Abstract

The invention discloses a wind and light storage intelligent micro-grid economic dispatch control method. The method comprises the steps that 1, related running data is obtained through micro-grid running parameter data; 2, according to meteorological data, short-term power prediction is conducted on a distributed power supply in a micro-grid by means of a time-order character optimization model,and meanwhile a BP neural network model is utilized for conducting short-term power prediction on a load in the micro-grid; 3, on the basis of distributed power supply short-term power prediction, load short-term power prediction and energy storage system stage-of-charge and stage-of-charge threshold value of an energy storage system, and running modes of wind power, photovoltaic power generationand the energy storage system are determined; the purpose that the wind power and photovoltaic power generation can be consumed to the maximum extent is achieved, and meanwhile the technical effect ofbeing good in power quality and economical efficiency is guaranteed.

Description

technical field [0001] The present invention relates to the field of wind-solar-storage smart microgrid, in particular to an economic scheduling control method for wind-solar-storage smart microgrid. Background technique [0002] With the massive emission of greenhouse gases, the pressure on the environment is becoming increasingly severe. Due to the long distance between the load and the power source, a large amount of investment and maintenance is required for the transmission and distribution system through long-distance transmission. At the same time, the loss of long-distance transmission increases, which is not economical. Not environmentally friendly either. As a new type of clean energy, the microgrid can solve the potential problems of the traditional grid due to its proximity to the load center, low environmental pollution, easy installation, and easy control, and has received extensive attention. The purpose of micro-grid economic dispatch is to reasonably arrang...
