The Study of Spot Electricity Trading In View of Big Dispatching Mode and Market Monitoring Measurements

Nowadays, China's electricity spot trading pilot work has been gradually launched, and the Chinese traditional scheduling model will be broken. The dispatching department should grasp the operation method of large power spot trading market integration and real-time power grid operation mode. In this paper, the big dispatching mode concept is proposed and should be accepted as the starting point in the generation side and retail side to maintain system security and stability of the market. Based on the analysis of the advantages and disadvantages of the 5-30 minute clearing spot trading scheme in foreign mature electricity markets, this paper discusses the uniqueness of spot trading in China's 15 minute cycle. According to the time difference between dispatching center's online calculation and 15 minute trading cycle, a closed loop control method is put forward, which uses online artificial intelligence technology to do spot price forecasting, power grid security check and transaction mode design. It is suggested that the electricity trading center should announce the spot price forecast results to the market members in time, and encourage the members of the market to adjust the operation mode according to the price signal. Also, in the power generation side, according to the impact of electricity generation share in foreign power market on the spot market, this paper puts forward the share management method of regional power generation group adapting to China. At the same time, it advocates to supervise the market through encouraging and compatible financial means, and carries out the capital audit and credit evaluation to the market participants according to the share size, so as to serve the safety, low carbon and stable electricity market of our country.
