This paper examines the influence of grid forming control on power system oscillations in in systems incorporating renewable energy sources. One of the grid forming control approaches is considered in detail: virtual synchronous generator (VSG) control, which have proven its effectiveness in large power systems. VSG with detailed control blocks is employed for analyzing their influence on the power system oscillations. The 4-machine 2-area system is utilized as a platform for implementing the VSG. Modal analysis is performed for evaluating the contribution of different states on the power system oscillations. Additionally, time domain simulation results are presented for validating the findings of the modal analysis.
