Source‐storage‐transmission planning method considering carbon emission responsibility allocation

Abstract Fair sharing of carbon responsibility is crucial to achieve the goal of low‐carbon transformation and dual‐carbon power system. In response to the current issue of a certain proportion of joint responsibility between source and load, it does not comply with the principle of “who causes who bears”. This thesis proposes a source storage transport coordinated planning method for allocating carbon responsibility from a planning perspective. Firstly, based on the basic principle of “who causes, who bears”, it classifies and holds accountable various stakeholders, establishes reasonable and fair allocation principles including reward and punishment indicators, and a dual carbon responsibility cost allocation rule for electricity balance and power balance in the power system; Secondly, based on the previous works, a source storage network joint planning model which comprehensively considers the investment cost of conventional thermal power installation, energy storage investment, wind abandonment penalty cost, transmission line expansion cost, and carbon emission responsibility cost is constructed. Finally, taking the Garver‐6 node system as an example, the effectiveness and feasibility of the proposed method were verified by comparing it with the source storage and transportation planning method that does not consider carbon responsibility allocation.
