Abstract
Distributed inverter-based power sources have become the main components of microgrids (MGs), and the virtual synchronous generator (VSG) concept is considered useful for improving the robustness of MGs. However, various problems such as the burden of unbalanced loads, parallel operation of multiple inverters, and harmonics of the system voltage received from household electric loads can arise when constructing an MG in an emergency using a domestic single-phase three-wire (1P3W) system. Therefore, we introduce a new VSG method for 1P3W systems to address these issues. This method is based on the previously proposed VSG methods for three-phase and single-phase two-wire systems. In this paper, we demonstrate that a small-capacity inverter with two VSGs can stably supply electrical power to 1P3W home appliances.
