Abstract: Firstly,the principles to be followed for energy storage optimization were given,and then the optimal energy storage configuration was studied from the two aspects of energy storage configuration model optimization and operation optimization.In view of the economic benefit evaluation of energy storage project,the energy storage cost model and benefit model were established respectively.By analyzing the impact of energy storage charge and discharge times and charge and discharge depth on the energy storage life,the peak-load and frequency-modulated operation benefit models were presented.Based on one industrial park energy storage project,the economic analysis of three kinds of battery energy storage system was carried out.The results show that under the condition of energy storage technology at present,all kinds of the cost of battery energy storage system are relatively high.The user-side battery energy storage system investment income in the short term is not obvious.But for the whole life cycle of energy storage system after operation,each income is quite remarkable.
