Small signal modelling and Parameter Analysis of Virtual Synchronous Generator Based Control in Isolated Microgrid

Abstract

The virtual synchronous generator control is introduced to the power electronic interfaced inverters to control voltage and frequency in the islanded microgrid. In order to establish safe operating conditions for islanded microgrid various values of moment of inertia, damping constant, Q-V droop constant values are taken in this paper to justify the system behavior. Validation of the MATLAB/simulation model is done through the small signal modelling of the electrical system and is verified by the eigen value plot of the system to check the feasibility and correctness of the system. The dynamic performances of the model in terms of current, voltage, active power, reactive power and frequency is analysed.
