| Abstract | In this paper, the Authors present a voltage control for a hybrid photovoltaic-diesel system. The considered system is composed of a DC generator, a photovoltaic array and a supervisor associated to an isolated DC load composed of a DC motor and a hydraulic centrifuge pump. The diesel motor is used to drive the DC generator in order to feed the load when the PV array required insulation is down. The load receives the input power from the photovoltaic array through a synchronous boost converter and a DC bus when the insulation is sufficient; else it receives the required active power from the DC generator. A modeling study was performed for the proposed Hybrid system components. Modelling of the PV array, DC Generator, Diesel engine, and the synchronous boost converter were established and used in the control proposed scheme. An extensive simulation work was performed to extract the significant results. To show up the high system performances, presented results are discussed and prove how the proposed methodology is an efficient hybrid photovoltaic diesel control procedure. |
