Energy management and coordinated control strategy of PV/battery AC microgrid in islanded operation
摘要
Abstract
Considering the relationship of energy supply and demand among PV, battery and load, a coordinated control strategy for energy management of PV/battery AC microgrid during islanded operation is proposed. The control strategy adopts master-slave control approach, in which the battery working as the main source is able to charge or discharge so as to provide stable voltage amplitude and frequency for both load and PV inverter; while the PV system as the slave source can work either in maximum power point tracking (MPPT) or power limitation mode (PLM) according to the internal power balance; and the load switching control guarantees sustainable power supply for important loads and prevents the battery from over discharge. Simulation results under different working conditions verify the correctness and effectiveness of the proposed control strategy.关键词
