In order to meet the needs of energy transformation and power grid development, diversified and high elastic power grid is being constructed in Zhejiang province. Demand response is the core carrier to realize the source-load interaction, which can alleviate the tight balance between regional power supply and demand, and support the grid elasticity with strong interaction ability. Based on the development needs of Zhejiang high elastic power grid and the practical course of demand response, the working experience of Zhejiang demand response is summarized. The development direction of deepening demand response business in the background of energy Internet is also put forward, in order to provide reference for the research and application of demand response in China.
