The embodiment of the invention provides an electricity utilization optimal collocation method and system. The electricity utilization optimal collocation method comprises the steps that with economic benefits being the target, an objective function is established according to preset constraint conditions, and a linear electricity utilization optimization model is obtained; an electric power system is divided into a system layer, a transformer substation layer, a feeder line layer and a user layer, and a topological relation among the layers of the electric power system is determined; electricity utilization optimal collocation is conducted for all the users in the electric power system according to the linear electricity utilization optimization model, and electricity utilization optimal collocation schemes of the system layer and the user layer in the electric power system are obtained; according to the electricity utilization optimal collocation schemes and the topological relation, electricity utilization optimal collocation schemes of the feeder line layer and the transformer substation layer in the electric power system are obtained in sequence. The electricity utilization optimal collocation method and system have better economy, are simple in calculation and small in calculation amount, thereby improving the efficiency of obtaining the electricity utilization optimal collocation schemes.
Description
technical field [0001] The invention relates to the technical field of electric power engineering, in particular to a method and system for optimizing configuration of electricity consumption. Background technique [0002] At present, with the continuous development of the economy, people's demand for electricity (especially the peak load) is growing very rapidly. In this context, the traditional method of relying on the increase of power generation capacity to meet the growing demand for electricity has been economical and In terms of efficiency, it shows its shortcomings. Not only is the economy low, but after increasing the power generation capacity, the optimal configuration scheme for power consumption in the power system is obtained, which requires a large amount of calculation, and the efficiency of obtaining the optimal configuration scheme for power consumption is low. Contents of the invention [0003] In view of this, the embodiments of the present invention pr...
