Abstract

In distribution power generation, hybrid systems play an important role, mainly due its flexibility and reliability. This paper deals with the development of a control strategy for hybrid hydro-PV generation system employing a three-phase three-legs Split-Source Inverter (SSI) like a distribution synchronous static compensator (DSTATCOM). The SSI has the ability to feed ac loads with a boost characteristic. In addition, the proposed control strategy ensures regulation for balanced output ac voltages and load disturbance compensation of self excited induction generator (SEIG) based systems, providing the required active and reactive power. The modeling of the system and the design of the resonant controller are presented in detail. In addition, simulation results are presented to demonstrate the performance of the proposed control strategy.
