Smart utilization of solar and wind power farm inverters as SSSC in grid connected renewable energy system

This paper presents the smart utilization of solar and wind farm inverters as Static Synchronous Series Compensator (SSSC) in grid integrated renewable power system. In this, the grid side voltage source converter of photovoltaic (PV) and wind power generation system can function as SSSC in addition to its basic operation of inverter as per the requirement of grid. Operation of these inverters as SSSC can provide real and reactive power compensation. It can be able to enhance the steady state power transfer limit of the line in case of increased load demand. Besides this, it can also be utilized as short circuit limiter and in mitigation of subsynchronous resonance and power oscillations. In this paper, MATLAB simulation is performed to realize the above mentioned capabilities of proposed system.
