摘要：
By analyzing the existing frequency models of the systems with new energy, it is found that there exists a large margin of error under some certain conditions. By adding the limiting link of prime mover on the basis of the existing model, and distinguishing the proportion coefficient of effective adjustment and the proportion coefficient of effective inertia of the system, the frequency model and the simplified aggregation model of the new energy system with the limiting link are proposed. Typical system examples show that the two models have good fitting prediction effects under different new energy access proportions and different types. They can well reflect the overall inertia and the primary frequency regulation characteristics of the system. The actual power system example, which contains new energy and DC access, shows that the proposed simplified aggregation model can accurately reflect the frequency variation of the power system and has engineering application values. © 2021, Power System Technology Press.
