【摘要】：为保证频率和联络线功率的控制效果及合理利用全网的AGC调节资源,提出了一种基于合作博弈理论的互联电网AGC协调控制。根据频率偏差绝对值的大小对系统运行状态进行等级划分,等级不同控制区频率偏差系数的设定方式不同,实现区域电网间AGC控制的协调配合。建立了AGC协调控制中各控制区收益的数学模型,包括互为备用少设置AGC调节容量所节省的费用模型和承担控制区之外调频责任所花费的费用模型,当系统处于联合调频区时,采用合作博弈的Shapley值和核仁模型对各控制区的收益通过周期性改变频率偏差系数的方法调整承担调频责任所花费的费用,实现各控制区收益的优化分配。采用三控制区互联电力系统进行仿真,结果验证了基于合作博弈理论的互联电网AGC协调控制的有效性。
[Abstract]:In order to ensure the control effect of frequency and tie-line power, and to make rational use of the AGC regulating resources of the whole network, a coordinated AGC control based on cooperative game theory is proposed. According to the absolute value of frequency deviation, the operating state of the system is classified, and the frequency deviation coefficient of different control areas is set in different ways, so the coordination of AGC control among regional power networks is realized. The mathematical model of the revenue of each control area in the coordinated control of AGC is established, which includes the cost model saved by setting up the regulating capacity of AGC for each other and the cost model of assuming the responsibility of frequency modulation outside the control area. When the system is in the joint frequency modulation area, The Shapley value of cooperative game and the kernel model are used to adjust the cost of assuming the frequency modulation responsibility by periodically changing the frequency deviation coefficient to realize the optimal distribution of the income in each control area. The simulation of interconnected power system with three control areas is carried out. The results show that the AGC coordinated control based on cooperative game theory is effective.
