| 摘要: |
| 随着风光新能源接入电网的比例不断增加，大型风电场和光伏电站也开始参与区域电网二次调频。为此，搭建了考虑风光新能源参与二次调频的多源最优协同控制模型，以解决区域电网二次调频的实时总功率在不同类型调频电源上的动态分配问题。为解决这个复杂非线性优化问题，采用简单模式搜索算法进行求解，以快速获得不同功率扰动情况下的高质量功率分配方案，从而提高整个区域电网的动态响应调节性能。最后，利用扩展的IEEE标准两区域模型对所搭建模型进行验证，并通过对比传统工程分配方法及智能优化算法来测试应用算法的性能。 |

| Abstract: |
| As the amount of wind and solar renewable energy connected to the power grid gradually increases, large-scale wind farms and photovoltaic (PV) stations begin to participate in secondary frequency control for an interconnected power grid. In this situation, an optimal coordinated control of multi-source for secondary frequency control with wind and solar renewable energy is constructed, which can distribute the real-time total power to various regulation resources. To handle this complex nonlinear optimization, a simple pattern search is used to rapidly obtain a high-quality dispatch scheme under different power disturbances. Thus the dynamic response regulation performance of the control area can be improved. Lastly, an extended IEEE two-area control model is designed to evaluate the performance of the proposed technique and it is compared with the engineering dispatch method and intelligent optimization algorithms.
