Demand response (DR) improves grid stability by enabling communication between the grid and consumers. However, managing residential load variability during DR events is challenging, especially in smart grids with renewable energy sources like wind and photovoltaic systems. This study aims to develop an advanced demand response scheduling strategy...

The escalating global energy demand is spurring a transition towards renewable energy sources (RES), with distributed generation (DG) units such as photovoltaic (PV) and wind energy conversion systems (WECS) playing pivotal roles in microgrid technology. This study proposes an innovative approach integrating an Improved Z Source Converter with a Bi...

Multilevel inverters (MLIs) have become a favoured option for medium voltage and high power DC to AC conversion applications to assure high power level cascade type inverter which accepts multiple/single DC sources and offers combined AC output for appropriate voltage and frequency. MLIs provide various benefits over two-level inverters, including...

Electrical power systems are accessible in renewable energy systems, and hybrid battery systems or energy storage systems (ESS) are capable of delivering uninterruptible power to the demand even if faults occur. Additionally, the energy storage device increases system dynamics during power fluctuations. A photovoltaic (PV) battery hybrid system wit...

Electric charge-related electrical control of ferromagnetic semiconductors. In this case, the mercury charger produces a ferromagnetic bond. The limited power Hc that causes reloading can be limited by changing the back-to-back of the car using the electric field of the channel structure. The reverse of the electromagnetic rear as electromagnetic w...

The line frequency transformer and voltage regulation is connected with bidirectional micro grid. In hybrid micro grid major problem is occupy more space and more is major problem. so, these results to overcome in this paper to propose a BRDT. For design of BRDT is very simple loop and it is 50% of duty ratio better than phase shift. In BRDT consis...

p>Brushless DC motors (BLDC) are predominantly used these days due to its meritorious advantages over conventional motors. The paper presents PV fed BLDC speeds control system. A closed-loop interleaved boost converter increases the voltage from PV system to required level. Converter for BLDC operates at fundamental switching frequency which reduce...

This paper presents the control of a multilevel inverter supplied by a Photovoltaic (PV) panel and a batteries bank. It is well known that the power quality of multilevel inverter signals depends on their number of levels. However, the question that arises is whether there is a limit beyond which it is not necessary to increase the number of level....

This paper presents a comparative analysis of three control algorithms for a wind turbine generator using a variable speed permanent magnet synchronous generator (PMSG). The design methodologies of the conventional PI based controller, the Taylor series expansion linear approximation based (TSLA-based) controller and the feedback linearization base...

This paper presents the performance of Brushless DC (BLDC) Motor drive with only one positioning sensor instead of three conventional sensors. The three sensor units are replaced with a single stator current sensor unit in DC bus which further reduces the cost increasing the reliability of the drive system. Using a single sensor in stator requires...

As of late, multilevel inverters (MLI) have picked up much consideration in the application regions of medium voltage and high power owing to their different favorable circumstances, for example, lower regular mode voltage, lower voltage weight on force switches, lower dv/dt degree to supply lower consonant substance in yield voltage and current. L...

The present study deals with the effect of hydrodynamic interactions of the neighboring particles on the hydrodynamic permeability of a bed of porous particles. Two different hydrodynamic models namely cell model and effective medium model are discussed. Cell model is one of the most effective models to deal with the flow through bed of particles....
