The so-called "distributed energy resources" refers to the comprehensive utilization system of energy distributed on the user side. The primary energy is mainly gas fuel, supplemented by renewable energy, and all available resources are used; the secondary energy is mainly based on the co-generation of heat, electricity and cooling (value) distributed at the user end, supplemented by other central energy supply systems. Cascade utilization of energy to meet the various needs of users, and provide support and supplements through the central energy supply system; in terms of environmental protection, decentralize and recycle part of the pollution, and strive to achieve the goal of moderate emissions; focus on energy transmission and utilization The chip arrangement reduces the loss of long-distance energy transmission, and effectively improves the safety and flexibility of energy utilization.
