Abstract

With accelerating climate change and policy-driven mandates for carbon neutrality, cities are prioritizing low-carbon transitions in energy systems. In response to this urgent need, this paper proposes a low-carbon-oriented planning framework for urban multi-operator integrated energy system (UMIES), integrating multi-operator coordination, carbon emission cost and system feasibility. Firstly, a novel low-carbon/economic feasible region model is developed to harmonize multi-operator resource allocation with carbon reduction goals, and the low-carbon-oriented optimal allocation model is further developed. Then, the coordinated planning approach based on feasible region projection is proposed, which enables the multi-operator optimal allocation realized in a privacy-protected, iteration-free and calculation-distributed fashion. Case studies validate the method’s efficacy in balancing economic viability, carbon mitigation, and privacy protection, offering a practical pathway for sustainable urban energy planning.
