Abstract

The invention discloses an energy storage capacity configuration method and device. The method comprises the following steps: constructing a utility objective function of a user according to acquired user load data, two-part electricity price of a local power grid, a power grid transmission capacity upper limit and an energy storage parameter; dividing the cloud energy storage total capacity on the basis of a preset cake cutting game model according to the principle of maximizing the income after the user purchases the cloud energy storage service and by taking the optimal division of the cloud energy storage total capacity as a target function, so as to obtain a Pareto optimal division scheme; and solving the Pareto optimal division scheme based on the variational inequality of the hyperplane projection to obtain the optimal solution of the cloud energy storage total capacity division. The preset cake cutting game model is utilized to describe the division of the total cloud energy storage amount, so that the economic benefit of each user participating in the cloud energy storage market can be maximized under the condition that the total cloud energy storage amount is not exceeded.

Description

technical field [0001] The invention belongs to the technical field of cloud energy storage capacity sharing, and in particular relates to an energy storage capacity configuration method and device. Background technique [0002] In recent years, with the continuous development of distributed energy storage technology, a "wholesale market-energy storage aggregator-user" cloud energy storage transaction model based on a large number of distributed energy storage aggregation technologies has gradually become popular. This form of cloud energy storage transaction allows terminal energy users not to configure energy storage locally, but to purchase energy storage services from energy storage aggregators, thereby cutting peak loads and filling valleys, reducing short-term peak power consumption of users, and improving energy efficiency. user efficiency. [0003] At present, due to the simultaneous purchase of energy storage services by end users in the same region, it is difficul...
