Abstract

The invention discloses a microgrid power supply system and a microgrid power supply method. The microgrid power supply system comprises a control system, an electrical quantity detector, a power supply system and at least one electric vehicle, wherein the electrical quantity detector is used for detecting electrical quantity of a battery of the electric vehicle, electricity utilization power of electricity utilization equipment and an output power of the power supply system and sending power information, the control system is used for receiving the power information and controlling charging or discharging of the electric vehicle and the power supply system, and the electric vehicle is used for supplying power to the electricity utilization equipment when the output power of the power supply system is smaller than the electricity utilization power of the electricity utilization equipment, and receiving electric energy of the power supply system to charge the battery when the output power of the power supply system is larger than the electricity utilization power of the electricity utilization equipment. By the technical scheme, the battery of the electric vehicle is effectively utilized, so that a microgrid is more flexible and variable in power supply.

Description

technical field [0001] The invention relates to the technical field of micro-grid power supply, in particular to a micro-grid power supply system and a micro-grid power supply method. Background technique [0002] Microgrid refers to a small power generation and distribution system composed of distributed power sources, energy storage devices, energy conversion devices, loads, monitoring and protection devices, etc. An efficient way for the grid. With the promotion of electric vehicles and the development of technology, more and more electric vehicles need to be connected to the grid for charging and discharging. From the perspective of energy storage, electric vehicles are essentially a kind of battery energy storage. It has the characteristics of sufficient scheduling resources, flexible adjustment methods, fast response speed and distributed distribution. However, the existing microgrid technology fails to make good use of the batteries of electric vehicles. When a lar...
