Multi-target bilateral matching method in medium-and-long-term power market

Abstract

The invention discloses a multi-target bilateral matching method in a medium-and-long-term power market. The method comprises the steps of obtaining quotation and reporting data of a market subject inmarket transaction; constructing a multi-objective matching model by maximizing social welfare, promoting maximization of new energy consumption and promoting maximization of market transaction electric quantity; constructing a market matching constraint condition; and obtaining a Bellman equation by using a dynamic planning method, finally obtaining an optimized matching result through calculation of the simplified target function, and performing pairing transaction clearing on users participating in the market according to the matching result. The social welfare of market transaction, the transaction amount of the market and the new energy consumption amount of the market are considered at the same time, the operation risk of the market is reduced, and the efficiency of the market is improved.

Description

technical field [0001] The invention belongs to the field of electric power technology, and in particular relates to a multi-objective bilateral matching method under the medium and long-term electric power market. Background technique [0002] With the advancement of my country's electricity market reform, more and more provinces and cities have begun to carry out electricity market transactions. At present, bilateral transactions in the medium and long-term electricity market mainly involve direct off-site negotiations between buyers and sellers to determine the transaction quantity, transaction curve and transaction price. After the security inspection, the two parties signed a bilateral transaction contract to complete the agreement. Bilateral transaction modes of electric energy can be roughly divided into two classification methods. First, according to the initiator of the transaction, it can be divided into two types: government-led agreement transaction and enterpri...

AI Technical Summary

Problems solved by technology

However, with the continuous development of market-oriented transactions, the number of bilateral transaction entities will increase, and it will be difficult for transaction entities to select transaction partners that meet market needs

[0004] On the other hand, under the traditional bilateral electricity market transaction rules, the market entities participating in bilateral transactions conduct transactions through free negotiation, information is blocked, transactions cannot maximize social welfare, and the counterparty that the transaction entities are looking for is not necessarily the optimal solution.
