| 摘要: |
| 应用多智能体协调控制理论来实现含分布式电源的配电网的电压协调控制，以提高配电网的静态电压稳定性。首先对含分布式电源的配电网进行电压稳定性分析，根据系统各节点的电压失稳系数判断系统中的电压稳定性薄弱节点；其次对配电网中的分布式电源进行虚拟发电厂等效，提出同时利用虚拟发电厂和配电网常规调压设备实现配电网电压协调控制的框架体系。应用多智能体协调控制理论得出电压稳定性协调控制的数学模型，设计多智能体的反馈控制器。仿真结果验证了所提方法的正确性和有效性。 |

| Abstract: |
| The multi-Agent coordinated control theory is adopted to realize the coordinative voltage control of distribution network with distributed generations for improving its static voltage stability. The voltage stability of distribution network with distributed generations is analyzed and the weak nodes are identified according to their voltage instability coefficients. A framework of coordinative grid voltage control is proposed，which treats the distributed generations as equivalent VPP（Virtual Power Plants） and utilizes them，together with the conventional voltage regulation equipment，to achieve coordinative grid voltage control. Its mathematical model is derived based on the multi-Agent coordinated control theory and the multi-Agent feedback controller is designed. Simulative results show the correctness and effectiveness of the proposed method. |
