Abstract:

Take the distributed energy station reconstruction project in Shanghai as an example, the distributed energy system pollutant emission varying trend was studied. Based on the distributed energy system environmental benefits evaluation model, the environmental benefits and cost of distributed energy system and traditional coalfired power was analyzed. The study result indicated that, compared with traditional power plant, the environmental index of distributed energy system is significantly higher. Environmental cost of distributed energy system is only onethirteenth of traditional coalfired power plant. Quantitatively analyzing distributed energy system is not only providing environmental data for control system improvement, but also providing data for the development of distributed energy system.
