Energy storage energy management system and method based on distributive control mode

Abstract

The invention discloses an energy storageenergy management system and method based on distributive control mode. The system includes an energy management module, a plurality of distributive energy storage sub-systems and distributive energy management sub-modules which correspond to each distributive energy-storage sub-system. Each distributive energy storage sub-system includes an energy storage battery, an energy storage monitoring unit BMS and an energy storage converter PCS. The energy storage battery is connected to a power distribution network system through the energy storage converter PCS. The energy storage monitoring unit BMS is in electrical connection to the energy storage battery. The distributive energy management sub-modules are in separate connection to the energy storage monitoring unit BMS, the energy storage converter PCS, and the energy management module through a communication network. According to the invention, the system herein can control respective energy storage sub-system to work, and addresses the difficulty of real-time control, heavy data, and complex strategies of energy storage power station. The system herein can achieve high efficient maintenance and operation.

Description

technical field [0001] The invention relates to the technical field of energy storage energy management, in particular to an energy storage energy management system and method based on a distributed control mode. Background technique [0002] my country's current power grid operation is facing many challenges such as the continuous increase of the highest power load, the expansion of the proportion of intermittent energy access, and the limited means of peak regulation. High-quality, self-healing, safe, clean, economical, and interactive are the goals set by my country's smart grid. Many characteristics of energy storage technology, especially large-scale energy storage technology, can be obtained in the four major links of power generation, power transmission, power distribution, and power consumption. Widely used, it can be said that the energy storage link is an indispensable key link in building a smart grid and achieving its goals. [0003] Energy storage technology is ...
