摘要:
在极端灾害发生后电动汽车(electric vehicle,EV)可作为移动电源给负荷供电,从而支撑配电网韧性提升。针对配电网故障发生不可预见、正常态和故障态调度模型切换导致调度指令不稳定问题,文章研究了运行状态平滑切换的EV参与配电网韧性提升策略。基于EV状态和连接方式的二进制变量建立线性化EV时空动态模型,能适应EV灵活调度算力大的需求。考虑EV和交通网不确定性因素,建立基于交通网和配电网信息实时滚动更新的正常态和故障态统一调度模型,正常态以经济性和韧性最优为目标,故障态以韧性最优为目标,通过引入状态表征参数实现两种状态间平滑切换。算例仿真表明,该策略在不影响精度的情况下显著降低了计算量,有助于实现配电网最优韧性恢复和状态平稳过渡。
