This paper is the final article in the series devoted to the study of resilience of isolated local-level energy complexes or autonomous microgrids using the previously developed technology of a digital twin of a complex technical system. By resilience we mean the property of these energy complexes to adapt to large perturbations and restore their initial state after their impact. The study of resilience of these energy complexes of local level is usually based on multivariate computational experiments, however, if there is feedback of the digital twin with a microgrid or test bench, it is possible to use field experiments. The two-way communication between the digital twin and the microgrid is provided by a specialised subject-oriented environment. The paper demonstrates the application of the previously described methodology for assessing the resilience of an autonomous microgrid by analysing the vulnerability of the power supply system of a hypothetical tourist camp conditionally located on the shore of Lake Baikal and having no connections with external power systems. In particular, we searched for critical elements of this microgrid, consisting of photovoltaic converters, accumulator batteries and a diesel-generator set from the point of view of resilience. The computational experiments carried out showed that the critical elements of a given microgrid are the diesel generator set and the batteries. Further development of this work is seen in the improvement of methods and tools for the design of digital doubles of autonomous microgrids.
