【摘要】：经济运行、频率和电压控制及系统稳定性是微电网实时控制的主要内容。基于多智能体系统一致性协议,提出了一种分层分布的实时优化策略。首先,在仅考虑分布式电源出力约束的条件下,应用一阶一致性实现对分布式电源有功出力的控制,优化运行成本;其次,针对下垂控制特性,提出了一种新的二阶一致性协议,用于实现分布式电源功率的精确控制;最后,应用一致性协议实时协调分布式电源的下垂参数,实现了系统频率和电压的优化。通过Lyapunov直接法对所提策略进行稳定性分析,证明系统是渐进稳定的。仿真分析及结果验证了所提策略的有效性。
[Abstract]:The economic operation, frequency and voltage control and system stability are the main contents of the real-time control of the micro-power grid. Based on the agreement of the multi-agent system, a real-time optimization strategy for hierarchical distribution is proposed. First, under the condition that only the output of the distributed power supply is considered, the first order consistency is applied to control the active output of the distributed power supply, and the operation cost is optimized; secondly, aiming at the sag control characteristic, a new second-order consistency protocol is proposed, And finally, a consistency protocol is applied to coordinate the droop parameters of the distributed power supply in real time, and the system frequency and the voltage optimization are realized. The stability analysis of the proposed strategy is carried out by Lyapunov direct method, and it is proved that the system is gradual and stable. The simulation analysis and the results verify the validity of the proposed strategy.
