Abstract

The invention discloses a method and device for information interaction between micro-grids and a large grid. The method comprises the steps that micro-grid attribute information transmitted by all micro-grid energy management systems is received, wherein the micro-grid attribute information comprises active and reactive power input requirements of micro-grid objects, active and reactive power issuing capability and issuing price of the micro-grid objects and input power quality requirements and power quality output conditions of the micro-grid objects; pre-stored grid positions of all the micro-grids, structural parameters of the large grid itself, grid operation security constraints and regional policy constraints are acquired; a large grid model with the optimal benefits of the large grid serving as the target is established by utilizing the micro-grid attribute information and the obtained data; the large grid model is solved, conventional selling electricity price, the micro-grid objects selected by conventional electricity purchase of the large grid and the purchase amount of all the micro-grid objects obtained through solution are transmitted to the corresponding micro-grid energy management systems. According to the method and device, the micro-grids are brought into an electricity trading system of the grid, and therefore the efficiency of energy utilization is improved.

Description

technical field [0001] The present application relates to the technical field of power systems, and more specifically, to a method and device for information interaction between a microgrid and a large power grid. Background technique [0002] The emergence of micro-grid (referred to as micro-grid) integration is one of the future development trends of the power system. Different from the pure electricity load at the traditional power consumption end, the microgrid is a microgrid that can have distributed power generation equipment, energy storage equipment, electric vehicles and loads. Through its own energy management system and small-scale communication network, the microgrid coordinates and controls variable loads, distributed power generation, energy storage equipment discharge, and electric vehicle charging and discharging under its jurisdiction to achieve optimal operation within the microgrid. [0003] At present, the microgrid is connected to the traditional large ...
