摘要

针对先进压缩空气储能（advanced adiabatic compressed air energy storage, AA-CAES）系统释能发电阶段储热或储气能量不足时,膨胀发电机组将被迫突发停机,负荷突降会对电网稳定性造成冲击的问题,提出AA-CAES系统释能发电阶段安全减出力控制的控制策略,同时基于10 MW AA-CAES系统建立安全减出力控制仿真回路,探讨降负荷速率、蓄热罐水位限定值等关键参数对AA-CAES系统发电过程的影响。仿真结果表明,投入安全减出力控制回路能够有效延长AA-CAES系统释能发电时间,为电网提供应急安全时间,能有效缓解突减负荷对电网的冲击,具有广阔的推广应用空间。

Abstract

In energy release stage, advanced adiabatic compressed air energy storage （AA-CAES） system will be forced to shut down suddenly when heat storage energy or gas storage energy is insufficient, and load shedding will impact the stability of power systems. In view of the above problem, this paper proposes a control strategy of runback （RB） in the energy release stage of AA-CAES systems, and establishes relevant control simulation circuit adapting to a 10 MW AA-CAES system. Moreover, the influence of load shedding rate and the limit values of hot tank liquid level on the power generation process of AA-CAES systems is discussed in this paper. The simulation results show that the control strategy of runback can prolong the effective power generation time of AA-CAES system, and a long safety emergency duration for power systems is provided which effectively alleviates the impact of sudden load reduction on power grid and has broad application prospect.
