文摘随着不确定性可再生能源大规模并网,电网频率特性日益复杂。传统火电机组具有响应时间长、无法准确跟踪指令等问题,亟须利用储能提高火电机组参与自动发电控制(automatic generation control,AGC)调频时的调节性能。首先,针对调频考核规则,建立调频性能指标数学模型,并考虑火储系统出力特性,结合改进层次分析法校正调频子指标权重系数,以此构建以调频性能最优为目标的第一阶段优化模型;在此基础上,为了减少储能荷电状态(state of charge,SOC)越限和深度充放情况,以储能SOC偏差最小为目标构建第二阶段优化模型。仿真验证表明:所提的两阶段调频方法能够提高火储联合系统的调频性能和调频收益,同时有效减少储能深度充放情况和工作寿命损耗,提高储能辅助调频服务的可持续性。
