- Abstract
- This paper proposes a three-phase microgrid which consists of two renewable energy sources, an energy storage, and a power conditioning system (PCS). The renewable energy generated from the photovoltaic arrays is provided to a load and the storage through an inverter and a charger, respectively. The PCS coordinates the energy flow from the sources such as a utility grid and the renewable energy sources to the storage and load, and vice versa. The microgrid based on the PCS operates alone as an island operation, which is determined autonomously according to the state-of-charge (SOC) of the storage. The autonomous island operation of the microgrid was verified through simulations using a PSIM tool.
