This paper develops an energy management approach for a multi-microgrid (MMG) taking into account multiple objectives involving plug-in electric vehicle (PEV), photovoltaic (PV) power, and a distribution static compensator (DSTATCOM) to improve power provision sharing. In the proposed approach, there is a pool of fuzzy microgrids granules that they compete with each other to prolong their lives...

With countries moving toward renewable energy sources (RES), the need for dispatchability and storage solutions has become more prevalent. The uncertainty associated with wind turbine (WT) units photovoltaic (PV) systems further complex a system high level of intermittency. This work addresses this problem by proposing an operational planning approach to determine optimal allocation WT units, P...

Devolution of the power grid into smart was necessitated by proliferation sensitive load profiles system, as well incessant environmental challenges. These two factors culminated aggravated disturbances that cause serious havoc along entire system structure. The traditional proportional-plus-integral-plus-derivative (PID) solution offered distribution synchronous compensator (DSTATCOM) could no...

A static synchronous compensator (STATCOM) is generally used to regulate voltage and improve transient stability in transmission and distribution networks. This is achieved by controlling reactive power exchange between STATCOM and the grid. Unbalanced sags are the most common type of voltage sags in distribution networks. A static synchronous compensator (STATCOM) is generally used to maintain...

Hybrid <span>electric power generation and its integration with the grid to supply consumer demand is main focus of this paper. The use nonlinear load advanced electronic equipment-based devices at end introduces quality issues in system network terms voltage current. This paper explains design a control algorithm for unified conditioner used mitigating both current-based issues. dynamic ...

The Static Synchronous Compensators (STATCOMs) have been recoginzed as the most effective solution for dynamic reactive power compensation, voltage stability enhancement and subsynchronous resonance damping purposes in the electric power systems. The STATCOMs in the distribution utilites (DSTATCOMs) are increasingly investigated for dynamic reactive power compensation and power quality improvem...

This paper demonstrates a perfect controlled DSTATCOM model with a small isolated distribution system to improve power quality of the system in which a linear/nonlinear three-phase load is fed by a small alternator. A hysteresis rule based carrier-less PWM current controller is used to control the DSTATCOM. Three leg IGBT based PWM-VSI is used as VSC with a capacitor in its parallel working as ...

Electric power systems are among the greatest achievements of the last century. Today, important issues, such as an ever-increasing demand, the flexible and reliable integration of distributed generation or a growth in disturbing loads, must be borne in mind. In this context, smart grids play a key role, allowing better efficiency of power systems. Power electronics provides solutions to the af...

This paper presents a new method which applies the application of Genetic Algorithm as meta-heuristic optimization method for power system problems in distribution substations. With increase in load, any power system model suffers from disturbances. These disturbances effect the overall stability of the system. Criterias like voltage profile, power flows, losses tell us about the state of the s...
