Electric heating load regulation optimization method and device

Abstract

The invention relates to an electric heating load regulation optimization method and device. The method comprises the steps of substituting an obtained load distribution amount of an electric heatingload into a load regulation efficiency optimization model, and obtaining a load regulation efficiency initial value of each electric heating load; based on the load regulation efficiency initial valueof each electric heating load, correcting the load distribution quantity of the electric heating loads input into the load regulation efficiency optimization model in the iterative solution process by utilizing a dual model of the load regulation efficiency optimization model, and determining an optimal load regulation scheme according to the load regulation quantity of each electric heating loadobtained in the iterative solution process. The optimal load regulation and control scheme is obtained by optimizing the load regulation efficiency of the electric heating load, and the problems thatthe voltage at the tail end of the power distribution network is low and the load utilization rate is not high due to increase of the electric heating load are solved.

Description

technical field [0001] The invention relates to the technical field of electric power planning and dispatching, in particular to an electric heating load adjustment and optimization method and device. Background technique [0002] Compared with conventional power loads, the energy consumption behavior of electric heating loads often has obvious climate and behavior-driven characteristics, which will have an important impact on the safe operation of distribution networks. With the emergence of new load peaks, the load rate of power grids in many places has touched or exceeded the "warning line", which has brought new difficulties to the construction and transformation of distribution networks; The frequent low-voltage phenomenon brought by the power grid, in severe cases, will even cause troubles for the production of enterprises and the normal electricity consumption of residents. [0003] The application of various types of electric heating load equipment has exposed many ...
