Abstract

The invention belongs to the technical field of power grid energy storage, and specifically relates to a centralized cloud energy storage system, a transaction settlement method thereof, a storage medium and a terminal. The centralized cloud energy storage system comprises a centralized energy storage facility which is invested and operated by a cloud energy storage service provider, massive distributed users, a power network and a user energy management system, wherein the power network and the user energy management system are used for connecting the centralized energy storage facility and the massive distributed users; a user sends charging and discharging requests to the cloud energy storage service provider through the user energy management system; and the cloud energy storage service provider issues charging and discharging instructions to the centralized cloud energy storage system. The transaction settlement method comprises the steps that a cloud energy storage service provider provides a cloud energy storage service for a user, and the user sends a request to the cloud energy storage service provider; the cloud energy storage service provider issues charging power and discharging power instructions to the centralized energy storage facility; and settlement of the operation cost is carried out between the cloud energy storage service provider and the user and the power grid. The storage medium and the mobile terminal are used for realizing the transaction settlement method.

Description

technical field [0001] The invention belongs to the technical field of power grid energy storage, and in particular relates to a centralized cloud energy storage system for massive distributed users, a transaction settlement method, a storage medium and a terminal. Background technique [0002] With the promotion of distributed power generation technology and real-time electricity prices, users are increasingly hoping to invest in energy storage devices so that they can independently choose the timing of charging and discharging to achieve the purpose of reducing electricity costs. Users investing in local physical energy storage devices may face high unit costs, and also need to spend a certain amount of energy on maintenance. It is a better alternative to replace the user's local physical energy storage device with shared cloud virtual energy storage. Cloud energy storage service providers can achieve economies of scale through large-scale investment in the construction o...
