Contribution to the improvement of power quality using multi hybrid model based wind-shunt FACTS

In recent years renewable energy and FACTS devices are two technologies integrated widely in the electricity market. This paper presents a coordinated model based wind generator and dynamic shunt FACTS devices to improve the power system operation and control. Choosing the type of FACTS devices and deciding the installation location and control of multi shunt FACTS coordinated with multi wind source is a vital research area. A simple algorithm based differential evolution (DE) proposed to find the optimal reactive power exchanged between shunt FACTS devices and the network in the presence of multi wind source. The system loadability and loss minimization are considered as a measure of power system quality. The proposed methodology is verified on many practical electrical network at normal and abnormal conditions (sever loading conditions, contingency). Simulation results show that the optimal coordination operating points of shunt FACTS (STATCOM) device and wind source under various conditions of power system enhance the power system reliability.
