This paper introduces a novel Distributed Robust Volt-VAr Control Strategy (DRVVCS) aimed at achieving accurate proportional reactive power sharing in islanded microgrids, emphasizing adaptability, simplicity, and reduced reliance on communication. This scheme also enhances the flexibility and scalability of the system, which are generally challenging in distributed control schemes. The system’s seamless transition between different network topologies and accurate reactive power sharing under varying loads with suggested DRVVCS are evaluated through comprehensive simulations. The proposed scheme is also tested on a standard IEEE 33-bus system with three sources and a standard IEEE 69-bus system with three and five sources to observe its effectiveness in different operating scenarios. The proposed DRVVCS is compared with conventional droop control and other existing methods to showcase its effectiveness and versatility.
