Abstract

The paper introduces an approach to solve the problem of damping the electromechanical oscillations of conventional plant-photovoltaic generator hybrid system. The photovoltaic generator is coupled directly to the DC-link of AC-DC parallel connection to a large power system. The intermittent nature of the photovoltaic generator imposes an unpredictable characterization of negative load which affects the power system dynamic stability. The control process is actuated through a proportional-integral-derivative (PID) power system stabilizer (PSS) and PID-rectifier current regulator (RCR)
