Abstract

The invention discloses an electric power energy management system based on a V2G microgrid system, comprising an energy management control center, a grid-connected power distribution unit, a power distribution PDU unit and an energy storage unit. The power distribution PDU unit is used for being connected with a new energy power supply, an electric load, the grid-connected power distribution unit and the energy storage unit, the grid-connected power distribution unit is connected with a power grid, and the energy management control center is used for sending power utilization information of the electric energy management system to a V2G cloud platform. The electric energy management system takes the energy storage unit as a buffer for electric energy conversion among the new energy power supply, the electric load and the power grid, so that the conversion quantity of alternating current and direct current is reduced, the electric energy loss is reduced, and the advantage conversion quality of the V2G microgrid system in a unit region range is improved.

Description

technical field [0001] The invention relates to the technical field of distributed energy sources, in particular to a power energy management system and method based on a V2G microgrid system. Background technique [0002] At this stage, distributed energy has become a popular energy supply method, which can effectively supplement the power grid and strengthen the use of distributed energy distribution, whether it is to improve the utilization rate of electric energy, reduce the loss of electric energy, or It has great practical significance for resource protection. Compared with centralized power generation, distributed power generation has many advantages. First of all, distributed power generation is a decentralized and small-scale power generation unit, which is often located around the distribution network and loads. At the same time, the power of distributed generation can reach several kilowatts or even hundreds of megawatts. At present, the most common types of di...
