摘　　要：微电网中的能源优化调度旨在通过制定最低发电成本的目标,找到最优的设备发电策略。首先建立了一个基于多智能体的微电网模型,充分考虑了微电网运行总负荷随时间变化的动态性。为了解决考虑时变负荷的发电成本最小化问题,进一步设计了一种分布式固定时间时变算法。优化问题的目标函数被定义为所有局部凸目标函数的总和,并受等式约束的限制。在理论上,通过构造李雅普诺夫函数,证明了该算法的稳定性和收敛性。这一理论基础为算法在实际应用中的可靠性提供了保障。数值仿真实验结果显示,所提出的算法能够成功解决微电网能源优化调度问题。这不仅为微电网管理提供了有效工具,也为能源系统的可持续发展提供了有力支持。通过最小化发电成本,微电网能够更高效地满足不断变化的负荷需求,从而提高系统的经济性和可持续性。这项研究为微电网的智能化管理和未来能源系统的设计提供了有益的参考。Energy optimization dispatch within microgrid aims to minimize generation costs by formulating the objective of achieving the optimal device generation strategy.This paper establishes a microgrid model based on multiple intelligent agents,fully considering the dynamic nature of the total load in the microgrid as it varies over time.To address the minimization of generation costs while accounting for time-varying loads,a distributed fixed-time time-varying algorithm is further designed.The objective function of the optimization problem is defined as the summation of all local convex objective functions,subject to constraints imposed by equations.The theoretical foundation of this study involves proving the stability and convergence of the algorithm through the construction of a Lyapunov function.This theoretical underpinning ensures the reliability of the algorithm in practical applications.Numerical simulation experiments demonstrate that the proposed algorithm effectively resolves the energy optimization dispatch problem within microgrid.This not only furnishes a potent tool for microgrid management,but also lends robust support to the sustainable development of energy systems.By minimizing generation costs,microgrid can efficiently meet the constantly evolving demands of loads,thereby enhancing the economic efficiency and sustainability of the system.The research provides valuable insights for the intelligent management of microgrids and the design of future energy systems.
