Low-carbon Economic Dispatch of Industrial Community Considering the Demand Response of Energy-Extensive Industrial Loads

Energy-extensive industrial users have high emission attributes and also have considerable demand response potential. This paper presents a low-carbon economic dispatch of industrial community considering the demand response of energy-extensive industrial loads. Based on their operational characteristics, the energy-extensive industrial loads are developed for demand response. While the steel load is divided into continuous and intermittent load, the cement load is divided according to its raw material and clinker. Considering the aluminum smelting from electrolysis process, the electrolytic cell is the main power consumption determined by electrolysis temperature and current. Based on the spatial-temporal distribution characteristics of air pollutants and the environmental policy, the environmental protection costs of thermal power units and energy-extensive industrial loads are calculated to formulate a low-carbon economic objective function. Case studies on an industrial community is carried out to show its effectiveness and superiority on cost and carbon emission reductions.
