A method for power system dispatching based on source-load interaction

Abstract

This application provides a power system scheduling method based on source-load interaction, which fully considers the influence of electricity price factors, not only considers the decision-making unit combination, but also maximizes social welfare. In this model, wind power output is assumed to be certain, and the price elastic demand curve is also certain. At the same time, the electricity demand in each time period includes elastic demand and inelastic demand, but the electricity demand in the consumer surplus of the objective function is only elastic demand, and the consumer surplus of inelastic demand is 0. The mathematical model constructed in this way can fully reflect the actual demand response of users; and in the process of determining the objective function constraints, in addition to ensuring that the power system can operate safely and reliably, and the decision variables meet some conventional constraints, the post-demand response is also considered. Constraint conditions, so that the model can better reflect the actual situation, provide an accurate basis for later scheduling decisions, and use the order optimization algorithm to solve the model, greatly reducing the amount of calculation.

Description

technical field [0001] The present application relates to the technical field of power grid control, in particular to a method for dispatching a power system based on source-load interaction. Background technique [0002] With the large-scale development and utilization of hundreds of years since the industrial revolution, the fossil energy of the transmission is facing practical problems such as resource depletion and serious pollution emissions. At the same time, environmental pollution and climate change have also seriously affected the sustainable development of human beings. The way of energy production and consumption based on fossil energy needs to be changed urgently. At the same time, the world's intermittent new energy power generation represented by wind energy and solar energy is generally in a stage of accelerated development. [0003] However, the basic feature of the power system is to ensure the balance of energy supply and demand. In the traditional dispatc...
