Abstract:

通过日前多时段优化,可以为主动配电网中的分布式电源、无功补偿装置和储能装置安排合理高效的生产计划,以达到调节电压水平、提高能源资源利用率、节能降损的目的。首先建立基于三相Distflow潮流的辐射状配电网有功-无功协调动态优化模型。该模型考虑分布式电源出力、储能装置充放电功率、电容器阻投切等连续和离散决策变量,是一个典型的混合整数非凸非线性规划。该类模型缺乏严格高效的求解方法。为此,采用二阶锥松弛技术将其中的三相潮流方程进行凸化松弛,使得优化问题转化为可有效求解的混合整数二阶锥规划模型。最后,采用扩展的IEEE33节点三相测试系统仿真计算,利用MOSEK等算法包求得电网中各设备动作时刻和投运容量,验证了所提方法寻优稳定、松弛精确、计算高效等特性。
