Abstract
The purpose of the study was to develop effective algorithms and strategies to minimize the negative effects of emergency power outages. A methodology had been developed that defines the steps and processes for efficient modelling and selection of optimal power grid switching schemes that can ensure the stability of power supply and increase grid resilience during blackouts in a particular city or region. As a result of the study, a power grid switching scheme was developed and improved for use in military and other crisis situations. Possible power outage scenarios were studied, which made it possible to consider various response options and ensure maximum efficiency and reliability of power supply during emergencies. Based on the data, and taking into account additional aspects of grid safety and reliability, the optimal power transmission routes and location of backup power sources were determined. In addition, a risk assessment was carried out to ensure stable operation of the system during crisis situations, which helped to increase its resilience to possible failures. The analysis of existing methods, such as manual switching of networks, use of automated systems and involvement of backup power sources, allowed us to identify the advantages and disadvantages of each approach to ensure stable power supply during a blackout in one city or region. As a result, it was found that by optimizing the grid switching scheme, the damage caused by blackouts can be minimized. The advantages and disadvantages of the different approaches were also identified, and the results of the study confirmed that the optimal grid switching scheme significantly reduces the duration of the blackout
