[0068] See figure 1 , the first embodiment of the present invention provides a dynamic quotation decision-making method for members on the power generation side, which at least includes the following steps:

[0069] S1. Generate the reinforcement learning initial strategy space of each power generation member according to the input power market transaction information, and initialize the selection probability of each bidding strategy in the initial strategy space;

[0070] In one of the possible implementation methods, since power generation members generally use segmented quotations, the number of segments of the quotation function will be limited, and the quotation will also be limited by the price cap; at the same time, the declared capacity needs to meet the maximum output and minimum output of the generating set limit.

[0071] Therefore, in order to have unity when generating the strategy space for each generation member Agent, this embodiment assumes that each Agent ad...

[0129] The second embodiment of the present invention also provides a dynamic bidding decision-making device for power generation members, which is used to implement the dynamic bidding decision-making method for power generation members provided in the first embodiment of the present invention. The power generation bidding device may include at least one of the following items: Terminals, computers (PCs), servers, etc. include:

[0130] The information input module is used to acquire electricity market transaction information, the electricity market transaction information includes open market information, historical transaction data, quotation data of each generating set, and clearing results after information screening and transformation;

[0131] The reinforcement learning initial strategy space generation module is used to generate the reinforcement learning initial strategy space of each power generation member according to the input power market transaction information;...

Abstract

The invention discloses a power generation side member dynamic quotation decision-making method, device and equipment, and the method comprises the steps: S1, generating a reinforcement learning initial strategy space of each power generation member, and carrying out the initialization of the selection probability of each quotation strategy; S2, selecting a quotation strategy with the maximum selection probability; S3, utilizing the clearing model to obtain a market clearing result; S4, generating a local optimal strategy space based on a diagonalization optimization mechanism; S5, calculatingan evaluation function value of each quotation strategy through a reinforcement learning method, and correcting a selection probability of the quotation strategy; S6, when the reinforcement learningtermination condition is not met, executing the step S2 again; and S7, when it is judged that the evaluation function value meets the reinforcement learning termination condition, outputting an optimal quotation strategy. According to the method, the problem that a clearing result deviates from a Nash equilibrium point in the Nash equilibrium market is solved, and meanwhile analysis on market power generation members is introduced, so that the method is closer to the real decision process of the market power generation members.

Description

technical field [0001] The present invention relates to the technical field of electric power market, in particular to a dynamic quotation decision-making method, device and equipment for power generation side members. Background technique [0002] The centralized bidding market will be cleared every day, and market members will accumulate a lot of information in the transaction, which provides conditions for power generation members to continuously try to quote. In the day-ahead market, power generation members will constantly adjust their quotation strategies based on historical quotations and earnings. For the simulation of electricity market transactions, on the one hand, it is necessary to establish a centralized bidding clearing model to simulate the market clearing process; affect the market equilibrium as a whole. [0003] Each generation member is differentiated. When using the Multi-Agent structure to model the generation member, the core is to study the quotatio...
