Abstract

Abstract:

The real-time storage power of automotive electric thermal phase-change energy storage system exceeds the preset power value, which will cause excessive transformation of power resources and lead to energy waste. This paper designs a dynamic optimization method for heat storage performance of new energy low-carbon vehicle electric thermal phase change energy storage system. The feasibility of low-carbon mechanism of new energy was analyzed, the objective coordination function of electric heating energy storage was constructed, the active power threshold of phase change energy storage system was set, the power conversion relationship between transformer and electric heater group was combined, the constraint conditions of dynamic heat storage were solved, and the dynamic heat storage performance of automotive electric heating phase change energy storage system was analyzed. Experiments show that the method can avoid the situation that the real-time storage power exceeds the preset power value.

Key words: new energy low-carbon, electrothermal phase transformation, energy storage system, dynamic heat storage
