摘要
搭建电动汽车充换电站参与电网自动发电控制(AGC)功率分配的框架,并建立其优化数学模型。在此基础上,提出电动汽车参与AGC功率分配的成本一致性算法。智能体间采用虚拟一致性变量作为一致性交互计算信息,同时以真实一致性变量确定电动汽车的AGC功率,提高算法的应用灵活性。某电网模型仿真结果表明:成本一致性算法可以减少电网调节成本,提高区域电网的控制性能标准,且能有效实现电动汽车参与电网AGC功率分配的自律调频。
A framework of electric vehicle charging station participating in the AGC power allocation of grid is constructed and its optimal mathematical model is established,based on which,a cost consensus algorithm of electric vehicle charging station participating in AGC power allocation is proposed. In order to improve the application flexibility of algorithm,the virtual consensus variables are taken as the information of consensus interactive calculation among agents while the actual consensus variables are adopted to determine the AGC power of electric vehicle. Simulative results of a power grid model show that,the proposed algorithm can reduce the regulation costs and enhance the AGC performance of power grid,and can also effectively achieve autonomous frequency regulation of electric vehicles participating in AGC power allocation.
