Abstract
En 中文
The aim of this paper is to develop and simulate supervisory algorithms for optimum operation of an integrated hybrid renewable energy system. The studied system is based on a DC-coupled Wind/Photovoltaic Hybrid System (WPVHS), equipped with battery storage system, which delivers on the power grid in presence of a conventional generator. The purpose of the supervisory algorithms is to control, each of the different sub-systems, individually taking account of all power exchanges performed via the DC-link and the Point of Common Coupling (PCC). This is in order to manage the total energy supply. With the above mentioned supervision algorithms, the service continuity was assured by meeting the energy demand while optimizing the conventional sources use and replacing them, except in case of major deficit, by renewable ones. Our new algorithms have been tested via MATLAB software and the obtained results demonstrate the reliability and the robustness of the proposed strategy.
