摘要
针对电网分区管理的特点,采用以管理分区为计算单元的新的三级组织结构,将管理分区与优化分区有机结合起来,构建了多Agent系统。采用分解协调模型和辅助问题原理作为多Agent系统的算法,各分区并行计算,通过数据驱动的模型进行多Agent间的协商、协调,完成全网优化计算。文中以枣庄地区电网为例,建立了该系统的优化运行机制以及对现有多分区系统进行无功优化的方法。实际应用表明,该系统比不考虑多分区的优化方案加快了优化速度,降低了网损,提高了电压水平,为多Agent系统在大型电网无功电压优化中的应用提供了更加实用化的解决方案。
A new 3-hierarchical-level architecture, in which the management sub-region is designed as the calculation unit, is adopted to optimize the voltage/var in multi-regional power systems. The multi-agent system which combines the management sub-region with the optimization sub-region is proposed. By using a decomposition-coordination model, the distributed and parallel optimization algorithm, based on auxiliary problem principle, is carried out. The coordination and negotiation mechanism is accomplished by using the data-driven model to optimize the voltage/var in large, multi-regional power system. Taking the power network of Zao Zhuang, Shandong province, China as an example, this paper discusses the operation mechanism and the optimization method in existing multi-regional systems. Application case shows that this system provides more applicable solutions than the one that does not consider multi-regional interaction with faster optimization speed, less net losses and higher average voltage level in the application of the multi-agent system to the voltage/var optimization of large power system networks.
