AbstractDue to the growth of renewable resources in electrical power systems, it is essential to study and analyze possible events that impact the safety of the system. One of these abnormal events is the islanding of distributed generators. The islanding consists of an isolated operation of distributed generators and their respective loads, hence, part of the system is disconnected from the utility, but still in operation. This operation can bring numerous negative consequences: both for the electricity grid and its equipment, as well as for operators and users of the network. It is of great importance to adopt effective and safe island detection methods. Therefore, this work aims to analyse and evaluate common methods of anti-islading protection considering multiple distributed generators in low voltage, from the simulation of an IEEE 13-bus system with two wind farms and one photovoltaic power plants using MATLAB/SIMULINK.
