BESS life span evaluation in terms of battery wear through operation examples of BESS for frequency regulation

Recently the application of frequency control using Battery Energy Storage System(BESS) has gained research interest due to the benefits of BESS. As such electric companies such as Korea Electric Power Corporation(KEPCO) has adopted this in their operation schemes. Most researches pertaining battery life assessment techniques do not take into account factors that cause deterioration. In this paper, we estimate battery life from the viewpoint of capacity through operational data of BESS for Frequency Regulation(FR). Also, the lifetime of the BESS is evaluated considering wear. The wear cost of each operation mode is derived by introducing a Wear Density Function reflecting factors of C-rate, temperature, and DOD.
