“…In general the majority of the literature focusing on resilience of a grid, look at microgrids as possible backups for the main, as also observed in [14]. A recent paper [15] provides a similar approach to ours, but the aim is to demonstrate that an hybrid microgrid configuration (diesel generators -DGs-supported by DER and ESS) is by itself more resilient than that only supplied by DGs.…”

This paper presents an original two-steps methodology to size DERs (Distributed Energy Resources) in stand-alone microgrids, to be installed in different areas, featuring different meteorological conditions, but same kind of loads. Design examples are simulated to analyze how an increased level of resilience, considered in terms of number of days of autonomy after an initial incident, affects the sizing of a PV field and its storage. A practical tool to support strategic choices is methodologically illustrated and applied to two case studies to find the best configuration, which is identified by a trade-off among fuel consumption, sizes of PV arrays and resilience. Key design parameters help in designing the best system according to the location, by focusing on the newly identified key performance indicator N P V s , the simplified net present value of specific scenarios of interest, where a penalty is introduced to account for less than the ideal target of autonomy. The model-based design used to create the microgrid simulations is validated by experimental measurements on a test-bed hybrid microgrid.

“…The scope of our work, instead, is to investigate further by considering how to assess the role that increased storage can play and how to trade-off among the many conflicting issues [16], expanding on what in [15] the authors show as a resilience concept, though differently defined: the hybrid microgrid.…”

“…Integration of the stand-alone emergency power systems (SEPS) in a building complex is a way to improve the reliability and reduce the total costs based on the concept of energy network (Cortés et al, 2020;Marqusee, et al, 2021a). By connecting stand-alone emergency power subsystems with a micro-network, the integrated emergency power system (IEPS) can cooperate and be backup for each other in the building complex.…”

Emergency power system refers to a system that is composed of self-generating equipment in the building. By providing power support for emergency events such as power outages, it can keep the energy safety assurance. Usually, emergency power systems are independent and redundant. As a backup, their utilization rates are extremely low, resulting in excessive redundancy causing a lot of waste of resources and equipment. In this paper, a model integrating stand-alone emergency power systems with micro-network was proposed to improve power supply reliability in a more economic manner. Integrated emergency power system with the dispatch strategy of self-priority was established based on reliability and power demand of buildings simulated through Monte Carlo method. To evaluate the impact of integration, the total cost of integrated emergency power system was calculated including economic loss during power outages and system costs. Finally, genetic algorithm was used to obtain the optimal capacity and dispatch strategy of the integrated emergency power system by minimizing the total cost. Results showed that the reliability was improved, and the total cost was reduced to 80.05% by integrated emergency power system in the illustrated case.
