| 摘要: |
| 随着可再生能源渗透率的逐步提高，电力系统惯性水平下降，系统频率安全稳定面临挑战，迫切需要配置需求侧快速响应资源参与系统频率调节服务。针对此问题，分析了变频空调、储能和电动汽车提供电力系统调频备用的可行性，建立考虑上述需求侧快速响应资源的频率安全约束联合经济调度模型，以进行源荷双侧调频备用的统一优化。然后，引入基于高维模型表达的数据驱动方法将调频备用与最大频率偏移量之间的高阶非线性、隐式关系转换为低阶、显式表达式，从而实现频率安全约束经济调度模型的简化和求解。最后，结合IEEE 30节点系统验证了所提调度模型和方法的有效性，以及所提的数据驱动频率安全约束可确保系统在不平衡功率下的异常频率在约束范围内，且需求侧快速响应资源对于提升系统频率韧性具有重要正向作用。 |

| Abstract: |
| he frequency of the power system faces challenges with the growing share of renewable energy and the decreasing inertia. It’s urgent to allocate fast demand response resources for frequency regulation. In this paper, the feasibility that inverter air conditions, energy storage and electric vehicles provide frequency regulation reserve is analyzed. A frequency constrained combined economic dispatching model (FCCED) considering the above fast demand response resources is established to uniformly allocate the frequency regulation reserve between generators and loads. Then, a data-driven method based on the high dimensional model representation (HDMR) is proposed to convert the above high-order, nonlinear and implicit frequency security constraint to a low-order and explicit constraint. As a result, the proposed FCCED model can be solved easily. Finally, the modified IEEE 30-bus system validates the effectiveness of the proposed method. It is explained that the proposed frequency security constraint ensures that the abnormal frequency of the system under unbalanced power is within the constraint. And fast demand response resources have an important positive effect on improving the frequency toughness of the system.
