摘要

Abstract

Reducing carbon emissions in the power sector is critical for transitioning to a sustainable and low-carbon future. Estimating carbon efficiency of demand side response (DSR) in the power system is an important step towards realizing potential environmental benefits. Marginal emission factor (MEF) is an effective tool for estimating incremental changes in carbon emissions as a result of a change in demand. However

estimation methods currently used for evaluating MEF can be improved upon

specifically

by factoring in the ramp-rate constraint of generators in the fuel cost based merit order dispatch. In this paper is described a new method for MEF assessment under ramp-rate constraints; the method is then compared with two conventional estimations in a British power system. Three fuel price scenarios are used to conduct a sensitivity analysis of MEFs to fuel prices. Conclusions are drawn that can pave the way for future improvements in estimating MEF in power systems.
