在光伏装机容量占比不断提高、电力系统低惯量问题日益凸显的当下，如何评估光伏并网系统惯量支撑能力、通过调频参数的整定使系统频率满足并网导则的需求是亟待解决的关键问题。为此，通过类比同步发电机的转子运动方程，对已配备典型附加调频控制的光伏并网系统等效惯量做了量化评估；然后，考虑光伏设备的物理约束及新能源并网导则的需求，给出了集中式光伏并网系统调频控制参数的整定方法；更进一步，在前述物理约束和并网导则需求的基础上，额外引入网络线路损耗最低的目标，给出了分布式光伏并网系统的调频控制参数整定方法；最后，利用MATLAB/Simulink仿真验证了调频控制参数整定的正确性。

As the proportion of photovoltaic installed capacity continues to increase and the low inertia problem inpower systems becomes increasingly prominent, how to evaluate the inertia supporting capacity of a photovoltaic grid-connected system and how to set the frequency modulation parameters of the system to meet the requirements of grid-connected guidelines are the key issues to be solved urgently. The equivalent inertia of a typical grid-connected photovoltaic system with additional frequency modulation control is quantitatively evaluated by analogizing the rotor motion equation of synchronous generators. Then, considering the physical constraints of photovoltaic equipment and the requirement of new energy grid-connected guidelines, the frequency modulation control parameter setting method for a centralized photovoltaic grid-connected system is put forward. Furthermore, based on the physical constraints and grid-connected guideline requirements, a target of minimum network line loss is introduced additionally, and the frequency modulation control parameter setting method for a distributed photovoltaic grid-connected system is formulated. Finally, the simulation results based on MATLAB/Simulink verify the correctness of frequency modulation control parameter setting.
