Abstract

The operation of manufacturing plants (MPs) resultsin considerable energy consumption and carbonemissions. Existing studies typically adopt static carbonemission factors when estimating the carbon footprintsof MPs, overlooking their spatiotemporal variabilityacross different nodes of the power distribution network(DN). Thus, in this paper, we propose a two-layer energymanagement framework that explicitly accounts fordynamic carbon emission factors to achieve coordinatedlow-carbon operation between the DN and MPs. In theproposed framework, the upper-level model formulatesan electricity-carbon sharing problem among MPs,aiming to achieve cooperative utilization of renewableenergy and carbon allowances while minimizing the totaloperation cost. The lower-level model addresses theoptimal power flow of the DN, where the carbonemission flow (CEF) theory is employed to calculate thenode-level carbon emission factors. These factors arethen integrated with locational marginal prices (LMPs) toconstruct an electricity-carbon integrated pricingmechanism, which dynamically guides the upper-levelenergy scheduling and sharing decisions of MPs. Casestudies demonstrate that the proposed two-layer energymanagement framework can effectively reduce bothoperation costs and carbon emissions for MPs.
