Transient Angle Stability of Paralleled Synchronous and Virtual Synchronous Generators in Islanded Microgrids

Project Code :TEMAPS232

Objective

The main objective of this project is reduce swing equations, improve the transient stability of the paralleled SG-VSG system by changing the equivalent input torque of the system.

Abstract

In this project, Virtual Synchronous Generator (VSG) techniques, parallel operations of Synchronous Generators (SGs) and VSGs is proposed. The differences between paralleled systems will affect transient stability of the system, which probably threatens stable operation of the system, especially under fault conditions. 

In this paper, transient angle stability of a paralleled Synchronous and Virtual Synchronous Generators (SG-VSG) system is investigated by compared with that of paralleled VSGs system. It is observed that the paralleled SG-VSG system is more prone to transient instability due to the differences between their speed governors. Then, a control method is proposed to improve the transient stability of paralleled SG-VSG system. Furthermore, a Lyapunov method is employed to establish the nonlinear model of islanded microgrid, by which the attraction domain of paralleled system is quantified.

Keywords: Virtual Synchronous Generator, Microgrids, Lyapunov function, Transient Angle Stability.
