Contract electricity price formulating method for direct electricity purchase bilateral trade based on leader-follower game

Abstract

The invention discloses a direct electricity purchase bilateral trade contract electricity price formulating method based on a leader-follower game. The method adopts a leader-follower game model to study an optimal contract offer decision of a generation company in direct electricity purchase bilateral trade: first, optical planning models of generation companies and big consumers are built respectively, and then a complete leader-follower game model containing two interested parties of a plurality of generation companies and a plurality of big consumers is built. The method provided by the invention provides a basis for contract electricity price formulation for the generation companiesin a bilateral trade process, and also provides a basis for electricity purchase decision for the big consumers under a determined generation company bilateral contract offer, thereby realizing maximum contract electricity-selling profits of the generation companies and minimum electricity purchasing cost of the big consumers under a determined contract electricity price in bilateral trade with participation of the plurality of generation companies and the plurality of big consumers.

Description

technical field [0001] The invention relates to a method for formulating a contract electricity price, in particular to a method for formulating a contract electricity price based on a master-slave game for direct power purchase bilateral transactions. Background technique [0002] With the deepening of China's electric power reform, the monopoly power grid distribution pattern is gradually being broken. As an important part of my country's electricity market reform, the direct transaction between large users and power generation enterprises is the breakthrough point for bilateral transactions in the electricity market. In the electricity market environment, the existence of the spot market creates opportunities for market participants to obtain higher profits, but this high profit is accompanied by high risks. However, the duration of bilateral contracts is generally longer, and the contract price is determined at the moment the contract is signed. Therefore, bilateral con...

Problems solved by technology

[0004] It can be seen that there is currently no method for formulating contract electricity prices that considers the bilateral transactions between multiple power generators and multiple large users
