Operation method of distributed energy storage power station participating in power-assisted service market

Abstract

According to the operation method of the distributed energy storage power station participating in the electric power auxiliary service market, the system adopted by the method is suitable for power grid coordination management. The electric energy transaction platform in the system is based on a B / S architecture, has the advantages of a multi-channel transaction function, high transaction speed and low delay, and the HyperLedger Fabric block chain subsystem in the electric energy transaction platform is low in power consumption and modular, so that free open transaction of distributed energystorage can be realized. Two-stage deployment of power grid resource unified scheduling distribution and multi-node platform transaction cooperation is adopted, and aiming at different requirements ofauxiliary service providers of a scheduling system of a power grid company and a distributed energy storage system, the power grid company and the distributed energy storage auxiliary service provider are organically combined through a transaction mode of a block chain; according to the auxiliary decision-making method, an auxiliary service optimization scheme can be formulated for a distributedenergy storage auxiliary service provider in time, and the yield of the distributed energy storage system participating in the power grid is maximized.

Description

Technical field: [0001] The invention relates to a control method for a large-capacity energy storage power station participating in an electric auxiliary service market, belonging to the field of electric power market. Background technique: [0002] Since the first batch of 101MW / 202MWh grid-side energy storage projects in Jiangsu Province were put into operation in July 2018, Henan, Hunan, Gansu, Liaoning and other provinces have actively built large-capacity electrochemical energy storage power stations to solve peak-shaving and frequency-regulation, system Backup, meet the grid peak load and other issues. As of April 2019, my country's grid-side energy storage power stations had an installed capacity of 261,800 kilowatts and a capacity of 422,800 kilowatt-hours, accounting for 46.7% of installed capacity and 29.2% of capacity, exceeding the installed capacity of electrochemical energy storage on the user side. . [0003] The Northeast region allows electric energy stora...
