微网中负荷与储能装置的协调优化是促进可再生能源的利用，提高微网运行经济性的重要手段，但同时将直接改变用户的用电习惯和储能装置的运行特性，进而影响微网的可靠性。本文通过建立负荷与储能装置的协调优化模型，并基于时序蒙特卡洛模拟法，将该模型与微网可靠性评估相结合，实现在微网可靠性评估中计及负荷与储能装置协调优化的影响。此外，定义了新的负荷、储能装置以及微网整体的可靠性指标，对该影响进行定量化评估。通过算例分析，验证了上述模型、方法及指标体系的有效性。计算结果表明，计及负荷与储能装置协调优化影响使得评估更加符合微网的运行实际，对制定合理的微网运行方案，提高其可靠性和经济性具有重要的意义。

For microgrids, coordinative optimization of loads and storage devices is an important approach that promotes the utilization of renewable energy and economic operation. However, the optimization directly changes the customers’ consumption habits and the operation status of storage devices, and affects the reliability of microgrids. This paper establishes optimization models for loads and storages, which are integrated into the reliability evaluation of microgrids by a sequential Monte Carlo method.The integration realizes the consideration of the coordinative optimizationin reliability evaluation of microgrids.Besides, new reliability indices are defined to quantify the impacts of the optimization on the reliability of customers, storage devices and microgrids. Extensive results indicate the effectiveness and accuracy of the presented models and methods. With consideration of the load and storage optimization, the results are of significance to make microgrid operation plans andimprove the reliability and economy of microgrids.
