维持系统频率质量是新型电力系统建设面临的关键挑战。高比例新能源电力系统的强源荷波动对自动发电控制(AGC)总体指令分配策略的合理性提出了更高要求。现有指令分配策略未考虑不同工况下调节电源对不同AGC指令的响应性能差异,AGC指令与电源运行工况之间的不适配易导致电源调频响应性能不达标。针对上述问题,提出动态匹配电源实时运行工况的AGC调节需求分解策略。首先,构建了基于数据驱动的电源调频性能达标感知模型,可在给定运行工况及接收的AGC指令下,感知电源调频性能能否满足考核要求,并基于此反推了给定运行工况下电源能够有效响应的指令范围;然后,针对当前常用的超前分配和实时分配,分别提出了内嵌电源指令适配范围的AGC分配策略,以提升AGC指令分配结果与电源运行状态的匹配度;最后,基于中国某省级电网实际燃气机组和水电机组数据验证了所提方法的有效性。
Maintaining the system frequency quality is a key challenge to the construction of new power systems. The strong source-load fluctuations in the power system with high proportion of renewable energy have brought a higher requirement for the rationality of the total command allocation strategy of the automatic generation control (AGC). Existing command allocation strategies do not consider the response performance differences of regulation sources to various AGC commands under various operating conditions. The mismatch between AGC commands and power source operating conditions is prone to causing the disqualification response performance. To address this issue
an AGC regulation demand decomposition strategy for dynamically matching the real-time operating conditions of power sources is proposed. First
a data-driven qualification perception model of power source regulation performance is established. Whether the regulation performance of the power source is able to meet the assessment standard can be perceived under given operating conditions and received AGC commands. Based on this
the command range that the power source can effectively respond to is reversely inferred under the given operating conditions. Then
for the commonly used advanced allocation and real-time allocation
the AGC allocation strategies embedded with the command matching range are proposed to improve the matching degree between the AGC command allocation results and the power source operating conditions. Finally
the effectiveness of the proposed method is validated based on the actual data of gas turbines and hydropower units in a provincial power grid in China.
