Stability of Grid with the Penetration of Solar PV based Generation in Power Systems

High PV penetration levels have distinct characteristics which are different from conventional generation resources. That is why, it affects the steady state as well as transient stability of the systems. A significant amount of power generation may be replaced with the power generated by the distributed PV resources. Nowadays, it is in vogue to integrate renewable source of power with conventional power system. The conventional Diesel Generator with high penetration of PV based power generation is controlled by P-Q method and Fuzzy Logic control. Conventional Diesel Generator is chosen as Base load generation. Boost Converter amplifies the power output of PV module. THD component is reduced by Filter. The breakers with specified timing of switching are used to connect the generators for grid integration. On and off switching of the base load generator with the Grid having power generation of PV module and its impacts are analyzed with the help of specified timing.Coordinated control of the integrated power system is successfully done with the THD components within international parameters.
