Electric heating rolling scheduling method and system considering source-load side response under carbon transaction mechanism

Abstract

The invention discloses an electric heating rolling scheduling method and system considering source-load side response under a carbon transaction mechanism. The method comprises the following steps: determining a heat load demand according to a heat supply network model and a heat supply network model constraint condition introduced with a heat sensation coefficient; determining an electrical loaddemand according to a power demand response model and the demand response constraint condition of introducing a power satisfaction factor; establishing a comprehensive energy carbon emission quota model of each set of equipment in a power grid system under a carbon transaction mechanism and a power system constraint condition under a carbon transaction mechanism; based on the thermal load demand,the electrical load demand, the carbon emission quota model and the power system constraint condition under the carbon trading mechanism, establishing an objective function under a carbon trading reward and punishment step by taking the minimum operating cost as an objective; and solving the target function by adopting an electric heating rolling scheduling method and utilizing an optimization algorithm to obtain the optimal output of each unit. According to the invention, while the satisfaction degree of users is improved, the carbon dioxide emission is reduced, and the wind power consumption is improved.

Description

technical field [0001] The invention relates to the field of energy, in particular to an electrothermal rolling scheduling method and system considering the response of the source and the load side under the carbon trading mechanism. Background technique [0002] In the context of continued global warming and increasing concentrations of carbon dioxide in the atmosphere, reducing carbon dioxide emissions is of paramount importance. And as my country vigorously develops renewable energy such as wind power, the proportion of wind power in my country's total power generation is gradually increasing, but there is still the problem of wind abandonment every year. [0003] At present, in dispatching, because the errors of power system, thermal system and wind power forecasting system always exist, the method of electrothermal rolling dispatching can effectively reduce the impact of forecasting errors. At present, the rolling scheduling of the electric heating system is mainly rea...

Problems solved by technology

However, the existing electric heating rolling scheduling does not consider the user's satisfaction in electricity consumption or electricity consumption behavior in actual operation, which sometimes has a great impact on the user's electricity consumption and heat consumption behavior during scheduling.
