Olexandr Kyrylenko - Power Systems Research and Operation: Selected Problems

The series Studies in Systems, Decision and Control (SSDC) covers both new developments and advances, as well as the state of the art, in the various areas of broadly perceived systems, decision making and controlquickly, up to date and with a high quality. The intent is to cover the theory, applications, and perspectives on the state of the art and future developments relevant to systems, decision making, control, complex processes and related areas, as embedded in the fields of engineering, computer science, physics, economics, social and life sciences, as well as the paradigms and methodologies behind them. The series contains monographs, textbooks, lecture notes and edited volumes in systems, decision making and control spanning the areas of Cyber-Physical Systems, Autonomous Systems, Sensor Networks, Control Systems, Energy Systems, Automotive Systems, Biological Systems, Vehicular Networking and Connected Vehicles, Aerospace Systems, Automation, Manufacturing, Smart Grids, Nonlinear Systems, Power Systems, Robotics, Social Systems, Economic Systems and other. Of particular value to both the contributors and the readership are the short publication timeframe and the world-wide distribution and exposure which enable both a wide and rapid dissemination of research output.

Indexed by SCOPUS, DBLP, WTI Frankfurt eG, zbMATH, SCImago.

All books published in the series are submitted for consideration in Web of Science.

Ensuring operational reliability and safety of objects integrated power system of Ukraines complex task. Solution of which is related to the optimization of operating modes of electric power facilities and their control systems, information and measuring systems and metrological support in the electric power industry, ensuring the functioning of the electric power system in the conditions of a competitive market of the electric power.

Develop these areas, the monograph covers new technologies and methods related to the management of large interconnected power systems, solving a stable and reliable problem of electricity generation, ensuring optimal operation of transmission lines taking into account the probabilistic nature of corona losses, sources of electricity from renewable sources and energy sources. Devices with remote control, which is reasonable in the case of cyclical and long-term changes in load, as well as assessing the impact of transmission network constraints on electricity exchange in the context of integration of electricity markets into the European electricity market. So, the monograph can be divided into several main sections.

The main part of the monograph is devoted to the management of power systems. Total transmission power is an important indicator of any system interfaces used to maintain system stability in a market environment. Information about the total transmission power for power systems management used. In addition, total transmission power daily or even hourly to estimate the reliability margins for all power transmissions through the interfaces of each network. According to the proposed approach, users spend their time setting up and preparing big data for calculations. This approach significantly reduces the number of errors of operational staff when performing calculations. To optimize the modes of operation of the transmission line, proposed to solve problems of voltage and reactive power optimization. Power lines operating mode monitoring consists of correct choice of the composition of the charging power compensation devices in order to regulate the voltage levels and power coefficients at the bus terminals. By using modern devices for controlled compensation of power line charging, it is possible to achieve deeper regulation of reactive power and voltage, and, accordingly, to minimize the loss of active power. Interconnected mathematical models set to determine the economic effect of optimizing the mode of operation of the electrical network with ultra-high power lines in terms of voltage and reactive power, taking into account the probabilistic nature of corona losses. Methods, algorithms and methods of operative optimization of operating modes of separate power lines taking into account corona losses are developed.
