摘要: 随着分布式电源和电动汽车等灵活性电力资源大量接入配电网,对系统安全可靠性提出了更高要求。提出一种考虑分布式电源和电动汽车集群调度的配电网络重构方法,以提高系统可靠性和经济性。在考虑电压偏差的基础上,以故障停电损失成本作为衡量电网可靠性的经济性指标,对网络拓扑结构进行重新构建。首先以线路的开关状态、电动汽车充、放电状态及功率为决策变量,建立以综合成本最小为目标的配电网络重构模型;然后针对配电网络重构模型,采用共生生物搜索算法进行模型求解;最后,通过仿真算例验证了所提方法的有效性。

Abstract: Along with the connection of numerous flexible resources such as distributed generation and electric vehicles (EVs) to distribution networks, higher requirements are raised on system security and reliability. A distribution network reconfiguration method based on distributed generation and EV cluster scheduling is thus proposed to improve the system security and reliability. With consideration of voltage deviation, the network topology structure is reconstructed by taking the failure loss cost of power grid as an economic index to measure the power network reliability. Firstly, a distribution network reconfiguration model is established to minimize the comprehensive cost by taking the switching state of power lines, the charging and discharging state and power of EVs as decision variables. Then, the symbiotic search algorithm is used to solve the reconfiguration model. Finally, the effectiveness of the proposed method is verified via simulation of a distribution system.
