Abstract

To enhance the stability and resiliency in autonomous microgrids, distributed frequency and voltage restoration controllers are prominently used. These controllers are executed using consensus algorithm which allows them to work
in a cooperative manner by exchanging information among their neighbors. This information exchange is achieved through a cyber network which inherently exhibits time delays, packet loss, etc. However, traditional approaches in simulation do not translate an accurate model to incorporate the abovementioned variables in a cyber channel. Thus, a SimEvents based communication model is designed to simulate all the intermittent communication parameters. Along with this, a small-signal analysis of an autonomous inverter based microgrid considering the maximum time delay as the stability margin is investigated. Upon determining the time delay margin, the value of the delay is tested in MATLAB/SIMULINK environment to validate the stability margin from theoretical studies.
