Usually two states for microgrid use exist: it is either assumed that the microgrid can work in conjunction with – or can be islanded from – the national grid [[26], [27]], or the microgrid is operating independently because a national grid is not accessible [28]. While this is a generally safe assumption in choice examples, one of the major time-consuming and costly
