Description

technical field [0001] The invention relates to the field of smart grids, in particular to a power consumption scheduling method capable of reducing the average value of power consumption costs and fluctuations thereof. Background technique [0002] Driven by the awareness of green energy conservation, the flexible supply and demand management system and the full use of renewable energy will become important technologies for the development and improvement of smart grids in the future. [0003] In the traditional power grid, the reliability of the power grid has always been ensured by providing excess power consumption capacity. Therefore, with the continuous increase of user demand, it will be difficult for the power grid to provide sufficient power consumption capacity for future demand. In addition, low-efficiency and wasteful supply and demand management systems are the main source of greenhouse gas emissions and the main source of consumption of fossil fuels, and such s...
