考虑氢燃料电池响应延迟特性的电网日内优化调度

在以往调度模型中忽略了氢储能系统中氢-电环节氢燃料电池（HFC）作为一种电源其自身的响应延迟特性,这将造成电网切负荷并影响其稳定运行;由于HFC在不同负载其最优运行温度不同,当HFC在常温下启动时,工作温度的变化是造成其响应延迟的主要因素,因此该文从HFC的工作温度出发,分析HFC的响应延迟特性,建立其响应延迟特性模型,并分析负荷对其响应时间的影响,得到其在不同载荷率下的响应时间,最后结合电网日内调度周期的特点,提出根据HFC的载荷率不同,制定其能够响应不同调度周期的日内调度策略。

INTRADAY OPTIMAL DISPATCH OF POWER GRID CONSIDERING RESPONSE DELAY CHARACTERISTICS OF HYDROGEN FULE CELLS

In the previous dispatch model, the response delay characteristics of the hydrogen-electric link hydrogen fuel cell （HFC） as a power source in the hydrogen energy storage system were ignored, which would cause load shedding of the power grid and affect its stable operation. The optimal operating temperature of HFC is different under different loads. When HFC starts at room temperature, the change of operating temperature is the main factor that causes its response delay. Therefore, aiming at the working temperature of HFC, this paper analyzes the response delay characteristics of HFC, establishes its response delay characteristic model, and analyzes the influence of load on its response time, and obtains its response time under different load rates. Finally, combined with the characteristics of the intraday dispatch period of the power grid, the intraday dispatch strategies that is formulated can respond to different dispatch periods according to the different load rates of the HFC.
