A day-ahead scheduling method for wind power consumption considering price-based demand response and participation of CSP power plants

Abstract

The present invention relates to a day-ahead scheduling method for wind power consumption that takes into account price-based demand response and participation of CSP power plants. Aiming at the serious problem of wind power curtailment caused by the weak regulation ability of the existing power grid and the single price mechanism of the electric power market, the present invention considers comprehensive costs Under the premise, taking into account the uncertainty of wind power forecasting and price-based demand response and system security constraints, a dispatch model based on CSP power stations and price-based demand response participating in wind power consumption is constructed. This model combines CSP power stations and price-based demand response The two are combined with wind power optimal dispatching, and the ability of the system to accommodate wind power is jointly improved through the coordinated dispatching of both sides of the source and load. The method of the present invention provides a reference for grid dispatchers, and has scientific and reasonable methods, strong applicability, and good effects. advantage.

Description

technical field [0001] The invention relates to a day-ahead dispatching method for wind power consumption taking into account price-type demand response and participation of CSP power stations. Background technique [0002] Northwest my country is rich in wind, solar and other renewable energy sources, and "multi-source complementarity" has become the main feature of the local new energy power system. However, due to the combined influence of technical and policy factors such as strong wind power volatility, weak grid regulation capability, low load level, and the current single price mechanism in the electricity market, the phenomenon of wind curtailment is becoming more and more serious. How to take into account the technical and market factors, reduce the curtailed wind power and improve the wind power consumption level is a practical problem that needs to be studied and solved urgently in the power system with large-scale wind power. [0003] By strengthening the demand...
