Mohammad Ghasemi Damavandi, Vikram Krishnamurthy, Jose R Marti

摘要:

研究了有源智能电网中的电压无功优化问题。主动智能电网配备了分布式发电机、分布式存储系统和允许拓扑重构的联络线开关。在本文中,联合操作的遥控开关,存储单元,有载分接开关,并联电容器制定了一天前的操作计划。建议的VVO问题的目标是最小化系统中的预期有功功率损耗,并制定为一个混合整数二次规划。通过一阶马尔可夫链模型来描述风力发电的随机性。一个33节点,12.66千伏主动智能电网使用的智能电表和风力涡轮机的真实数据的数值结果,并比较各种测试情况。

英文摘要:

This paper considers the problem of Volt-VAR Optimization (VVO) in active smart grids. Active smart grids are equipped with distributed generators, distributed storage systems, and tie-line switches that allow for topological reconfiguration. In this paper, the joint operation of the remotely controllable switches, storage units, under load tap changers, and shunt capacitors is formulated for a day-ahead operation scheme. The proposed VVO problem aims at minimizing the expected active power loss in the system and is formulated as a mixed-integer quadratic program. The stochasticity of the wind power generation is addressed through a first-order Markov chain model. Numerical results on a 33-node, 12.66 kV active smart grid using real data from smart meters and wind turbines are presented and compared for various test cases.
