摘　　要：为适应微电网拓扑结构变化及智能体“即插即用”等要求,加快系统收敛速度,提出一种基于领导-跟随多智能体的改进有限时间一致性算法。该算法基于总体代价函数梯度算法项的传统有限时间一致性算法,引入增益系数和功率偏差消除项,运用李雅普诺夫稳定性定理和图论定理证明了改进算法的稳定性。随后,研究基于改进有限时间一致性的微电网经济调度策略。最后,通过算例验证该算法具有较优的动态和稳态性能,能够满足微电网拓扑结构变化等要求。To adapt to the changes in microgrid topology and the requirements of agents such as“plug and play”while speeding up the convergence rate of the system,an improved finite time consistency algorithm based on leader-follower multi-agent is proposed.This algorithm is based on the traditional finite time consistency algorithm for the gradient algo⁃rithm term in the overall cost function,introduces the gain coefficient and the power deviation elimination term,and us⁃es the Lyapunov stability theorem and the graph theory theorem to prove the stability of the improved algorithm.Then,an economic dispatching strategy for microgrid based on the improved finite time consistency is studied.Finally,the re⁃sults of a numerical example verify that the proposed algorithm has excellent dynamic and steady-state performances,which can meet the requirements including the changes in microgrid topology.
