Abstrakt: This paper deals with the development of a control strategy for stand-alone hybrid hydro-PV generation system employing a three-phase three-leg split-source inverter (SSI). The SSI merges the inversion and boost stages in one single power conversion system. In addition, the proposed control strategy ensures regulation for balanced output ac voltages, load disturbance rejection and harmonic compensation of self-excited induction generator (SEIG) as hydroelectric system, providing the required active and reactive power. Moreover, the integration of PV generation source in the microgrid system provides flexibility and reliability, enabling power flow management. The modeling of the system and the design of the resonant and proportional integral controllers are presented. Furthermore, simulation and experimental results are presented to demonstrate the performance of the proposed control strategy. [ABSTRACT FROM AUTHOR]
