FACTS controllers can boost the effectiveness of power systems by continuously controlling the power system parameters. This work presented the allocation of Flexible Alternating Current Transmission Systems (FACTS) devices based on a new algorithm called the Improved Gray Wolf optimizing Method (IGWO). The proposed approach introduces the various FACTS controllers’ optimum location and size to mitigate the real power losses, bus voltage deviations, and system operating costs. The thyristor-Controlled Series Compensator (TCSC), Static Var Compensator (SVC), and Unified Power Flow (UPFC) devices have been used as FACTS devices. A comparative study was performed with other heuristic optimization algorithms, such as Grey Wolf optimizer (GWO) and Simulated Annealing (SA) algorithms, to verify the suggested algorithm’s effectiveness. Computer simulation has been applied to the IEEE 30 bus system. Conversion curves and detailed numerical simulation results have shown that the IGWO technique is superior to the comparative algorithms.

The high-frequency corona discharge-based ETRO-02 plant produces ozone and disinfects and cleans polluted waters. Cleaning of polluted water from impurities of petroleum products, phenol, hydrogen sulfide, cyanides, etc., using ozone gas (O3) as an oxidizer. Due to its strong oxidizer, ozone has a very high ability to break down organic substances, etc. impurities in aqueous solutions. Compared to the chlorination method, this ozonation method has many advantages. Firstly, Ozone can be obtained by installing ozonizers directly at the place of water purification and using the process of electric current disconnection from oxygen in the air. Secondly, chlorination in some cases leads to the formation of harmful substances in drinking water, including mutagens and carcinogens (copper, dioxin), so it is preferable to use the ozonation method instead.

The main goal of any power system is to ensure the demand for electricity from all consumers. The ability of the power system to provide power supply to consumers is characterized by its system adequacy. In most countries, the acceptable adequacy level is between 3 and 35 deficit hours per year. At the same time, there are deficit power systems in which proper adequacy level is not provided. The paper analyses the operation of the electric power system in deficit mode. This problem is considered in the example of Lebanon, which has been in such mode for several decades. The paper describes the technical condition of the power system and climatic, geographical, and social conditions in which it operates. The analysis of renewable energy potential is performed. Based on annual climatic data calculated three scenarios for renewable power sources commissioning in Lebanon. Power balance is analyzed in presence of renewable power sources of different capacity. Defined capacity of wind and solar power generation that can be installed in Lebanese power system without special control systems and energy storage for their operation.

Nowadays distributed energy is one of the breakthrough concepts for the development of the fuel and energy complex, however, there are some difficulties and risks for realizing some of its prospects. Thus, it is necessary to consider aspects of the implementation of distributed generation systems in the Unified Energy System of Russia and in isolated energy systems on its territory. The presented work is based on a comprehensive analysis of statistical data and events in connection with the development of distributed energy. Forecasting using dynamic indicators has also been used.

A variant of the algorithm for the automatic compilation of balances of electric networks capacities of a separate structural division is proposed. The algorithm is implemented in a software package developed by the authors and used to calculate the steady-state modes of electric networks. For a test design scheme, the transmission lines between structural divisions and indicators of power balance were determined and also structured power flows by voltage levels. The conclusion is made about the possibility of using the proposed algorithm in the calculation and justification of technological losses of electricity when it is transmitted over electrical networks.

In this research we have installed a computer vision system on a single board computer named ODROID™ XU4. This project is a modification of a more complex and bigger system – the robotic cash counting area. Before our modification a trained neural network was installed on a single board computer, but this caused the computer’s CPU (central processing unit) to be overloaded and soft was shutting down. We implemented and compared two methods of object detection in an image and video, namely Shi-Tomasi and FAST (Features from Accelerated Segment) methods. The comparison criteria were accuracy of detection and CPU load.

The article describes the economic efficiency study results for several modernization cases of existing power equipment. The modernization cases assume the Pressurized Heat Recovery Steam Generator (PHRSG) usage with the twostage gas turbine. The T-100 cogeneration steam turbine and the K-300 condensing steam turbine were selected as the modernization object. The modernization cases are carried out with the high-power SGT5-2000E gas turbine and low-power GT-25PA gas turbine. New combined cycle gas turbine (CCGT) power plant construction case is considered for comparison as an example of typical Russian modernization case. The main economic efficiency indicators were considered - net present value (NPV); internal rate of return (IRR); pay-back period – simple (PP) and discounted (DPP); profitability index (PI). The article shows that all cases are investment attractive, but each case has its own specifics.
