Customer ServiceIn , the economic value of user side energy storage is considered in reducing the construction of user distribution stations and the cost of power failure losses. In , the benefits and life cycle costs are considered brought by price arbitrage, demand management and energy storage life cycle of industrial users.
The electrical energy supplied by the energy storage device is shown in Table 2. This time, the distribution network's power demand is 675 kWh. The details of the online bidding process for energy storage devices are presented in Table 3.
The configuration of user-side energy storage can effectively alleviate the timing mismatch between distributed photovoltaic output and load power demand, and use the industrial user electricity price mechanism to earn revenue from peak shaving and valley filling.
In [ 86 ], the impact of an energy storage system’s capacity on the economy of the whole life cycle of the system was studied to minimize the total cost of the system, including grid power supply costs, photovoltaic power generation costs, and battery charging and discharging depreciation costs.
The energy storage life is also determined by the actual operation strategy of energy storage; and in order to determine the operation strategy of energy storage, the configuration capacity of photovoltaic and energy storage must be given first.
Among them, user-side small energy storage devices have the advantages of small size, flexible use and convenient application, but present decentralized characteristics in space. Therefore, the optimal allocation of small energy storage resources and the reduction of operating costs are urgent problems to be solved.
