This is conducted by taking into consideration the time-of-use electricity price, demand price, on-grid electricity price, and energy storage operation and maintenance costs.
On the one hand, the user-side distributed energy storage device can store electricity through renewable energy sources such as scenery during the day; On the other hand, the energy storage device
User-side energy storage, in simple terms, refers to the application of electrochemical energy storage systems by industrial and commercial customers. Think of these systems as substantial power banks that charge when electricity prices are low and discharge to supply power to companies when prices are high.
It is seen from Fig. 6 that the optimal power and energy of the energy storage system trends in a generally upward direction as both the peak and valley price differential and capacity price increase, with the net income of energy storage over the life-cycle increasing from 266.7 to 475.3, 822.3, and 1072.1 thousand dollars with each successive 10% increase in

3.1 Energy Storage System Model. Considering the battery bank and the user as a whole, the optimization objective is to minimize the overall cost. In this case, the battery bank can make profits through energy arbitrage, such as buying power from the grid when the price of electricity is low, selling power to the grid when the price of electricity is high, or providing
