Abstract

Abstract:

With the rapid development of new energy,the electric permeability of power system increases gradually,and the system presents the characteristics of low inertia.Virtual inertia control is one of the main ways to improve the frequency support ability of low inertia systems,but it will change the equivalent inertia level of the system and affect the frequency adjustment process.In order to solve these problems,the distributed frequency control strategy considering the influence of inertia is proposed.The power instruction compensation prediction output model of the virtual inertia controller is introduced.The distributed model prediction frequency controller based on the model is designed.The simulation results show that the proposed control strategy can effectively improve the frequency control performance and restrain the excessive adjustment of wind turbines in frequency control to a certain extent.

Key words: frequency control, model prediction control, virtual inertia control, low inertia power system
