THE CONCEPT OF ENSURING THE STRONG SUSTAINABILITY OF UKRAINE'S ELECTRIC POWER INDUSTRY IN THE CONDITIONS OF TERRORIST AND MILITARY THREATS

ABSTRACT

To support the strong sustainability of the energy sector in the conditions of terrorist and military threats, the concept of structural variability of the electric power industry is proposed. Structural variability is defined as the power system's ability to form such a number of subsystems and electrical connections between them that enables the operator to control the structure of the system and, in this way, ensure the hard stability of the power sector in conditions of purposeful destructive actions. We proposed a model of distributed market management of a structurally variable electric power system. The model is based on the decomposition of a single liberalized market into an upper-level market and regional markets interacting with each other according to uniform rules.

KEYWORDS

electric power industry, hard sustainability, structural variability, market decomposition.

ABSTRACT

The article is devoted to the analysis of problems and experience of conducting research on the implementation of Smart Grid and Demand Response concepts in power supply systems with sources of distributed, decentralized generation and active consumers in power systems. The issue of finding ways to solve the scientific and technical problems of implementing the concepts of Smart Grid and Demand Response when solving the tasks of designing and building local electric power systems, taking into account the peculiarities of their functioning in the unified energy system of Ukraine was considered. The range of under-researched problems of decentralized management development in the retail segment of the electricity market in the organization of micro-markets based on the application of modern approaches of multi-agent management and block chain technology for the business processes organization is outlined. The main tasks of the conceptual design of the new market architecture of micro-markets on local electricity systems and their integration into the existing systems of organizational, operational-technological and information management of the electricity market are presented. Micro-markets are actually developing and, with experience, can become a driver for the post-war development of the market infrastructure in terms of the simultaneous implementation and practical application the Smart Grid and Demand Response principles for the implementation of technical solutions at the retail market level.

ABSTRACT

A model of the system for automated setting of network equipment security configuration is proposed. In order to improve the security configuration of network equipment, a set of existing security threats in modern information and communication networks was analyzed. It was determined that with the increase in the level of introduction of information technologies in the life of the individual, society and the state, the level of danger in the cyber space increases. The general trends of ensuring cyber security at all levels are considered. The types of threats to users are systematized and their properties are considered. Based on the results of the study, it was determined that the cloud approach is the most appropriate for infrastructure deployment. Cloud services are considered and approaches to the automation of infrastructure deployment are defined, which provide an opportunity to minimize errors in the configuration of the architecture.

USE OF BLOCKCHAIN TECHNOLOGY FOR BUILDING A HIERARCHICAL STRUCTURE ON MOST STATE REGISTRIES FOR THE PURPOSE OF PROTECTION AGAINST FORGERY OF INFORMATION

ABSTRACT

The work deals with the problem of ensuring the security of information storage in various registers, including state ones. First of all, we focused on security against attacks aimed at changing information in the registry, which is a constant and real threat today. The method proposed by us to prevent such attacks on changing information in the registry is based on the use of results from a relatively new direction in the field of information technology – blockchain technology. We propose building a so-called cascade structure of registers on blockchains using one of the newest consensus protocols called Proof-of-Proof. Such a cascade structure of registers, with the correct parameters of its construction and use, provides all the properties of correct information storage, such as non-failure, immutability, sequence of placement in the register, and others. After formulating the basic idea of building a cascade registry, we present a list of problems that need to be solved so that the probability of success of a substitution information attack is negligibly small.
