Abstract

Control of power electronic generations is important in microgrids and power systems. Droop control is proposed for reasonable power allocation among different inverters. Moreover, virtual synchronous generator is proposed to improve frequency dynamics in transient state. Therefore, inertia design in VSG is necessary for integrating power electronic generations into grids. Frequency dynamic and stability are critical issues in traditional parameter design. However, power allocation for multiple virtual synchronous generations is usually ignored in transient state. This paper discuss inertia influence in paralleled virtual synchronous generators in microgrids. Transfer function model is constructed, where influence of inertia time constant is analyzed in terms of both frequency response and transient power allocation. Theoretical analysis and simulation results provide practical advice in inertia design for transient power allocation.
