Power spot market is the core part of modern power market system
and it is the key step to improve market-oriented trading. All of the first eight pilot areas have been put into simulated trial operation
which marks a great step forward in the construction of power spot market in China. The similarities and differences in the construction scheme and related mechanism design of power spot market in the pilot areas are compared and analyzed from the three key aspects of construction framework
cohesion mechanism and operation mechanism. Some problems that the construction mechanism of electricity spot market is not compatible with the current electricity market system since the pilot area entered the simulation trial operation are analyzed
