| Summary: | This article is designed to control the stability and the effective operation in a different entity of DC microgrid(MG) under varying climatic and load conditions. The proposed MG contains primarily renewable sources including photovoltaics (PV) commanded by a DC-DC boost converter additionally the wind power conversion system with a turbine wind, a permanent magnet Synchronous Generator (PMSG), a three-phase diode rectifier, and ultimately a DC-DC buck-boost converter. In addition, this system also includes a battery energy storage system (BESS) with a bidirectional DC-DC. The last component is the variable DC charge. The general purposes of this paper are the following firstly, obtaining the maximum power from PV and wind energy by using the perturb and observation method and by operating the boost converter and the buck-boost. Second, maintain the DC bus voltage as a constant value. Lastly, the management of energy and storage by controlling the bidirectional converter. The structure of energy conversion is elaborated by the mathematical model, controlled by a nonlinear technique which is the integral sliding mode control (ISMC). The robustness, performance, and efficiency are demonstrated with a simulation in MATLAB/SIMULINK. |
