中文摘要： 近年来，独立型微网系统在改善远离大陆的海岛及偏远山区的用电环境方面得到了越来越多的重视，独立型微网系统的优化配置是能否发挥微网系统自身优越性的关键要素。当前独立型微网系统优化配置理论考虑因素尚不全面，本项目在充分计及需求侧响应、系统寿命损耗特性以及储能系统性能下降等因素的基础上，开展基于智能优化算法的多目标优化配置研究。项目以独立型微网系统需求侧响应机理、发电与寿命损耗特性以及两者的耦合关系为研究内容，建立需求侧响应模型、发电与寿命损耗耦合模型，发展经济指标与性能指标等多目标下的优化方法，以确定全寿命周期内最优容量配置、电源类型以及能量管理策略多方面的参数。基于建立的模型及优化方法，详细分析影响优化配置结果的关键因素，以及不同优化目标对优化配置结果的影响，并作进一步的敏感性分析。该项目的研究成果解决了独立型微网系统优化配置中模型单一、考虑因素不全面等问题，提高优化配置的准确性和实用性。

英文摘要： In recent years, the application of stand-alone microgrid systems in improving electricity conditions of islands far from the mainland and remote mountain areas has been received more and more attention. The optimal configuration is the key element for stand-alone microgrid systems to play their own superiority. The factors considered in the current stand-alone optimal configuration theory are not yet complete. Based on intelligent optimization algorithms, this project carries out multi-objective optimization taking into account the demand-side response, life loss characteristics, and performance degradation of energy storage systems, etc. The research content includes stand-alone microgrid system demand-side response mechanism, power generation and life loss characteristics, and their coupling relationship. This project establishes demand-side response model, and power generation and life loss coupling model, develops multi-objective optimization method with economic indicators and performance indicators in order to determine the optimal capacity configuration, power types, and energy storage management strategy in the whole life cycle. Based on the established model and optimization method, the key factors affecting the optimal configuration results as well as the influences of different optimization objective
