Coordinated optimization model of urban multi-energy supply and ecological environment restoration based on “novel energy cell”

A coordinated optimization model of urban multi-energy supply and ecological environment restoration based on “novel energy cell” cluster is proposed in the paper for dealing the rapid growth of the proportion of renewable energy and the increasing requirements of compatibility and coordination between urban ecological environment governance facilities and multi-energy systems, which contain electricity, heat, cold, and gas. First, the concept of novel energy cell and its mechanism model, which has ecological restoration functions such as sewage and waste treatment, is proposed in the paper. Second, the interaction mechanism between multi-energy supply benefits and ecological restoration benefits in the novel energy cell cluster is studied, and the quantification model of the comprehensive benefits of the novel energy cell cluster is established. Then, with the objectives of the maximum energy saving rate, the maximum emission reduction of system pollutants, and the minimum total operating costs of the system, a comprehensive benefit optimization model of urban multi-energy system and its solving algorithm are established. Finally, a simulation model is established. The simulation results show that the proposed method is conducive to the coordinated development of the integration of energy, environment, and economy of the city.
