Although ESS bring a diverse range of benefits to utilities and customers, realizing the wide-scale adoption of energy storage necessitates evaluating the costs and benefits of ESS in a comprehensive and systematic manner. Such an evaluation is especially important for emerging energy storage technologies such as BESS.
Energy storage systems (ESS) are increasingly deployed in both transmission and distribution grids for various benefits, especially for improving renewable energy penetration. Along with the industrial acceptance of ESS, research on storage technologies and their grid applications is also undergoing rapid progress.
PHES was the dominant storage technology in 2017, accounting for 97.45% of the world’s cumulative installed energy storage power in terms of the total power rating (176.5 GW for PHES) . The deployment of other storage technologies increased to 15,300 MWh in 2017 .
As a promising solution technology, energy storage system (ESS) has gradually gained attention in many fields. However, without meticulous planning and benefit assessment, installing ESSs may lead to a relatively long payback period, and it could be a barrier to properly guiding industry planning and development.
Simulation results have demonstrated that the proposed stochastic model is effective and flexible to optimize ESS size of power systems coupled with various probabilistic uncertain wind generation, and the proposed hybrid PE-BB solution approach is more computationally efficient than the existing day-by-day rolling optimization method.
Results based on real data show that the electricity bill decreases by 12%. An optimal thermostat programming is proposed for customers equipped with a thermal storage system to reduce TOU and demand charges averagely 9.2% over several different building models .
In this article, we present a comprehensive framework to incorporate both the investment and operational benefits of ESS, and quantitatively assess operational benefits (ie, …
