Multi-operating Modes Based Energy Management Strategy of Virtual Power Plant

In this paper, a Virtual Power Plant (VPP) consists of a solar photovoltaic (PV) system, a wind turbine (WT) power generation system and an energy storage system (ESS) that is proposed in order to extenuate the utilization of fossil fuels on account of global warming and to cope with the increasing demand of electrical energy. These inexhaustible energy sources and the ESS are integrated to a common AC bus via double stage interfacing power converters. Multi-operating modes are generated by an Energy Management Strategy (EMS) that contingent on solar, wind and load power to control the scheduling operation of loads during dynamic weather and load conditions in order to avoid from blackout which is a primary focus of this paper. The PV and WT power generation systems are contemplated as the main sources of energy that satisfy the load demand in a regular manner whereas the battery is used only as a backup for the exigency. The modelling and the simulation of the presented VPP system are carried out under MATLAB/SIMULINK software. Simulation outcomes are shown and discussed that unveils the effectiveness and performance of the designed EMS.
