Storage de-rating factors methodology review
The technical availability calculation is a complex process to collect, clean and process data sources. Only a significant minority (~25% of installed MW capacity) of battery storage units have complete, concurrent maximum export limit (MEL) and available energy (MWh) data of sufficient data quality. We would welcome efforts to improve data quality, particularly for MEL and available energy data . As the number of batteries connected on the system increases, we will review the viability of running this process annually.
BATTERY ENERGY STORAGE SYSTEMS: MODELLING ...
论文的第一部分提供了有关BES的参考框架，并基于文献分析以及实验活动。第2章概述了电化学存储选择（预期性能，市场份额，成本），并特别注意锂离子技术。第3章介绍了三种不同的锂离子化学分子的实验测量。能量密度，功率密度和效率用于讨论实际应用中的BESS性能。第4章提出了有关电池建模的文献综述，该综述归类为四种一般不同的方法：电化学，分析（经验），电气和随机性。为电池模型确定了两个主要任务：操作条件的估计（即SOC估计），寿命的估计（即SOH估计）。
BATTERY ENERGY STORAGE SYSTEMS (BESS)
A 22.5 MW Battery Energy Storage System was implemented to help balance power grid frequency in November 2014. Ulteig provided engineering services to accommodate the new BESS, which was located at a large wind energy center, including an additional 34.5kV position added to an existing 34.5/138 kV collector substation. The added position was made via a 1200A, 34.5kV breaker with metering class CTs and corresponding bus and line switches. The BESS branches were connected with medium voltage underground cable. Ulteig also provided project services supporting integration of controls and protections schemes, as well as an ION meter included for frequency monitoring.
