Intelligent power grid management system and method

Abstract

The invention discloses an intelligent power grid management system, comprising a battery cabinet, a one-piece controller, a solar energy module, the national power grid, an electric power demand side management module and a battery lifetime extension device. The one-piece controller comprises a charger, an inverter, a control apparatus and an output terminal. The national power grid is in connection with the battery cabinet through the charger to charge the battery cabinet. The national power grid is also in connection with the output terminal through leads; the control apparatus controls the output terminal to be in connection with the national power grid or the inverter. The output terminal is in connection with the electric power demand side management module; the battery lifetime extension device is in connection with the battery cabinet. The management system can optimize the national power grid, and meanwhile introduces the demand side management module to an intelligent power grid which is used for user power supply; saved electric quantity and electricity consumption in each period after using the system can be directly counted, electric charge price difference corresponding with electric charge unit price of each period is obtained, and government sectors award or subsidize users according to price difference.

Description

technical field [0001] The invention relates to a smart grid management system and method. Background technique [0002] With economic and social development, energy demand and environmental costs are increasing. Energy conservation, efficient utilization, development of renewable energy, and construction of green, low-carbon and environmentally friendly ecological cities have become issues facing governments of all countries today. In order to ensure the sustainable development of my country's energy environment, meet the economic and social demand for electricity, and alleviate the tension in power supply, relevant power departments in various places are starting to formulate relevant technical and economic means to encourage users on the power demand side to cut peaks and fill valleys independently. From the perspective of the power sector, making more use of off-peak power can effectively reduce system maintenance costs. Under the condition of having a grid-connected inv...

AI Technical Summary

Problems solved by technology

[0003] In my country, the government department vigorously advocates the demand side management system, and subsidizes enterprises using power demand side management projects through some special funds. The organic combination of self-energy saving and emission reduction can fundamentally solve the problems of power system security and sustainable development.
