the Optimal Set-Point Design (OSPD) of DER reactive control, based on a decentralized approach, has been developed. The OSPD determines the set point of a reactive power closed-loop regulation scheme according to an optimization strategy. After briefly recalling the OSPD procedure, the article presents validation studies aiming at testing the effectiveness of the OSPD. The validation is based on a hardware-in-the-loop realtime simulation facility. In particular, an experimental setup has been arranged and presented, in which the system is simulated using the real-time digital simulator (RTDS), while the OSPD has been implemented on a PC in the LabView environment. The OSPD has been developed by considering two different optimization objectives, namely the feeder voltage profile optimization and the distribution losses minimization. The achieved results are then presented and also compared with the ones obtained a classical regulation scheme.

    ABSTRACT: In this paper, shoot-through current elimination DC-AC converter circuit has been presented with the application of active power filter (APF). The intuitive analysis of the shoot-through in the conventional DC-AC converter has been reported first. Interleaved buck (IB) converter is adopted to eliminate the shoot-through current, thereby increasing the reliability of the interleaved buck-based active power filter (IB-APF). The 3-phase 4-wire IB-APF eliminates the current harmonics produced by the load just as a conventional one does and are innately immune to "shoot-through" phenomenon, with the elimination of special protection features required in conventional inverter circuits. A comparison has been made about the compensation capabilities of the IB-APF with the PI and fuzzy logic controller (FLC) used by id-i q control strategy under different supply voltage conditions. The id-iq control strategy used for extracting the three-phase reference current for IB-APF, evaluating their performance here in MATLAB/Simulink environment and also implemented using real-time digital simulator hardware (OPAL-RT hardware). The RTDS result verifies that the total harmonic distortion percentage of the source current can be reduced below 5% according to IEEE-519 standard recommendations on harmonic limits.

    ABSTRACT: This article deals with automatic generation control of a multi-area interconnected thermal system in different modes using intelligent integral and proportional-integral controllers. Appropriate generation rate constraint has been considered for the thermal generation plants. The two cumulated thermal areas are considered with reheat turbines. Performances of reheat turbine on dynamic responses have been investigated. Further, selection of suitable integral and proportional-integral controllers has been investigated with a minority charge carrier inspired algorithm. Cumulative system performance is examined considering with different load perturbation in both cumulative thermal areas. Further, system is investigated with different area control errors, and results are explored.

    ABSTRACT: This article presents a control method for output power smoothing of a wind energy conversion system (WECS) with a permanent magnet synchronous generator (PMSG) using the inertia of wind turbine and the pitch control. The WECS used in this article adopts an AC–DC–AC converter system. The generator-side converter controls the torque of the PMSG, while the grid-side inverter controls the DC-link and grid voltages. For the generator-side converter, the torque command is determined by using the fuzzy logic. The inputs of the fuzzy logic are the operating point of the rotational speed of the PMSG and the difference between the wind turbine torque and the generator torque. By means of the proposed method, the generator torque is smoothed, and the kinetic energy stored by the inertia of the wind turbine can be utilized to smooth the output power fluctuations of the PMSG. In addition, the wind turbines shaft stress is mitigated compared to a conventional maximum power point tracking control. Effectiveness of the proposed method is verified by the numerical simulations.

    ABSTRACT: New high-voltage (HV) substations are fed by transmission lines. The position of these lines necessitates earthing design to ensure safety compliance of the system. Conductive structures such as steel or concrete poles are widely used in HV transmission mains. The earth potential rise (EPR) generated by a fault at the substation could result in an unsafe condition. This article discusses EPR based on substation fault. The pole EPR assessment under substation fault is assessed with and without mutual impedance consideration. Split factor determination with and without the mutual impedance of the line is also discussed. Furthermore, a simplified formula to compute the pole grid current under substation fault is included. Also, it includes the introduction of the n factor which determines the number of poles that required earthing assessments under substation fault. A case study is shown.
