Method for reducing cost of wind turbine merchant in power balance market

Abstract

The invention discloses a method for reducing the cost of a wind turbine merchant in a power balance market, which comprises the following steps of: S1, obtaining the relation data of a wind power prediction error and a prediction time scale, and calculating the cost of the wind turbine merchant in the power balance market under the operation structure of the North European power market; S2, analyzing the internal correlation among the prediction error, the prediction time scale and the cost of the wind power merchant in the power balance market, designing a power balance market option transaction mode, and establishing a wind power provider power balance market option transaction risk decision model; and S3, the power market option transaction model is applied to the North European powermarket operation structure, so that the cost of the wind turbine merchant in the power balance market is reduced. The invention provides a method which is simple to implement and capable of avoiding short-term market risks and promoting efficient utilization of electric power resources. The method can effectively reduce the risk cost of a wind turbine merchant in the power balance market.

Description

technical field [0001] The invention relates to the technical field of new energy power systems, in particular to a method for reducing the cost of wind power suppliers in the power balance market. Background technique [0002] The characteristics of electric energy that can be used immediately and cannot be stored in large quantities make the electricity spot market transactions have greater risks. Before a large number of new energy sources are connected to the system, the risks faced by power generators mainly come from power price fluctuations. This risk can be managed in the power financial market through futures contracts, forward contracts, contracts for difference and options. The transaction span includes daily, weekly and quarterly , year, etc. With the penetration of new energy such as wind power, the uncertainty of its output is another major risk faced by power generators. Wind power output forecast deviation will generate high costs in the balancing market (R...

Problems solved by technology

In addition, related data show that in the 24 hours before the actual operation, the wind power forecast uncertainty will be reduced from 15% to 4%

According to the above-mentioned options, wind power output characteristics and the phenomenon of high cost of wind power companies in the balance market, it is of great significance to seek an option auxiliary service model with a time scale of hours to reduce the cost of wind power companies in the power balance market
