摘要近年来以清洁能源为燃料的分布式发电越来越受到人们的重视。但是分布式发电直接接入电网，会造成电压等的波动，对电网稳定性产生影响。人们提出了微电网来管理分布式发电。其中，微电网能量优化调度尤其重要。研究了微网中各微电源，储能单元的模型。提出了微网四种不同的调度策略，选择了三种优化目标。三种优化目标分别是运行费用最少，环境污染最小和综合费用最小。运用了动态规划法求解相应的调度策略。通过几个算例，研究了优化目标不同、可再生能源竞争力、微网运行模式不同、市场政策等因素对能量优化调度的影响，验证了模型和算法的有效性。65005

Title Research on Micro-Grid Energy Optimization Scheduling Algorithm
Abstract In recent years, people are paying more attention to distributed power generation which is fueled by clean energy. However, when connected to the grid, distributed power generation will directly cause the fluctuations of voltage, etc in grid and have an impact on stability of the power grid. So people put forward the conception of the micro-power grid to manage the distributed power generation. Therefore, research on micro- grid energy optimization scheduling is especially important. The passage analyses the model of micro-power and energy storage unit ,propose four different micro-grid scheduling strategy and chooses three targets of optimization. These targets are minimal running costs, minimize environmental pollution and integrated minimum cost. I select the dynamic programming method to solve the corresponding scheduling policy. Through several examples, Operation modes of MG，the competitiveness of renewable sources, market policies factors and demand-side managements have been focused on for energy optimal scheduling results．A relevant example ascertains the feasibility of the models，strategies and algorithm．
