摘　　要：为实现先进绝热压缩空气储能(AA-CAES)系统在宽负荷段参与AGC调频,且调节速率不超过《广东调频辅助服务市场交易规则》规定(避免产生考核电量),提出一种多级分段设置PID控制器参数参与机组自动发电控制(AGC)调频的控制策略。通过APROS仿真平台分别对10 MW AA-CAES机组采用单套与3套PID控制器响应AGC控制指令进行仿真。结果表明:AA-CAES发电系统机组采用1套PID控制器在宽负荷段响应AGC控制指令,调频性能指标K1大于5,给储能电站增加考核电量而造成经济损失;机组采用3套不同参数PID控制器能够优化调频性能指标,使调频性能指标K1在要求范围内,从而避免产生考核电量,有效提高AA-CAES发电系统参与辅助调频服务的经济效益。In order to realize the advanced adiabatic compressed air energy storage(AA-CAES) system participates in AGC frequency regulation in wide load range, and ensure the regulation rate does not exceed the Guangdong Frequency Regulation Auxiliary Service Market Transaction Rules(to avoid generating checking energy), a control strategy with multi-level segmented parameter setting PID controller participating in the frequency regulation of unit automatic generation control(AGC) is proposed. Through APROS simulation platform, the response of 10 MW AA-CAES unit to AGC control instructions is simulated by using a single set of PID controllers and three sets of PID controllers. The research results show that, when the AA-CAES power generation system unit adopts one set of PID controller to respond to the AGC control instructions in wide load section range, the frequency modulation performance index K1 is greater than 5, which increases the assessment power of the energy storage power station and causes economic losses. When the unit adopts three sets of PID controllers with different parameters to optimize the frequency modulation performance index, the frequency modulation performance index K1 is within the required range, thereby the possibility of generating electricity for assessment is avoided and the economic benefits of the AA-CAES power generation system participating in auxiliary frequency modulation service is effectively improved.
