摘要
由于可再生能源的随机性，储能系统是自主混合能源系统的重要组成部分。在本文中，新的重力储能(GES)技术使用悬吊重量被纳入一个独立的太阳能风能混合动力系统。模拟工作考虑了印度古吉拉特邦的气象资料。本文提出了可再生能源、发电机组和GES的数学模型。本文主要研究了单机混合电力系统可靠性评估的概率分析方法。为了评价系统的可靠性程度，对可靠性指标EENS (Expected energy not served)和LOEP (Loss of energy probability)进行了评价。
Probabilistic Analysis Of Solar-Wind Gravity Energy Storage For Off-Grid Communities
Energy storage systems are essential parts of autonomous hybrid energy systems due to stochastic nature of renewable resources. In this paper, the new Gravity energy storage (GES) technology using suspended weight is incorporated into a standalone solar-wind based hybrid power system. Meteorological data of Gujarat (India) were taken into account for the simulation work. This paper presents mathematical modeling of renewable energy resources, generating units, and GES. This work focuses on the probabilistic analytical approach for reliability evaluation of standalone hybrid power system. To evaluate the degree of reliability, the reliability indicator Expected energy not served (EENS) and Loss of energy probability (LOEP) are evaluated.
