Distributed power grid energy regulation and consumption system based on electric vehicle

Abstract

The invention provides a distributed power grid energy regulation and consumption system based on an electric vehicle, and belongs to the technical field of intelligent power grids. The system comprises composite charging and discharging piles, the electric vehicle and a power grid control center; and the plurality of composite charging and discharging piles distributed everywhere of the power grid are combined to form the power grid energy regulation and consumption system. The system makes, dynamically adjusts and optimizes a charging and discharging control strategy for the electric vehicleaccording to power grid power demands, load prediction information, electricity price changes and user vehicle use plans, carries out discharging operation to provide electric energy for the power grid, carries out charging operation to consume surplus electric energy of the power grid, and achieves the purpose of regulating and consuming the power grid energy. An electricity price lever and thepower grid regulation and control information are utilized, more electric vehicle users are attracted and encouraged to access spontaneously, so regulation of power grid energy and consumption of newenergy are carried out, the power grid energy is balanced, and the operation efficiency and stability of the power grid are improved; the users obtain benefits, the win-win purpose of the power grid and the users is achieved, and the system is simple in structure, low in cost and high in practicability.

Description

technical field [0001] The invention relates to an electric vehicle-based distributed grid energy regulation and consumption system, which belongs to the technical field of smart grids. Background technique [0002] At present, China has surpassed the United States to become the world's largest oil consumer. The fuel consumption of motor vehicles in our country is huge. Fuel motor vehicles bring convenience to the development of human society and people's lives, but the exhaust gas emitted by fuel motor vehicles causes great environmental pollution. In order to achieve the goals of sustainable development, energy conservation and emission reduction in the transportation industry and the power industry, vigorously developing electric vehicles and their supporting facilities is destined to be the future development trend of my country's motor vehicle industry. Electric vehicles not only achieve zero emissions, no pollution, and low energy consumption, but also drive the devel...

Problems solved by technology

However, electric vehicles are a special load. When electric vehicles are used on a large scale and connected to the grid, due to the high randomness of their charging time, they will have negative impacts on grid loss, power quality, reliability, and stability.

[0003] New energy power generation has the characteristics of low cost, low pollution, and inexhaustibility. The country vigorously promotes new energy power generation for the purpose of achieving sustainable development, but new energy power generation has the disadvantages of discontinuity and randomness. Negative impact on grid security and operation
