摘要
“双碳”目标下高比例可再生能源接入配电系统,造成了系统运行成本过高、弃风量过大等问题。针对上述问题,提出了一种综合考虑碳交易机制和需求响应的配电系统动态重构方法。首先,将垃圾电站以分布式电源的形式接入配电系统,改善系统能源分布结构,提升配网系统运行稳定性和经济性;其次,分别引入碳交易机制和需求响应,构建考虑碳交易机制和需求响应的配电网动态重构模型;再次,利用二阶锥松弛的方法简化非凸条件,降低求解难度;最后,基于改进后的IEEE33节点配电网模型进行验证,分析了所提方法对系统总运行成本、弃风量以及节点电压等因素的影响。算例结果表明,综合考虑碳交易机制和需求响应的配电系统重构方法可以明显降低系统总运行成本和弃风量。
Under the"carbon peaking and carbon neutrality"goals,a high proportion of renewable energy connected to the distribution system gives rise to high operating costs and excessive power loss of wind turbine generators.To solve these problems,a dynamic reconfiguration method of distribution system is proposed in this paper,which takes carbon trading mechanism and demand response into consideration.First,the garbage-fueled power station is connected to the distribution system in the form of distributed power supply to improve the energy distribution structure of the system and improve the operation stability and economy of the distribution network system.Second,the carbon trading mechanism and demand response are introduced respectively to build a dynamic distribution network reconstruction model considering carbon trading mechanism and demand response.Third,the second order cone relaxation method is used to simplify the non-convex conditions and reduce the difficulty of solving them.Finally,based on the improved IEEE33 node distribution network model,the influence of the proposed method on the total operating cost of the system,wind turbine generators power loss and node voltage is analyzed.The results of the example show that the distribution system reconfiguration method considering carbon trading mechanism and demand response can significantly reduce the total operating cost and power loss of wind turbine generators.
