Abstract

As the conventional power plants are being replaced by renewable energy sources like wind and solar, large power plants based upon the renewable energy sources are expected to provide ancillary services and functionalities like voltage and frequency regulation, and to mitigate the variability of power supply. Thus, there is a need for the control of both active and reactive power generation from the plant. Wind power plants have limited controllability of active power due to their dependency upon the instantaneous wind conditions; while the reactive power should be locally compensated at the Point of Connection (PoC). This paper describes the application of a modular multilevel converter (MMC) static compensator (STATCOM) with Battery Energy Storage System (BESS) as an integrated solution to these requirements. Simulation results demonstrate the inertial as well as fast droop response for frequency control, while the voltage regulation is relatively slow process.
