摘要：5G的快速发展使得5G基站储能容量大幅增加,如何充分发挥时常处于休眠状态的基站储能资源,使其参与配电网供电恢复,降低配电网失电量问题亟待研究.该文通过协调基站储能参与配电网供电恢复,以发挥其储能价值.首先,建立风光联合出力场景集,通过赤池信息准则和平方欧式距离确定各时段最优Copula函数,进而对其进行抽样聚类,获得风光典型出力场景集;然后,建立基站备用储能模型,通过正弦函数叠加建立不同区域的通信量模型,利用泰尔熵和修正基尼系数建立综合脆弱度模型确定各基站储能备用时间及备用储能模型,进而获得不同基站储能的可调度容量;最后,以失负荷量损失最小为目标,建立考虑基站储能参与及风光出力波动的含可调参数的两阶段鲁棒优化模型.以改进的IEEE33节点模型为例进行仿真验证,分别对比了定基站备用时间与该文所提方法确定备用时间、鲁棒优化与确定性优化等方案下系统失负荷量的变化情况.仿真结果表明,5G基站储能可降低失负荷量损失成本,提高风光消纳率.
