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 power decision-making method for a wind-fired bundling power plant in a mid-to-long-term power market, which obtains the basic technical parameters of the wind-fired bundling system, data on system operating constraints and historical transaction prices; and maximizes the benefits of the wind-fired bundling power plant Establish an optimization goal for the objective function; construct system operating constraints and establish a maximum benefit model; input the obtained system basic technical data, system operating constraint data, and historical transaction prices into the optimized model to solve the optimized wind power bidding Power and thermal power bidding power; Feedback the calculation results of the optimal contract power to the power plant, and make a decision on the power bidding of the wind-fired power plant. Using the optimal contract power and historical average transaction price obtained in the present invention to sign medium and long-term power contracts with users or power sales companies, so as to obtain maximum benefits.

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...
