A microgrid energy control method and microgrid system

Abstract

The present application provides a microgrid energy control method and a microgrid system, separating a control flow and a data flow of the microgrid system to improve the stability and real-time performance of the microgrid system energy control. A method for implement an embodiment of that present application includes the follow steps: an area energy controller obtains device operation data andenergy control relate strategy data of an intelligent device in the area; The area energy controller sends the equipment running data to the energy management monitor, and sends the energy control related strategy data to the center energy controller. The central energy controller receives energy control related strategy data for each of the area energy controllers. The central energy controller generates the energy control commands of each area energy controller according to the energy control related strategy data, and generates the energy control commands of each area energy controller according to the energy control related strategy data. The central energy controller sends an energy control command to the corresponding area energy controller. The area energy controller receives the corresponding energy control instruction and adjusts the energy of the intelligent device according to the energy control instruction.

Description

technical field [0001] The present application relates to the field of energy, and in particular, to a microgrid energy control method and a microgrid system. Background technique [0002] With the prominence of global energy and environmental problems, renewable energy such as wind energy and solar energy has been greatly developed. Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, related loads, monitoring and protection devices. The power sources in the microgrid are mostly distributed power sources with small capacity, that is, small units with power electronic interfaces, including micro gas turbines, fuel cells, photovoltaic cells, small wind turbines, and energy storage devices such as supercapacitors, flywheels, and batteries. They are connected to the user side and have the characteristics of low cost, low voltage and low pollution. The microgrid has flexib...

Problems solved by technology

[0004] However, if there are too many smart devices connected in the centralized control mode, the information to be monitored will increase, and the existing controllers have limited information processing capabilities, which will not be able to meet the expansion of installed capacity; It can solve the problem of expansion of installed capacity, but due to the scattered nodes of regional controllers, there is a delay in the transmission of control commands, resulting in poor real-time performance and unstable control
