Operational mechanism of user-side energy storage in cloud energy storage mode: the operational mechanism of user-side energy storage in cloud energy storage mode determines how to optimize the management, storage, and release of energy storage resources to reduce user costs, enhance sustainability, and maintain grid stability.
Energy storage technologies can effectively facilitate peak shaving and valley filling in the power grid, enhance its capacity for accommodating new energy generation, thereby ensuring its safe and stable operation 3, 4.
The power curve of the grid-connected point is smoothed by controlling the charge and discharge power of the energy storage, and the power fluctuation of the grid-connected point is included in the costs in the form of a regularization function. The regularization function C4 can be expressed as:
With the new round of power system reform, energy storage, as a part of power system frequency regulation and peaking, is an indispensable part of the reform. 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.
The energy storage is configured based on the load data for a total of one year from 1 December 2019 to 30 November 2020. Based on the load characteristics of the example in this paper, energy storage only participates in energy scheduling during working days. There are a total of 252 working days in the selected configuration of energy storage.
First, we build an energy storage configuration optimization model based on the user’s one-year historical load data to optimize the rated power and capacity of the energy storage, and then calculate the costs and benefits of energy storage, and make a judgment on whether the user is suitable for additional energy storage.
