Novel deviation electric quantity assessment mechanism optimization design method based on PBR

Abstract

The invention discloses a novel deviation electric quantity assessment mechanism optimization design method based on PBR. According to the method, a novel assessment unit price piecewise linear deviation electric quantity assessment mechanism based on a PBR (performance assessment mechanism with a reward and punishment mechanism) is provided; a double-layer optimization model of deviation electricquantity assessment mechanism key parameter design is constructed by cooperatively considering the goals that an electric power transaction center maintains balance account stability and an electricity selling company pursues maximization of electricity purchasing and selling profits and risk comprehensive utility. An adjustable load is used as a measure for an electricity selling company to dealwith deviation assessment; based on the psychology of a user, the intention of the user for responding to economic incentives of an electricity selling company is simulated, an actual calling strategy for interruptible loads of the user under a deviation assessment mechanism is researched from the perspective of loss avoidance of the electricity selling company, and on this basis, an optimal operation decision model of the electricity selling company under renewable energy allocation is established. The method plays an important role in stimulating an electricity selling company to improve the load prediction precision and reduce the system deviation rate.

Description

technical field [0001] The present invention relates to the technical field of electric power market, more specifically, relate to a kind of optimization design method of the novel deviation electric quantity assessment mechanism based on PBR. Background technique [0002] At present, most provinces and cities in my country have not yet established a power spot market. At this stage, they mainly carry out medium and long-term transactions with a trading cycle of more than a year, a month, and a week, and take the electricity for a period of time as the transaction target. The transition from the supply-demand balance of the market to the physical balance of the system is carried out by the preparation of the dispatch plan and real-time regulation, and the deviation between the actual power generation and consumption and the contract power is inevitable. [0003] The mid- and long-term market transaction rules for electric power promulgated by various provinces and cities in ...
