Background
The workshop focuses on sustainable and resilience of energy sector as an important part of critical infrastructure. Modeling & simulation of the electric power grid in military threats is a significant part of the workshop. New methods, such as big data analysis, modeling & simulation, decision making & forecasting techniques, and artificial intelligence, are being implemented in the energy sector to not only improve efficiency but also bolster system resilience. The main goal of this workshop is to bring together experts, professionals, and enthusiasts in the energy sector to highlight how such data tools can be used to improve the resilience of energy systems. The tasks for the workshop are to show use cases of software and hardware solutions in energy systems for various countries, to find ways for improving sustainability and resilience of the energy taking into account the countries specifics, to define methods of energy sector reconstruction, and to show how to improve the cyber-attacks resist and others.

Ensuring a reliable, secure and affordable supply of electricity is essential for economic growth and development. Typically, the electric power system (EPS) is under constant threats from a number of natural, technological and anthropogenic actions, which can cause anything from power outages to chronic power supply shortages. For energy policy makers, designers and system operators, the problem of protecting power systems is extremely important, and is addressed by planning and investing in increasing the resilience of the power sector.
Comprehensive energy sector resilience planning involves identifying shock threats and stress loads on the energy system, as well as opportunities to prepare and adapt to them. Energy system resilience planning involves developing a strategy to mitigate such threats. The stability of the energy sector is ensured by organizational, technological and technical solutions to the problems of stability, robustness, resilience and durability of the EPS.
As a sector of economic activity, the energy sector as part of the EPS and the system of organizational and technological management and response is sustainable only in the conditions of untargeted actions of shock threats and stress loads.
Targeted terrorist and military threats to the energy sector are observed and implemented in many countries of the modern world. The exceptional nature of the action of such threats is due to the purpose of their planning and implementation – the destruction of the integrity of the EPS and the formation of energy islands with significantly limited or completely absent opportunities to produce, transmit and supply electricity to its consumers. Under such circumstances, the set of technical solutions to the problems of stability, robustness, durability and resilience of the EPS is not sufficient to ensure the stability of the energy sector.
The stability of the energy sector in the face of terrorist and military threats must be supported by organizational, technological and technical solutions to another problem – the problem of the structural variability of the EPS.
Structural variability is the ability of the EPS to form such a number of subsystems and electrical connections between them, which enables the system operator to manage the structure of the EPS and, in this way, ensure the strong sustainability of the energy sector in conditions of targeted destructive actions.
Decarbonization is a relevant strategy for the development of the EPS of many countries around the world. In the conditions of destructive military actions, such a strategy for the development of the EPS is not self-sufficient. Another energy strategy needs mandatory implementation – the construction of a structurally variable EPS, that is, one whose purposeful damage does not lead to long-term blackouts of large groups of consumers.
The construction of a structurally variable EPS of the country must begin at the regional level. In each regional EPS, technologically different electricity generators, as well as energy storage systems should be installed, the total capacity of which is capable of ensuring the production of electricity in volumes sufficient for consumption by the population, housing and communal services, transport and agriculture of this region. Provision of electricity for own regional production of the specified categories of consumers allows to maximally protect the life activity of each region from the impact of destructive actions aimed at the EPS of the country or at individual regional EPS.
Development of mathematical models of regional EPS and models of structurally variable EPS of the country is a necessary condition for planning their optimal development.
A feature of EPS mathematical models is their presentation in the form of large dimensions mixed-integer linear programming problems. The existing high-performance software solvers are oriented for use in single-processor computer systems and are not able to provide solutions to the current problems of modeling the development of the EPS in an acceptable time.
Computational experiments conducted to solve the problems of forecasting the development of generating capacities of regional EPS demonstrate the need to reduce calculations time.
The further development of mathematical models of regional EPS and the model of the country’s structurally changing EPS necessitates creation of a parallel simulation environment for solving current scientific problems of sustainable development of the electric power industry in the conditions of terrorist and military threats.
