A load management method, device and readable storage medium of a grid-connected microgrid

Abstract

The invention belongs to the technical field of electric power dispatching and management, and discloses a load management method, equipment and readable storage medium of a grid-connected microgrid. For important loads, transferable loads, electric vehicle charging loads, interruptible loads and other loads; Step 2, according to the power consumption curves of various loads, establish load power consumption models for various loads; among them, the power consumption models of electric vehicle charging loads The electric curve is obtained by the Monte Carlo algorithm; step 3, establish the load management adjustment target of the grid-connected micro-grid, adjust and control different types of loads according to the load management adjustment target of the grid-connected micro-grid and the load power consumption model of various loads, and complete the grid-connected micro-grid load management. Through load classification and modeling, different load classification forecasting and classification scheduling are realized. According to the load characteristics of electric vehicles in the micro-grid, electric vehicles are dispatched to participate in the overall energy management of the micro-grid, and the economic benefits of the micro-grid 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...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the above-mentioned prior art in the load management of the grid-connected micro-grid that contains the charging load of electric vehicles, because the charging and operation rules of electric vehicles cannot be accurately monitored and collected, and it is impossible to provide various energy management required in the micro-grid. Item parameters, resulting in a deviation between the entire optimization strategy and the actual situation, leading to the disadvantage of low efficiency of the entire grid-connected microgrid, providing a load management method, equipment and readable storage medium for the grid-connected microgrid
