Embodiment Construction
[0046] The application will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, but not to limit the protection scope of the present application.
[0047] Such as figure 1 As shown, the first aspect of the present invention relates to an auxiliary decision-making method for power frequency regulation transactions, including steps 1 to 5.
[0048] Step 1: collect the unit specification parameter data to be predicted, historical influence factors of power supply coal consumption, historical environmental data, and system frequency modulation-related data, and preprocess the data.
[0049] In one embodiment of the present invention, Unit 1 with an installed capacity of 350MW in a thermal power plant in Guangdong Province of Guodian can be used as an example for data collection. Through the collection of data in the unit, the electricity price d...

An auxiliary decision-making method for power frequency regulation transactions, including: collecting and preprocessing the unit specification parameters to be predicted, historical influence factors of power supply coal consumption, historical environment, and system frequency regulation related data; Coal consumption of power supply under different conditions, and obtain the frequency regulation cost of the unit under different loads; take the historical cleared electricity price as the target item, and the effective feature item as the input to perform EMD decomposition and generate IMF components, and use the neural network algorithm to train the IMF components. Obtain the forecasted electricity price for the period to be predicted; use the least squares method to construct a comprehensive frequency modulation performance prediction function and frequency modulation mileage prediction function based on the collected data, and solve the comprehensive frequency modulation performance and frequency modulation mileage for the period to be predicted; calculate the forecast deviation and declared price , bid winning results, frequency modulation mileage compensation to form a declaration decision. The prediction result of the invention is accurate, the prediction speed is fast, and the market change can be responded to.
Description
technical field [0001] The present invention relates to the field of electric power marketization, and more specifically, to an auxiliary decision-making method and system for power frequency regulation transactions. Background technique [0002] At present, various regions have successively established electricity trading markets and issued relevant trading rules. In the existing provincial and regional frequency modulation auxiliary service trading markets, in addition to grid-connected power generation units that meet the regulations, third-party auxiliary service providers such as energy storage equipment and power stations are also encouraged to participate in the trading market. The diversification trend of market players not only promotes the market-oriented development of frequency modulation auxiliary services, but also promotes the satisfaction of various market players for the auxiliary decision-making needs of transaction declaration. [0003] At present, the de...
