| 摘要: |
| 为了解决传统自动发电控制(AGC)“先有偏差再调节”带来的发电机损耗、系统频率质量降低等问题，综合考虑传统AGC机组、储能、可调节负荷的频率调节性能，设计考虑新能源分钟级功率波动性的源网荷储协同频率控制策略。基于分钟级风光发电可用功率和负荷可调节能力，以未来15 min的调度时段内每分钟系统可调节资源的调节量为决策变量，以调频成本最低为目标，考虑系统运行约束、可调节资源调节特性约束、性能指标约束，构建源网荷储协同频率控制优化模型。算例分析结果表明，所提方法减少了传统调频机组的调节次数及单次调节量，实现了高渗透率风光发电接入电力系统的灵活高效调频。 |

| Abstract: |
| In order to solve the problems of generator loss and system frequency quality degradation caused by the “deviation first and then adjustment” of the traditional automatic generation control(AGC),comprehensively considering the frequency regulation performance of traditional AGC units, energy storage and adjustable load, a source-grid-load-energy storage cooperative frequency control strategy considering minute-level power fluctuation of new energy is designed. Based on the minute-level available power of wind and photovoltaic power generation and adjustable capacity of load, the adjustment amount of system adjustable resources per minute in the next 15 min scheduling period are taken as the decision variables, the source-grid-load-energy storage cooperative frequency control optimization model is constructed with the lowest frequency modulation cost as the objective, which considers the system operation constraint, the regulating characteristic constraint of adjustable resources and the performance indicator constraint. The results of example analysis show that the proposed method reduces the regulation times and single regulation amount of the traditional frequency modulation units and realizes the flexible and efficient frequency modulation of the power system with the integration of high permeability wind and photovoltaic power generation. |
