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

Economic dispatch

frequency and voltage control

and system stability are still important problems in real-time control for microgrid. Based on the consensus protocol of multi-agent system

this paper presents a hierarchical distribution real-time optimization strategy. Firstly

a first-order consensus protocol is applied to calculate the active power of distributed generators(DGs)when only the constraint on output power is to be considered. Secondly

based on the secondary-order agent model of active power regulation for DGs

a novel consensus protocol is proposed to make the DG export the reference active power given in the first layer. Finally

the consensus protocol is used to adjust the droop parameters adaptively so that the system frequency and voltage are optimized as expected. The system is in globally asymptotic stability under the proposed strategy through the analysis of Lyapunov direct method. Simulation analysis and results have verified the effectiveness of the proposed strategy.
