Energy sharing alliance flexibility transaction method based on block chain cooperative game

Abstract

The invention relates to the technical field of electric power system operation control methods, in particular to an energy sharing alliance flexible transaction method based on a block chain cooperative game, and provides an energy sharing alliance of multiple block chain nodes including energy storage, multiple microgrids and a superior power grid based on a cooperative game theory. Establishing each block chain node optimization decision model with the maximum payment benefit of each participant in the alliance; and designing a smart contract based on a multi-target whale algorithm as a nested algorithm and a block chain data hierarchical framework suitable for transactions among multiple block chain nodes. Under the energy decentralized transaction of the cooperation mode, compared with the centralized transaction of the non-cooperation mode, the benefits of the participants in the energy transaction are obviously improved, and the fair and transparent transaction among the participants is ensured under the energy sharing mode; meanwhile, the decentralized cooperative transaction mode can give full play to the initiative of the demand side participating in scheduling, improves the utilization rate of the energy storage system, and promotes the effective utilization of energy and the sustainable development of a sharing mechanism.

Description

technical field [0001] The invention relates to the technical field of power system operation control methods, and relates to a flexible transaction method of an energy sharing alliance based on blockchain cooperation games. Background technique [0002] Accelerating carbon peaking, achieving carbon neutrality, and accelerating structural reforms on the energy supply side not only have a major responsibility for reducing carbon emissions from fossil fuels such as coal power, but also have the mission of vigorously developing new energy sources such as wind power and photovoltaics. Under the urgent requirements of the "30·60" target, the proportion of new energy installed capacity will increase greatly, changing the power structure of the traditional power system, resulting in the continuous increase of pressure on power grid peak regulation and frequency regulation. [0003] Energy storage has fast peak-shaving and frequency-regulating capabilities. It is one of the effectiv...

Problems solved by technology

However, as a new business model, energy sharing also faces new difficulties in the process of comprehensive promotion. For example, there must be trust issues among participants, and the fairness and transparency of transactions between participants cannot be guaranteed.

The traditional centralized energy trading method increases the risk of transaction data being tampered with, directly threatening the security of transaction data and the interests of transaction parties

On the other hand, the number and types of participating subjects involved in the alliance are numerous, and different subjects have the right to choose and make decisions, and play different roles in energy transactions. bring challenges
