面向经济评估的电池储能系统工况特征量嵌入性研究
Embedded research on working condition characteristics of battery energy storage system for economic evaluation
摘要
Abstract
The investment progress of BESS includes 3 parts, initial purchase, operation and replacement. The working conditions will have different effects on the life decay rate of BESS, and then affect the investment process of BESS. So it's necessary to consider the characteristics of the operating conditions in dynamic economic evaluation of BESS. Firstly this paper defines temperature, rate, Depth of Discharge (DOD), the frequency of charge/discharge as condition characteristic parameter of BESS in BESS-oriented economy dynamic assessment. Based on the relationship between condition characteristic parameter and battery life loss, it builds the output model and the cost model of BESS considering the characteristic parameters of the operating condition. Then, based on the Life Cycle Cost (LCC) model and genetic algorithm, it analyzes the necessity and influence of operating conditions on the economic evaluation of BESS. Finally, it carries out example analysis under two operating conditions, i.e. stabilizing the output fluctuation of PV power station and load peak shaving. The necessity of considering the operating condition characteristics in the process of BESS planning is verified. The research will provide theoretical basis and data base for economic evaluation of BESS in the stage of planning.关键词
