Pumped storage unit operation strategy model building method based on electric power spot market

Abstract

The invention discloses a pumped storage unit operation strategy model building method based on an electric power spot market, and the method comprises the steps: obtaining a clearing rule of the spotmarket or a pricing rule of the spot market, and determining a clearing mathematic model of a virtual spot market; acquiring historical quotation data of spot market rules and supervision regulations, and analyzing the historical quotation data to obtain a historical quotation data analysis result; obtaining and analyzing historical clearing data of the spot market, and obtaining a typical constraint scene and a unit constraint condition; determining an optimized quotation window of the pumped storage unit in real time in a preset period, and predicting a load and a system state of the optimized quotation window in preset time; and combining the clearing mathematical model, the historical quotation data analysis result, the typical constraint scene and unit constraint condition, the loadand the system state in the preset time, and determining the operation constraint condition of the pumped storage unit to construct an optimized quotation model of the pumped storage unit.

Description

technical field [0001] The invention relates to the technical field of unit operation optimization, in particular to a method for establishing an operation strategy model of a pumped storage unit based on an electric power spot market. Background technique [0002] With the deepening of power system reform and the increase of trading products in the power market, the market operation strategy of generating units must also be changed accordingly, and the market operation benefits should be maximized under the premise of satisfying market rules and operation constraints. The pumped storage unit has the ability to quickly and flexibly respond to system events, adjust both sides of supply and demand, reduce the peak-to-valley difference of the system, and smooth the system demand curve. Especially, when the system has many units with long start-stop cycle and poor variable output capacity, such as nuclear power, traditional coal power units, or the system has many power sources ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a method for establishing an operation strategy model of a pumped storage unit based on the electric power spot market. Through the clearing rules or pricing rules of the spot market, the clearing mathematical model is determined, and the market price is calculated by combining historical quotation data and clearing data. Carry out analysis and processing, and embed the market price factor into the unit operation strategy model to solve the technical problem that the existing technology does not take the price as an internal variable for the optimization of the pumped storage unit, so as to internally embed the dispatching process into the pumped storage unit In the optimal decision-making model for maximizing economic benefits, the maximization of economic benefits for the operation strategy of pumped storage units is realized
