适应多类型电网故障的储能系统预测电流控制与LVRT策略
A low voltage ride through technology adapting to multi-grid fault of battery energy storage system
摘要
Abstract
In order to realize low voltage ride through (LVRT) by controlling the power conversion system (PCS) of the energy storage device in the situation of both the balance and unbalance grid voltage fault, considering the shortage of power conversion system (PCS), and by analyzing the predictive current control principle, this paper derives PCS instantaneous power equation inα-βcoordinate system and designs a strategy to realize LVRT fault control. Then it builds a single battery module (84 kW) control system based on the PSCAD to simulate multiple types of grid fault. After the existing control strategy is simulated and verified by the software simulation, the strategy is transplanted to the hardware facilities in the experiment. The results show that this control strategy can effectively achieve the LVRT function in the energy storage system.关键词
