SNOP优化配置的多维效用并合模型

智能软开关SNOP的优化配置需要考虑配电网运行效益及投资等多个优化指标,是一个多目标决策问题。因此在多维效用并合法的基础上,首先根据各个优化指标的内在特性及逻辑联系对SNOP的优化配置指标进行效用并合;随后以综合效用值最大为目标,建立SNOP优化配置的多维效用并合模型;最后,以IEEE 33节点系统为例,对所提出的优化模型进行了分析与验证。结果表明,基于多维效用并合法配置SNOP,能够以合理的SNOP安装容量实现系统有功损耗下降,改善系统电压水平及馈线负载平衡度,并能够提高分布式电源的消纳率,实现配电网综合优化运行。

Multi-attribute utility mergence model of SNOP optimal allocation

The optimal allocation of SNOP considering operation efficiency and investment of distribution network is a multi-objective problem,In this paper,a multi-attribute utility mergence method is proposed.Firstly,mergence rules are identified to achieve the aggregate utility according to the internal characteristic and logic relation of optimi-zation indexes.Then,a SNOP allocation optimixation model is built with the max aggregate utility value as the object.Finally,a case study of IEEE 33-bus system is included to verify the effectiveness of the proposed model and method.It is shown that the multi-atribute utility method for SNOP allocation can decrease active power losses,.improve the system voltage level and load balancing level and increase the distributed generation penetration with a reasonable SNOP capacity.
