n recent years, with the development of economy, people are paying more and more attention to environmental issues, and environmentally friendlynew energy sources are becoming more and more popular. Now, new energy power generation mainly wind power and solar energy-basedfoundation of the power generation system. However, due to the pulsation of the output voltage or current, there is a certain risk of grid connection, which may threaten the existing power system. Demand response can effectively solve the new energy grid instabilityproblems, eliminate bad risks, promote clean energy can ensure the safety of hair, to a certain extent on the grid systemdevelopment and use. Domestic smart grid technology is improving day by day, and distributed power generation is gradually being connected to the grid, which can basicallyprovide stable power to the terminal.
