Capacity Planning of Park Integrated Energy System Considering Ladder-Type Carbon Trading

Abstract

To comprehensively address the low-carbon and economic aspects of the park integrated energy system (PIES) within the context of "dual carbon" initiative, this paper presents a multi-stage capacity planning approach for the PIES, which incorporates the step carbon trading mechanism. A carbon trading cost calculation model is developed considering the stepped carbon trading mechanism. Additionally, a multi-stage planning model is formulated for the PIES with the objective of minimizing the total costs, including investment, operation, maintenance and carbon trading expenses throughout the planning period. Further simulations are conducted to explore the reasons for the negative carbon trading cost observed in the PIES, as well as to examine the sensitivity of the multi-stage planning model to the carbon trading benchmark price and the length of the carbon trading price interval.
