Abstract

Abstract:

In the context of carbon peaking and carbon neutrality goals, power consumers are increasingly paying attention to the environmental attributes associated with traded energy in power transactions. Therefore, the development of a trading-based method for allocating carbon responsibility to power consumers is imperative. This paper fully considers the trading characteristics across the entire process of electric energy trading, proposes a new carbon emission flow model and new solution method for spot trading, designs a connection mechanism for the carbon emission flow of each process of electric energy trading, and establishes a carbon allocation method throughout the entire process of electric energy trading considering spot trading. Finally, this paper conducted numerical analysis using the PJM 5-bus system, IEEE 39-bus system and IEEE 118-bus system. The results demonstrate that the proposed method can stably and reasonably achieve the allocation of spot trading carbon responsibility, assist market participants in managing carbon responsibility risks, efficiently model the impact of the entire process of electric energy trading on carbon allocation, and demonstrate efficient computational performance.

Key words: carbon emission flow, electricity market, carbon measurement, carbon market
