Performance Enhancement of Hybrid Solar PV-Wind System Based on Fuzzy Power Management Strategy: A Case Study

Abstract

A Standalone hybrid power generated system based on renewable energy systems such as photovoltaic solar (PV) system and PMSG wind turbines (WT) generators are coupled via DC-DC converters to satisfied electric and hydraulic network branch. The electric system branch devises in load as consumers side and the battery bank storage as the second side, the hydraulic system side made of one 5HP motor-pumps installed to meet the freshwater and satisfy consumer demand of a small isolated community. This part of the study describes the importance of binomial Power/Water to manage power flows optimization. For this and other reasons, a new strategy energy Management based on Fuzzy Logic is proposed and developed in this paper. A reliable simulator model of the proposed PV-Wind hybrid system has been introduced and tested via the SIMULINK-MATLAB environment. To extract a real scenario predicted, a group of tests is carried out with real data using meteorological data detected in Adrar region and compared with the practical load demand profile estimated. The simulation shows that the “coupled strategy” clearly outperforms the classical management strategies.
