Abstract: The existing evaluation method for demand-side management energy-saving cannot quantify the energy-saving produced by the change of the energy types of the terminal equipment, and the traditional electric power replacement evaluation method cannot take into account the influence of the real power source structure based on the power network flow. An energy-saving and emission-reduction evaluation model is established, which takes into account the power network, power source structure and electricity use mode. The energy consumption coefficient of electricity (ECCE) and coal consumption coefficient of electricity (CCCE), which characterize the energy consumption level of the power system, are proposed and deduced. The energy saving and emission reductions of electric power replacement project are quantified from the perspective of whole process based on generalized energy saving. The spatiotemporal characteristics of ECCE and CCCE are studied through case study, and a typical scenario database is established. Through demonstration of electric vehicle (EV), the operation of electric power replacement project optimized through demand response and energy storage has positive impact on evaluation index.

Key words: power source structure, generalized energy saving, energy consumption coefficient, spatiotemporal characteristics
