To fulfill targets in energy conservation and emission reductions, the Chinese government has made significant efforts to develop combined heat and power (CHP) plants, expand renewable power sources, and promote electric vehicles. These elements, however, are not always compatible with each other. Renewables—especially wind power—can be difficult to integrate into the energy system. This talk will discuss how to effectively integrate the three largest components of the energy system—power, transportation, and space heating—to better integrate renewables and lower emissions in China. For electric vehicles, the environmental impact of different electric vehicle types (public fleets and private light-duty vehicles) and charging strategies (fast or slow charging) will be analyzed based on hourly simulations that consider driving behavior and power system operations. For integrating electric power and heating systems, reconciling the conflict between intermittent wind power and inflexible CHP plants through introduction of more flexible heating technologies (heat pumps, heat storage, and electrical boilers) will be analyzed by a proposed energy system optimization model.
