Development of Computational Technique for Better Utilization of Renewable Energy

Abstract:

The project illustrates an idea of connecting the photovoltaic systems with the Grid, GCPS. In this work, the photovoltaic source of generation, the PVG is connected to the main electric grid via two static electronic stages. The first stage contains a buck-boost dc-dc converter, insuring impedance adaptation between PVG and grid. This converter is controlled by the Fuzzy Sliding Mode controller, FSMC. The controller is used to track the dc reference voltage which is used to satisfy the main grid. The second stage is composed of a dc bus and a three-phase voltage inverter, which serves as an interface to the PVG and the grid utility. The inverter output is regulated by means of suitable filters to inject the high quality Photovoltaic, PV power into the grid. The GCPS has been implemented in the MATLAB. The performances of the fuzzy sliding controller are compared to the results obtained by a sliding mode controller. The satisfactory simulation results, reduces the phenomenon of chattering. The resulting waveforms indicate the robustness of control against variation of the load and the source voltage of the converter.
