Abstract: In order to summarize the trial operation experience of the first batch of pilot areas for power spot market construction, and promote the construction of power spot market in China, the market mechanism of Shandong power spot market is introduced, and the existing problems and some feasible solutions are studied based on an analysis of its trial operation situation. The operation features of Shandong power grid, such as the high penetration of clean energy, have dictated that the centralized power spot market mode may be more suitable for Shandong. Shandong power spot market consists of two timing markets, i.e., a day-ahead market and a real-time market, and an intra-day unit commitment, which is used as a cohesive mechanism. During the trial operation period, the overall operation of Shandong power grid is stable, and the power spot market clearing price changes with the relations between power market supply and demand. However, there are still some problems that need to be solved, including the market monitoring ability, the peak shifting compensation mechanism, and the prevention and control measures of users' trading risks. The research results show that the Shandong power spot market has basically met the conditions for continuous operation, but the improvement of market mechanism still needs to be continuously strengthened.
