VOC-Based GFM Inverter Control Strategy for Distribution System Blackstart with Emphasis on Self-Synchronization

Abstract

The Japanese government aims to achieve carbon neutrality by 2050 and transition to renewable energy sources.

However, traditional methods for restoring the power system after blackouts may not be suitable for future renewable energy-based systems. This study proposes a novel system restoration method based on inverter based power resources in an islanded distributed microgrid. The study focuses on the self-synchronization of inverter based power resources and employs a simulation approach using the VOC (Virtual Oscillator Control) based grid-forming inverter. Results show that the proposed method can provide an effective and efficient approach for system restoration in distributed microgrids. This activity highlights the potential of the proposed method in enabling a smooth transition towards a renewable energy-based power system.
