Abstract

This application discloses a source-network-load-storage coordination method and system, specifically: the network controller calculates the power coordination capability of the client-side energy storage unit according to the current state parameters of the client-side energy storage unit, and The power coordination capability of the energy unit is sent to the coordination service system. According to the power coordination target corresponding to the network topology node where the client-side energy storage unit is located and the power coordination capability of the client-side energy storage unit, the coordinated service system generates a coordinated response command corresponding to the client-side energy storage unit, and sends the coordinated response command sent to the network controller. When the network controller determines that the subsidized electricity price carried by the cooperative response instruction exceeds the market electricity price, it adjusts the power of the client-side energy storage unit according to the power adjustment plan value of the client-side energy storage unit carried by the coordinated response instruction. This can reduce the difficulty of realizing the energy storage unit on the customer side to participate in the peak regulation of the power grid, and improve the response efficiency.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a source-network-load-storage coordination method and system. Background technique [0002] With the development of clean energy (eg, renewable energy), the energy structure is gradually changing. However, with the intensification of grid regulation pressure, the intermittent power generation of renewable energy and the load peak-valley effect are also intensified accordingly, resulting in greater pressure on grid peak regulation and increased difficulty in dispatching work. [0003] However, how to effectively reduce the pressure of power grid peak regulation and the difficulty of dispatching work is still a technical problem to be solved urgently. Contents of the invention [0004] In order to solve the above technical problems existing in the prior art, the present application provides a source-network-load-storage coordination method and system, which can e...
