为提高和改善微网中电压支撑动态特性,结合多智能体控制思想,提出各微源间电压支撑动态协调控制方法。分析了微网网络特性,推导了分布式电源节点对其它节点电压支撑调节的关系模型,并采用agent控制理论,建立了执行级agent电压支撑决策行为的向量函数,与电压目标评价向量进行最优时序判据运算,进而构成协调控制算法。依据该算法对各分布式电源agent的出力补偿进行时序判断,形成电压支撑动态性能的最优控制模式,使故障发生后电压随着微源间功率的协调补偿得到快速稳定的支撑。应用典型的芬兰乡村微网模型进行数字仿真,结果证明了该方法具有良好的鲁棒性及适应性。
In order to improve and improve the dynamic characteristics of voltage support in microgrids and to combine the idea of multi-agent control, a dynamic coordination control method of voltage support between micro-sources is put forward. Based on the analysis of the characteristics of microgrid networks, the model of the relationship between distributed power nodes and other nodes’ voltage support regulation is deduced. By using agent control theory, the vector function of voltage support decision-making behavior of executive agents is established, Timing criterion calculation, and then constitute a coordinated control algorithm. According to the algorithm, the output of each distributed power agent is compensated for timing, and the optimal control mode of dynamic performance of voltage support is formed. After the fault occurs, the voltage can be quickly and stably supported with the coordinated compensation of power between micro sources. The typical Finnish rural microgrid model is used for numerical simulation. The results show that this method has good robustness and adaptability.
