“…Emergency response systems must be ready to take immediate action to prevent a humanitarian crisis and ensure the safety of citizens. In addition, the effectiveness of the crisis management system is determined by the level of interaction between different branches of government, local authorities, energy companies and other stakeholders (Ostudimov & Kaminska, 2023). It is important to have communication and information exchange mechanisms in place to respond quickly to any challenges that may arise as a result of a long-term electricity shortage.…”

Due to the deteriorating condition of the power grids and the increasing number of power outages, research on technical solutions to prevent blackouts in the Ukrainian energy system is becoming an extremely relevant and necessary task. This study aims to analyse technical solutions aimed at increasing the resilience of Ukraine’s energy system to prevent blackouts and ensure reliable electricity supply to the population. The methods used include the analytical method, classification method, functional method, statistical method, synthesis method, and others. The study analysed modern technical solutions to improve the resilience of the Ukrainian energy system. The study included a detailed analysis of innovative approaches to modernizing the energy infrastructure. The primary objective was to study and evaluate modern technologies for designing new power lines with improved transmission characteristics. The study emphasized the importance of expanding automation systems to effectively monitor and control the state of the power grid. The study also identified the importance of using energy storage, developing renewable energy sources and improving electricity consumption forecasting systems. Flexible load management measures and improved cybersecurity systems were identified as critical. It is noted that the implementation of the project to provide electricity to the conditional area will be a key step in improving the lives of the local population and providing the necessary conditions for the development of the area’s infrastructure and economy. In addition, the operation of generators for electricity supply will help to reduce the feeling of lack of electricity among residents and ensure reliability in the use of electricity for all sectors of the district’s economy. The overall conclusion is that the implementation of such technical solutions will significantly increase the resilience of Ukraine’s energy system. The results obtained make it possible to effectively avoid blackouts and ensure a sustainable electricity supply to the population. This allows energy companies, government agencies and other stakeholders to optimize energy resource management and make informed decisions to ensure the sustainable and efficient operation of Ukraine’s energy system in the face of a possible blackout risk

The relevance of the study is to develop an effective system for controlling the pressure in the air supply in motorised breathing apparatus to ensure effective protection of employees from dangerous aerosols and improve their health. The goal was to create an automated air pressure control system in a motorised breathing apparatus using a proportional-integral-derivative controller. For this purpose, the simulation method was used. In order to avoid unforeseen situations of deterioration of the level of protection, the structure of the pressure control system of a motorised respirator has been developed with the selection of the appropriate controller based on the obtained dependences of the influence of the parameters of the breathing mode and the amount of pressure in the under-mask space of the respirator, which ensures an appropriate comfortable mode of operation. This allowed developing a simulation model with a PID controller that would provide the appropriate pressure values within the permissible limits (50-370 Pa). It is proved that the proportional-integral-derivative controller maintains the pressure in the respirator mask within certain limits both with an increase and with a decrease in the control signal, preventing excessive fluctuations in the controlling variable, which leads to an extension of the service life of the filter elements and a reduction in electricity consumption for the operation of the fan motor. Based on modelling the operation of the pressure control system in different modes of operation, it is shown that when using a PID controller with defined parameters, the system provides compensation for changes in air

In modern conditions, military conflicts are becoming more common, which makes it relevant to examine their impact on the country’s economy in all possible ways. The purpose of this study was to investigate the situation in the energy industry in Ukraine and other countries of the world in connection with the beginning of a full-scale Russian invasion of Ukraine. The main methods used in the study were analysis, systematisation, and comparison. The paper showed the role of the energy sector in ensuring national and global stability. It was concluded that military conflicts have a significant impact on the stability of this sphere, both in the warring country and in other states that may not be directly involved in the conflict. At the moment, there is a limited amount of statistical data available that can be used to assess the impact of Russia’s military actions on the energy sector of Ukraine. However, based on the available data, it was concluded that their impact is significant and can lead to major problems in the future if there is no decisive action at the moment. During the first attacks of 2022, this has already caused a shortage of energy and blackouts. As part of the study, quite a few approaches were proposed on how to overcome the consequences of military conflict in the global and national energy markets. In particular, the need to develop diversified energy supply routes, increase the use of renewable sources, ensure international cooperation and attract international investment in the industry was noted. The conclusions drawn in the framework of the study allow increasing the effectiveness of the national energy policy in Ukraine, given the military situation in which the country finds itself
