In the process of distribution network planning,considering the demand side management can increase the acceptance of distributed generation(DG)and improve the system economy.Aiming at the problem that demand side management does not consider the impact of carbon emissions in the planning model,a distribution network expansion planning method considering low-carbon emissions and demand side management is proposed.Firstly,a carbon trading cost measurement model for the distribution network is established based on the dynamic carbon emission intensity derived from the carbon emission flow theory.Subsequently,a low-carbon demand-side management strategy is proposed.Thereafter,a bilevel optimization model for distribution network planning and operation,considering carbon trading and demand-side management,is developed.In the planning layer,the objective is to minimize the annual comprehensive cost by determining the optimal configuration of lines,DG,and energy storage.In the operation layer, the goal is to minimize the system's operational costs by formulating the optimal operational strategy for the distribution network under typical daily scenarios.Finally,simulation and calculation based on the modified IEEE 33-bus distribution network demonstrate that the expansion planning scheme for the distribution network,which considers low- carbon demand-side management,reduces economic costs by 2.0%and carbon emissions by 8.8%.This validates the effectiveness and superiority of the proposed method.
