N2 - This paper presents a control scheme for enforcing coherency in a power electronics dominated grid (PEDG) comprising multiple grid-forming (GFM) and grid-following inverters (GFL) based distributed generation (DG). Based on different applications and grid requirements, the primary control for DG can vary such as GFM, GFL, etc. Moreover, each DG can have unique parameters such as controller gains, power ratings, and filter model parameters. All these factors intrinsically contribute towards the heterogeneity in the PEDG. Furthermore, DGs are increasing steeply to integrate renewable energy generation. Therefore, performing different analysis on such a large network is becoming a big challenge recently. One of the solutions is performing aggregation based on similar behaving DGs that can significantly decrease the computational burden and analysis time. Thus, this paper proposes coherency enforced (CE) control to acquire coherent and homogeneous dynamic characteristics for inherently heterogenous cluster of GFM and GFL inverters based DGs. Various case studies are presented to validate the effectiveness of the proposed approach.
