Grid-connected microgrid load management method and device and readable storage medium

Abstract

The invention belongs to the technical field of power dispatching and management, and discloses a grid-connected microgrid load management method and device, and a readable storage medium. The methodcomprises the following steps: step 1, dividing loads in a grid-connected microgrid into an important load, a transferable load, an electric vehicle charging load, an interruptible load and other loads according to the power utilization characteristics of the loads; step 2, establishing load power utilization models of various loads according to the power utilization curves of various loads, wherein the power utilization curve of the charging load of the electric vehicle is obtained through a Monte Carlo algorithm; and step 3, establishing a grid-connected microgrid load management adjustmenttarget, and regulating and controlling different types of loads according to the grid-connected microgrid load management adjustment target and the load power utilization models of various loads to complete grid-connected microgrid load management. Different load classification prediction and classification scheduling are realized through load classification and modeling, electric vehicles are scheduled to participate in microgrid overall energy management according to the load characteristics of the electric vehicles in the microgrid, and the economic benefits of the microgrid are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power dispatching and management, and relates to a load management method, equipment and a readable storage medium of a grid-connected microgrid. Background technique [0002] The microgrid system is a complete system including distributed power supply, energy storage, load and protection system. The energy conversion device in the system is responsible for energy conversion, and the monitoring and protection device monitors and protects the system during the operation of the system. A small power system that can self-protect and control management operation. The grid-connected microgrid refers to the grid-connected operation with the large power grid to realize the maximum utilization of distributed energy. [0003] A single power load in a microgrid often has a small capacity and a large amount of data. The microgrid energy management system directly manages and controls hundreds of power load...
