Embodiment Construction
[0049] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.
[0050] like figure 1 and figure 2 As shown, it is a schematic diagram of an embodiment of a method for predicting an aggregated bidding curve in the peak regulation market of a virtual power plant provided by the present invention. In this embodiment, the method includes the following steps:
[0051] Obtain the virtual power plant operation data to be predicted and the bidding curve data of the virtual power plant peak shaving market to be predicted; specifically, the virtual power plant operation data includes at least the revenue from the purchase and sale of electricity of the virtual power plant, the revenue of the virtual power plant in the peak shaving market, The dispatching cost of virtual power plant regulating electric vehicles and the dispatching ...

The invention provides a prediction method for a peak regulation market aggregation bidding curve of a virtual power plant, and the method comprises the steps: obtaining to-be-predicted virtual power plant operation data; inputting a preset deterministic model for prediction to obtain a virtual power plant income prediction value; determining a virtual power plant benefit threshold value of each segment in a preset segmentation standard; when the virtual power plant benefit threshold value of the segment is smaller than the virtual power plant benefit prediction value, performing constraint through a preset robust model to obtain a first prediction value; when the virtual power plant benefit threshold value of the segment is smaller than the virtual power plant benefit prediction value, performing constraint through a preset opportunity model to obtain a second prediction value; and combining the plurality of first predicted values and the plurality of second predicted values to obtain a final predicted value of the virtual power plant peak regulation market aggregation bidding curve. According to the method, the prediction error of the peak regulation market clearing price of the virtual power plant is considered, and the blank of the current virtual power plant peak regulation market bidding construction technology is filled.
Description
technical field [0001] The invention relates to the technical field of power system automation, in particular to a method for predicting an aggregated bidding curve in the peak regulation market of a virtual power plant. Background technique [0002] At present, the penetration rate of renewable energy is increasing. In order to improve the power grid regulation capability, there is an urgent need for peak regulation and frequency regulation resources. Virtual Power Plant (VPP) has strong flexibility in effectively regulating internal distributed energy resources, and can be used as an emerging peak and frequency regulation resource. Therefore, all parts of my country have also promulgated market mechanisms to encourage virtual power plants to participate in the peak shaving market, making it clear that virtual power plants can participate in the peak shaving market as a third-party independent entity. [0003] Therefore, in order to participate in the peak shaving auxiliar...
