The paper presents a distributed secondary control strategy for voltage regulation and reactive power sharing in microgrids with grid-forming (GFM) inverter-based resources (IBRs). The proposed scheme is based on a distributed optimization framework, allowing each GFM IBR to utilize decentralized measurements and neighborhood information in the communication network for the control updates.
The key highlights of the approach are:
A fully distributed synthesis and plug-and-play operation of the secondary controller, enabling individual GFM IBRs to choose control objectives based on their local requirements without centralized constraints.
Convergence analysis establishing voltage regulation and reactive power sharing properties of the proposed scheme.
Versatility in achieving diverse trade-offs, where some GFM IBRs can emphasize voltage regulation while others focus on reactive power sharing.
Privacy-preserving updates, where only non-linear estimates are shared between GFM IBRs during the control updates, safeguarding private information.
The performance of the proposed distributed secondary control scheme is evaluated using a controller hardware-in-the-loop (CHIL) experiment, demonstrating its efficacy in achieving reactive power sharing and voltage regulation objectives.
