A source-grid-load integrated economic dispatch method and system considering demand response

Abstract

The present invention provides a source-grid-load integrated economic scheduling method and system considering demand response, constructs a source-grid-load integrated economic dispatch optimization model considering demand response and grid topology adjustment, and optimizes the model based on power generation cost and demand response cost The goal is to minimize the total cost of abandoning wind power; convert the mixed integer nonlinear constraints in the optimization model into equivalent mixed integer linear constraints, and use the mixed integer linear programming method to solve the converted mixed integer linear programming model, and get The final integrated economic dispatching scheme of source, network and load. The invention can be used for the economic dispatch of the power system under large-scale wind power grid-connected, and considers the power grid structure on the transmission side and the load demand on the power consumption side as flexible resources that can participate in the dispatch and integrates them into the power generation dispatch plan to realize the overall situation of source, network and load resources Optimal configuration can reduce wind power curtailment and improve the economy of system operation.

Description

technical field [0001] The invention relates to the technical field of power grid dispatching, in particular to a source-network-load integrated economic dispatching method and system considering demand response. Background technique [0002] Vigorously developing new energy is an inevitable choice to solve the current shortage of fossil energy and environmental pollution. Among new energy power generation technologies, wind power technology is the most mature and has the most value for large-scale development, and wind power has shown a trend of large-scale development worldwide. With the rapid development of social economy, the electricity load continues to increase, the peak load continues to climb, and the peak-to-valley difference continues to increase. In addition, affected by natural factors, wind power generation has obvious anti-peak characteristics, that is, the wind power output is low during the daytime peak load period, and the wind power output is high during ...
