电能存储（EES）的使用在能源生产向可再生能源（RESs）的过渡中起着重要作用。为了应对可再生能源系统的波动，确保可靠的能源供应，有效地确定可再生能源系统的规模是非常重要的。本文提供了一种方法，有助于确定构思完全独立系统所需的最小EES大小。该方法基于给定设计周期的能量平衡评估，也可用于确定并网应用中电力系统的规模。该方法通过从两个不同系统获得的测量数据进行验证：a)具有本地发电源的接近零能耗建筑，b)安装在工厂并用于调峰的大型电池储能系统（BESS）。通过估算EES系统所需的规模，得到的结果证实了所提出方法的有效性。在考虑的系统中，估计的BESS尺寸和安装的BESS尺寸之间存在良好的相关性。BESS实际容量与估计容量之间的偏差小于5%。
The use of the electrical energy storage (EES) plays an important role in the transition of energy generation towards renewable energy sources (RESs). An effective sizing of EES systems is very important in order to cope with the volatility of RESs and to ensure a reliable energy supply. The present paper provides a methodology which helps to determine the minimum required EES size for conceiving a fully standalone system. Its approach is based on the evaluation of the energy balance for a given design period, and it can also be applied for sizing the EES system in grid-connected applications. The methodology was validated using measurement data obtained from two different systems corresponding to: a) a near-zero energy building with local generation sources, and b) a large-scale battery energy storage system (BESS) installed in a factory and used for peak-shaving. The obtained results confirmed the effectiveness of the proposed methodology by estimating the required size of the EES system. A good correlation was found between the estimated and the installed BESS size in the considered systems. The deviation between real and estimated BESS capacities was found to be less than 5%.
