摘要

波动性风电的高渗透接入降低了系统的阻尼和一次调频性能，制约了风电渗透率的进一步提升。研究在不降低系统动态稳定水平的前提下提高高风电渗透率系统的调频能力，对于提高风电渗透率极限具有重要意义。文中首先提出了一种含阻尼水平约束和频率偏差约束的风电渗透率极限求解方法，进一步基于火电机组惯性参数对系统阻尼特性和一次调频性能有相反作用的机理，提出了一种考虑系统阻尼和动态频率响应能力的火电机组惯性参数协调优化方法。仿真结果表明，所提风电渗透率极限求解方法的计算结果有较高的参考价值，引入协调优化策略后有效改善了系统的动态稳定特性和调频特性，优化效果适用性强，优化后系统风电渗透率得到了提高。

Abstract

The high-penetration integration of volatile wind power degrades the damping characteristic and the primary frequency regulation performance of the power system

which restricts the further improvement of the wind power penetration. This study improves the frequency regulation capability of the high-penetration wind power system while maintaining the dynamic stability level of the system

which is of great importance to increase the wind power penetration limit. Firstly

the paper puts forward a solution to the wind power penetration limit with constraints of damping ratio and frequency deviation. Then

based on the opposite effects of inertial parameters of thermal power units on the damping characteristic and the primary frequency regulation performance of the system

a coordinated optimization method for the inertial parameters of thermal power units is proposed

which considers the damping ratio and dynamic frequency response capability of the system. The simulation results prove that the calculation results of the proposed solution to the wind power penetration limit are of high reference value. After the introduction of the coordinated optimization strategy

the dynamic stability characteristic and the primary frequency regulation characteristic of the system are improved effectively. The optimization effect has a strong applicability and the wind power penetration of the power system has also been improved.
