At present, China's power supply structure and energy consumption pattern have undergone new challenges, and a new power system with renewable energy as the main supply is being constructed. However, the time block division in some regions has not been able to meet the developing requirements of the new condition. In addition, the current peak-valley difference still has room to expand. Small price difference may lead to the weakening of load regulation. Therefore, by constructing various electricity pricing mechanisms and analyzing users' satisfaction degree and load transfer level, this paper optimizes the current electricity price system, encouraging users to use electricity reasonably and promoting the development of renewable energy.
