Single-phase Microgrid with Dual Photovoltaic Array for Efficient Power Balance based on Power Conditioning System
Abstract—Abstract This paper proposes a single-phase microgrid based on a power conditioning system with dual photovoltaic array and an energy storage. A grid-connected inverter and battery charger are adopted for energy conversion from the two arrays of different construction. The power conditioning system based on a bidirectional inverter delivers power among grid, load, and storage using the grid-connected mode and island mode. The performance of the microgrid was verified by simulation of three microgrid operations.The microgrid is a localized power grid generating power from distributed energy resources, which can be connected to a utility grid for the stable supply or disconnected for the standalone operation.
