Multi-Objective Optimization Scheduling Method for Distribution Network with Distributed Energy

为提高配电网运营收益,降低其供配电过程中的能源损耗,以含分布式能源的配电网为例,开展多目标优化调度方法的设计研究。将经济目标和能源损耗目标作为调度目标,建立配电网优化调度多目标函数;考虑配电网的物理限制、运行要求以及经济和环境因素,采用设计函数约束条件的方式,对建立的经济成本优化目标函数中的参数进行约束;引进粒子群算法,评估粒子在搜索空间的适应度,以实现对配电网协同调度优化。对比实验结果证明,设计的方法可以在达成配电网经济目标,提高配电单位运营收益的同时,降低配电网在运行中的能源损耗,提高对电能的利用率。

In order to improve the operational revenue of the distribution network and reduce energy losses during its power supply and distribution process,a multi-objective optimization scheduling method is designed and studied using a distribution network with distributed energy as an example.Establish a multi-objective function for distribution network optimization scheduling by taking economic goals and energy loss goals as scheduling objectives.Considering the physical limitations,operational requirements,as well as economic and environmental factors of the distribution network,the parameters in the established economic cost optimization objective function are constrained by using design function constraints.Introduce particle swarm optimization algorithm to evaluate the fitness of particles in the search space,in order to achieve collaborative scheduling optimization of distribution networks.The comparative experimental results demonstrate that the designed method can achieve the economic goals of the distribution network,improve the operating income of the distribution unit,reduce energy loss during operation of the distribution network,and improve the utilization rate of electrical energy.
