Comprehensive Control Strategy and Modeling for Grid-Forming PV-ESS-EV Microgrid
摘要
With the continuous development of new energy generation, it is crucial to integrate distributed generation (DG) like the photovoltaics (PV) and ensure its operational stability through some control strategies. In this paper, a comprehensive control strategy and modeling of a PV-ESS-EV microgrid is designed. The PV boost converter uses the maximum power point tracking (MPPT) control and the electric vehicle (EV) charging piles charge and discharge with a dual-active bridge (DAB) topology. The energy storage system (ESS) uses a constant voltage control to maintain the DC-bus voltage stability. A virtual synchronous generator (VSG) control strategy is used for the grid-tied converter. The PV-ESS-EV microgrid modeling is built and the effectiveness of the comprehensive control strategy is validated.
