Dispatch for Urban Integrated Heat and Power System Considering Secondary PM2.5 Under Smart Environmental Sensing

To improve the air quality and reduce the human settlement pollution, the effects of initial air pollutant emissions from urban heat and power generation with the diffusion of pollutants were often considered in the energy system dispatch, but the effects of secondary PM2.5 hazards caused by the urban energy system were almost ignored. In the urban integrated heat and power systems (UIHPS), under the support of smart environmental sensing, the introduction of integrated demand response (IDR) between the energy production side and consumer side is an effective means of reducing primary and secondary PM2.5 hazards. As for the diffusion of primary pollutants and the generation of secondary PM2.5 are affected by the uncertainty of weather conditions, a stochastic environmental economic dispatch (SEED) model for UIHPS considering IDR is proposed in this paper. Linearized secondary PM2.5 generation and diffusion functions for UIHPS dispatch are introduced into the objective function. The price-based IDR is performed on the Stackelberg game mechanism, and the game equilibrium solution is transformed as the SEED’s constraint set by using the backward induction method. Simulations show that under the partly data supply from smart environmental sensing, the SEED model considering the secondary PM2.5 and IDR can effectively alleviate the comprehensive hazard of PM2.5 under severe haze weather.
