Discussion on the technical architecture of smart grid in Hainan

Smart grid demonstration projects are being carried out all over the world, but none of them involves integrated demonstration of large island-based power grid. This paper analyzes the demand for smart grid in Hainan, proposes a 4-layer technical architecture including generation, transmission, distribution, and consumption. On this basis, the core business of the overall technical architecture is discussed, which include intermittent energy consumption and smart disaster early warning. Then the structure and functions of the support system are introduced. Finally, the key technologies and development trends are discussed.
