可再生能源，特别是与微电网技术相结合的太阳能和风能，为偏远社区提供了重要的机会，以提供电力供应，改善当地能源安全和生活条件。太阳能、风能和储能的结合使偏远社区的可持续能源发电成为可能，并使能源成本低于柴油发电。本研究的目的是优化系统设计的建议混合太阳能-风能-抽水蓄能系统在独立模式下的隔离微电网的规模为几百千瓦。提出了系统主要部件的初步设计过程，并根据技术经济评价进行了优化。进一步研究了零供电概率下的最优系统配置问题。此外，太阳能-风能混合系统，太阳能单独和单独的风力发电系统与抽水蓄能在LPSP从0%到5%的系统性能进行了研究和比较。结果表明，增加风力涡轮机可以导致较低的能源成本（COE），并有助于减少能量存储的大小。还对几个关键参数进行了敏感性分析，以检查它们对系统COE的影响。(C)2014爱思唯尔有限公司版权所有。
Renewable energy, particularly solar and wind power integrated with microgrid technology, offers important opportunities for remote communities to provide power supply, improve local energy security and living conditions. The combination of solar, wind power and energy storage make possible the sustainable generation of energy for remote communities, and keep energy costs lower than diesel generation as well. The purpose of this study is to optimize the system design of a proposed hybrid solar-wind-pumped storage system in standalone mode for an isolated microgrid of a scale of a few hundred kW. The initial design process of the system's major components is presented, and then optimized based on a techno-economic evaluation. The optimal system configuration under zero loss of power supply probability (LPSP) is further examined. In addition, the system performance of hybrid solar-wind, solar-alone and wind-alone systems with pumped storage under LPSP from 0% to 5% is investigated and compared. Results demonstrate that addition of wind turbine can result in a lower cost of energy (COE) and help reduce the size of energy storage. Sensitivity analysis on several key parameters is also performed to examine their effects on system COE. (C) 2014 Elsevier Ltd. All rights reserved.
