Combined with the trial operation of electricity spot market in South China (starting from Guangdong province) in 2021, this paper carries out simulation research on the spot electricity energy market in Guangdong with demand response. Firstly, it summarizes and analyzes different types of demand responsere source, the participation modes and the organizational process of Guangdong spot market incorporating demand response resource. Secondly, the time-sharing output characteristics and bidding characteristics of demand response resources are analyzed. A day-ahead clearing model and a settlement model taking into account the demand response are established. Then, based on the electricity market simulation system designed by the research institute of China Southern power grid, the boundary conditions such as unit bidding information, demand response bidding information and supply and demand curve under the spot market environment of Guangdong are simulated. Finally, the paper simulated the clearing results of Guangdong day-ahead spot market, analyzed the impact of demand response on spot price, unit power generation cost and user electricity charges, and studied the benefits of demand response participating in the spot market under different settlement modes.
