Embodiment Construction

[0045]There are many traditional studies on wind-fired bundling, but the research angles are different. Some consider the optimal wind-fired capacity allocation under different operating modes of wind-fired bundling, some propose planning methods for wind-fired power plants, and others Theoretical Calculation Method for Optimal Capacity of Fire Bundled Power Plant. The above studies all considered the planning of wind-fired power plants, but there are not many research results on wind-fired power plants participating in power market transactions. Therefore, it is necessary for the present invention to propose a decision-making method for wind-fired power plants participating in the medium and long-term power market. of.

[0046] The invention provides a decision-making method for optimal contract power of a wind-fired bundled power plant in a mid-to-long-term power market. Based on the principle of optimal benefit of a wind-fired bundled power plant, it can provide valuable ad...

Abstract

The invention discloses an optimal contract electric quantity decision-making method for a wind-fire bundling power plant in a medium-and-long-term power market. The optimal contract electric quantitydecision-making method comprises: obtaining basic technical parameters, system operation constraint condition data and historical transaction prices of a wind-fire bundling system; establishing an optimization target by taking maximization of the benefit of the wind-fire bundling power plant as a target function; constructing a system operation constraint condition, and establishing a maximum benefit model; inputting the obtained system basic technical data, system operation constraint condition data and historical transaction prices into a constructed optimization model, and solving to obtain optimized wind power bidding electric quantity and thermal power bidding electric quantity; and feeding back the obtained optimal contract electric quantity calculation result to the power plant, and making a decision on electric quantity bidding of the wind-fire bundled power plant. The optimal contract electric quantity and the historical average transaction price obtained by the method are adopted to sign a medium-and-long-term electric power contract with a user or an electricity selling company so as to obtain the maximum benefit.

Description

technical field [0001] The invention belongs to the technical field of power supply, and in particular relates to a decision-making method for optimal contract power of a wind-fired bundled power plant in a mid-to-long-term power market. Background technique [0002] In the new era, power producers no longer only use fossil energy as their main production energy, but new energy sources such as wind power and photovoltaics are also involved. Vigorously developing wind energy resources is of great significance for the rapid development of energy demand, the realization of energy conservation and emission reduction goals, and the control of air pollution. However, due to the uncertainty and intermittency of wind power generation, supplying power to the receiving end system solely through wind power generation will lead to difficulties in peak regulation and voltage instability. In order to make full use of the advantages of wind resources and reduce the impact of pure wind pow...
