| 摘要: |
| 当前新能源电站有功功率控制主要采用通信指令调节大量逆变器和风机等设备的方式，其有功功率控制速度慢，无法满足系统级有功功率紧急控制对新能源场站级有功功率控制提出的要求。为此，结合当前新能源电站有功功率控制模式，利用保护装置毫秒级开断速度的优势，提出一种有功功率柔性控制方法，并设计该控制方法的系统架构及有功功率控制流程，以满足正常运行时自动发电控制和紧急情况时快速控制的双重需求。提出多目标约束有功功率优化控制的数学模型，并阐述通过改进的优先顺序法求解该数学模型的具体步骤。通过现场实际应用的案例分析，验证了所提方法的可行性和有效性。 |

| Abstract: |
| Currently the active power control of renewable energy station mainly employs the communication command to adjust a large number of inverters and wind generators. However, the active power control speed is slow, which cannot satisfy the requirement of active power emergency control at the system level. A flexible active power control method based on current active power control mode of renewable energy station is proposed, in which the advantage of millisecond breaking rate for the protection device is fully exploited. The system architecture of the proposed method and active power control process is designed. A mathematical model with multi-objective constrained active power optimization control is proposed, which is solved by an improved priority list method. The feasibility and effectiveness of the proposed method are verified by practical engineering application case study. |
