Application of integrated wind energy conversion system (WECS) and photovoltaic (PV) solar farm as Statcom to regulate grid voltage during night time

This paper presents the concept of utilizing photovoltaic (PV) solar farm (SF) as flexible ac transmission system controller-static synchronous compensator, to regulate the point of common coupling voltage during night time when the SF is not producing any active power. The proposed control will enable increased connections of WECS to the grid. MATLAB/Simulink based simulation results are presented for validation of the system.
