【摘要】：大规模分布式电源的接入对配电网无功优化提出了巨大的挑战,而传统集中优化存在依赖中央控制器,易产生通信堵塞等弊端。为提高主动配电网无功电压控制的可靠性,采用二阶锥松弛技术建立了主动配电网无功优化模型,并基于辅助问题原理提出了一种主动配电网分区分布式无功优化控制方法,并进一步提出了边界变量标准化处理方法,以提高分区无功优化的收敛速度,实现全局网损优化。基于所提优化方法,各个分区仅需采集区内功率电压信息,并与相邻分区交互边界变量即可实现无功调度和全局网损优化,保证系统电压质量。最后,基于IEEE 69节点配电系统进行仿真,验证了所提控制方法的有效性。
[Abstract]:The access of large-scale distributed generation poses a great challenge to the reactive power optimization of distribution network, while the traditional centralized optimization depends on the central controller. In order to improve the reliability of reactive power and voltage control in active distribution network, the reactive power optimization model of active distribution network is established by using second-order cone relaxation technique. Based on the principle of auxiliary problem, a distributed reactive power optimal control method for active distribution network is proposed, and a standardized method of boundary variable processing is proposed to improve the convergence speed of zonal reactive power optimization. Based on the proposed optimization method, each partition only needs to collect the power and voltage information in the area, and interact with the adjacent partition boundary variables to achieve reactive power scheduling and global network loss optimization. Finally, simulation based on IEEE 69 bus distribution system is carried out to verify the effectiveness of the proposed control method.
