Dividend Redistribution Mechanism and Consensus Algorithm for Joint Clearing in Regional Power Markets

doi:10.16183/j.cnki.jsjtu.2024.364

Abstract

Abstract:

In regional power market, electricity generation and consumption resources from different provinces and cities compete on the same platform and are jointly cleared, enabling the free flow and optimal allocation of power resources. However, implementation faces two technical bottlenecks: joint clearing changes the existing distribution of interests among market participants, potentially reducing the interests and motivation of some participants, and the joint clearing and settlement process is complex, opaque, and difficult to supervise, making fairness hard to guarantee. To address these problems, this paper proposes a dividend redistribution mechanism for regional joint clearing and a joint clearing and settlement consensus algorithm which combines the proof of solution consensus mechanism with the traditional Byzantine fault tolerance consensus mechanism. The calculation results show that regional joint clearing can significantly reduce the total regional power supply cost and improve the efficiency of power resource allocation. Besides, the proposed dividend redistribution mechanism can achieve Pareto improvement, ensuring the willingness of market participants to engage in joint clearing. Furthermore, the proposed consensus algorithm enables market participants to reach consensus on clearing results and settlement schemes, ensuring the fairness, feasibility, and transparency of joint clearing.

Key words: regional electricity market, joint clearing, dividend redistribution, hybrid consensus algorithm
