Islanding operation of smaller distribution networks (sometimes called microgrid) is one of the primary cause to trigger the cascading blackout, but it is essential to meet global energy access and net zero goals [].During islanding operation, load variation and fluctuations in power generation result in an energy imbalance.
Different from traditional utility grid, a microgrid contains DGs through VSC to interface with utility. The VSC have more controlled variables than the commonly used synchronous generators (Tan, So & Chu, 2010). Thus one of the key problems in microgrid operation is to determine control strategies.
