摘要：

汽车电热相变储能系统实时储热功率超过预设功率值，会造成电力资源过度转化，导致能源浪费。对此设计新能源低碳汽车电热相变储能系统储热性能动态优化方法。分析新能源低碳机制的可行性，构建电热储能的目标协调函数，设定相变储能系统有功功率阈值，配合变压器与电加热器组之间的功率转换关系，求解动态储热约束条件，完成对汽车电热相变储能系统的动态储热性能的分析。实验证明，上述方法可以避免出现实时储热功率超过预设功率值的情况。

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
