摘要
由于当前配电网技术使配电网系统的有功损耗增加,出现网损数值增加、渗透率较低等问题,提出考虑需求侧响应的配电网柔性软开关优化控制方法。首先,建立需求侧响应模型与柔性软开关优化控制模型;然后,利用粒子群算法对模型进行求解,完成配电网负荷转移的设计;最后,通过设定柔性软开关运行、配电网系统潮流及可再生能源发电出力等约束条件完成配电网柔性软开关控制优化。实验证明,应用本文方法可有效转移配电网系统的负荷,大幅度降低配电网系统的有功损耗电量及整体网损量,提升配电网系统的渗透率与消纳可再生能源发电的能力,实现对配电网系统的运行优化,为配电网系统的安全经济运行提供保障。
Since the existing distribution network technology increases the active power loss of distribution network system,problems such an increase in the network loss value and a lower penetration rate will arise.To solve these problems,the research on the optimal control method for the flexible soft switch in distribution network considering demand-side response is proposed.First,a demand-side response model and an optimal control model of flexible soft switch are established.Then,the particle swarm optimization algorithm is used to solve these models,and the design of load transfer in distribution network is completed.Finally,the constraint conditions such as the operation of flexible soft switch,power flow in distribution network system and output from renewable energy power generation are set,thereby realizing the optimization of the control of flexible soft switch in distribution network.Experimental results show that after the application of the proposed method,the load of distribution network system can be effectively transferred,the active power loss of distribution network system and the overall network loss can be greatly reduced,and the penetration rate of distribution network system and the consumption of renewable energy power generation can be improved.As a result,the operation optimization of distribution network system is realized,providing a guarantee for its safe and economic operation.
