These networks are called standalone microgrid systems. In this paper, a standalone micro-grid system consisting of a Photovoltaic (PV) and Wind Energy Conversion System (WECS) based Permanent Magnet Synchronous Generator (PMSG) is being designed and controlled.
Moreover, these can be useful for remote area electrification where the power supply from the mainstream grid is nonviable and high-rise urban apartments for stable and sustainable power supply. A microgrid is an integration of distributed renewable energy resources (DRERs), integrated systems with loads, and energy storage devices 3.
Table 1 presents the design and performance metrics for three configurations. It is noted that the 1728.7kW of Wind energy generation system, 885kW of PV, and 28648kWh of battery is the optimal size for this given microgrid system. The generated wind, PV, and battery power for one one-year time scale are shown in Fig. 5.
Proposed PV-wind microgrid system The block diagram of the proposed PV-Wind microgrid system is shown in Fig. 1. The PV and Wind Turbine Generator (WTG) are connected to the DC-DC converter to step up the respective voltage outputs to the DC-AC inverter-dictated level. The DC-DC converter performs the MPPT operation.
