以孤立微电网最优经济运行为研究对象，研究了铅酸蓄电池充放电深度和次数对其寿命的影响，并折算为经济成本。针对风电机组出力间歇性对系统运行备用的影响，采用概率约束反映旋转备用配置的置信水平，最终建立孤立微电网最优经济运行模型。采用启发式调整策略与粒子群算法相结合的方法对优化模型进行求解。以某孤立微电网为例进行算例分析，验证了所提模型和算法的可行性，并进一步讨论了铅酸蓄电池寿命损耗成本、旋转备用配置、电源出力调整策略等对最优经济运行计划的影响。

Taking the optimal economical operation of isolated microgrid as research object, the impacts of the times and the depth of charge/discharge of lead-acid battery on its lifetime are researched and converted into its economic cost. In allusion to the impact of the intermittence of the output of wind power generating units on the spinning reserve of power grid, the probability constraint is used to reflect the confidence level of the configured spinning reserve, and finally an optimal economical operation model of isolated microgrid is established. The integration of heuristic adjusting strategy with particle swarm optimization is adopted to solve the optimization model. Taking a certain isolated microgrid as example, the analysis of example is performed to validate the feasibility of the proposed model and algorithm, and the impacts of the cost of lead-acid battery life loss, the configuration of spinning reserve and the adjusting strategy of power source output on optimal economic operating plan is further discussed.
