Finding an Optimal Structure of the Power System Multi-Agent Control by the Criterion of Local and Global Control Proximity
Domyshev A.V. (Melentiev Energy Systems Institute of the Siberian Branch of the Russian Academy of Sciences)
Abstract. The article suggests a new method of figuring out an optimal structure of the power system multi-agent control. The suggested methods of the multi-agent control are based on the distributed optimization task solution. The target control function may be presented as the sum of target functions that correspond to the control agents. The task is to find the optimal system structure that would provide the control close to ideal. The task of quick positioning in the average gradient field obtained as the result of the calculation series of the global (‘ideal’) target function has been solved. Along way, the problem of equal field mapping of the average gradient has been handled.
Keywords: multi-agent control, optimal control, mode optimization, clustering, power system.

POWER QUALITY
Power Quality in a Distributed Network with Integration of Solar Power Plants
Guo L., Vas’kov A.G. (NRU «MPEI», Moscow)
Abstract. This study examines the power quality (PQ) issues arising from the large-scale integration of photovoltaic (PV) power stations into low-voltage distribution networks. By developing a detailed simulation model, this work systematically analyzes the impact of three typical PV integration scenarios on key power quality indicators: voltage, frequency, three-phase voltage unbalance, and harmonic distortion. The results indicate that connecting PV systems to a single phase is the primary cause of a significant power quality degradation. While evenly distributing PV systems across the three phases can substantially improve certain parameters, risks of exceeding allowable voltage deviations and unbalance levels persist under high penetration scenarios. The ratio between the load and the generated power serves as a key factor determining the direction and the magnitude of voltage variations, and resonance phenomena are the main cause of non-linear deterioration of harmonic distortion.
Keywords: solar power plant, power quality, load-to-generation power ratio, three-phase voltage unbalance, voltage and frequency deviation.

Refinement of the Ice Melting Mode Calculation Methodology for Overhead Line Ground Wires Based on Experimental Determination of Modern Ground Wires Electrical Characteristics
Satsuk E.I. (JSC SO UES), Shevchenko A.V., Shevchenko V.A., Rychkov S.V. (EnergoSoftProekt, LLC), Berezkin E.D., Zasypkin A.S. (South-Russian State Polytechnical University (NPI) n.a. M.I. Platov)
Abstract. The refinement of the methodology for calculating ice melting modes on overhead power lines (OHLs) concerning modern overhead ground wire (OGW) designs is a pressing issue. A key obstacle to achieving this is the lack of information in reference literature and manufacturers’ technical documentation regarding the electrical characteristics of such wires. The article describes the methodology for conducting experiments to clarify the dependence of the active (R) and internal inductive resistance (Xin) of the OGW on the magnitude of the ß owing current, and also presents the results of the experiments within a current range of 20 A to 200 A, under the condition of a wire temperature of 0°C. The investigation is conducted using a custom-built test bench that simulates real-world operating conditions for the wire. The obtained results enable the updating of the ice melting mode calculation methodology within the «Gololed» (Ice Cover) family of software. This ensures an increase in the accuracy of determining the necessary ice melting parameters, thereby enhancing the reliability and efficiency of the ice deposit removal process on OHLs.
Keywords: electric power systems, overhead ground wires (OGW), icing, ice melting.

Abstract. The article introduces the results of studying the scientific publications on the operation of cable lines and overhead transmission line cable sections. The results of domestic and foreign research are structured, and the cable operation practice with the focus on cable termination reliability in conditions of extreme weather conditions is reviewed. The following key definitions are used in this article: a cable system is a combination of a power cable, joining and termination attachments, and a monitoring system; it is viewed as a unit in design, construction, wiring and operation; a failure is an event of an object malfunction. It is claimed that improvement of cable termination resistance to extreme weather conditions is one of the most relevant tasks of the present-day power industry. This conclusion is proved by the study of operational failures, as well as by the research conducted by teams in Russia, China, Norway, Italy, Sweden, Malaysia, Germany, Japan, Jordan and other countries. The extreme weather conditions is deemed to be a combination of climatic factors (absolute minimum temperature, duration of temperature below zero, diurnal temperature changes, wind and ice load, icing) that either exceed the set values specified in the standard certification tests or emerge with an abnormal periodicity, thus, leading to accumulation of degradation defects in the design of the cable termination.
Keywords: cable joints, cross-linked polyethylene (XLPE), failure, emergency, fault, extreme weather conditions.

Abstract. The study presents the development of a centralized fault location method for electrical networks based on synchronized phasor measurements and machine learning algorithms. The centralized approach improves fault location accuracy by utilizing synchronized phasor measurements from all equipped power facilities, thereby increasing measurement redundancy. The method was validated using both synthetic and physical data. Synthetic data was generated through electromagnetic transient simulations conducted on the IEEE24, IEEE39 and IEEE118 test systems. For validation with physical data, measurements from the actual power system facilities were employed. The conclusion summarizes the key findings of the research and outlines directions for future work.
Keywords: power system, fault location, synchronized phasor measurements, machine-learning algorithms.

Selection of Emergency Diesel Power Plant Capacity for Black Start of Combined-Cycle Power Plants
Asainov D.N., Shekari M., Pleshanov K.A.(NRU «MPEI», Moscow)
Abstract. Accidents and disturbances in power systems may require the startup of thermal power plants from backup power sources, such as emergency diesel generator units (DGUs). In Russia, combined-cycle gas turbine (CCGT) units are widely deployed; therefore, determining the startup conditions of CCGT units, which define the required capacity of an emergency diesel power plant (EDPP), is a relevant task.This paper presents the results of mathematical modeling of thermomechanical processes during the cold start of a 450 MW double-unit CCGT block (CCGT-450). When the gas turbine unit (GTU) reaches idle operation, the electrical loads of auxiliary motors within the plants thermal scheme are determined. This makes it possible to justify a reduction in the required total capacity of the EDPP.The obtained results on the composition and power consumption of auxiliary loads required for the black start of the CCGT-450 can be applied in the design and modernization of power plants, as well as in the restoration of power supply following beyond-design-basis disturbances, including extreme external impacts, through the deployment of mobile EDPPs for starting CCGT units at any node of the power system.
Keywords: emergency diesel generator unit (DGU), emergency diesel power plant (EDPP), black start, auxiliary loads of combined-cycle gas turbine (CCGT) plant, gas turbine startup, load on auxiliary load mechanisms.

Determination of Phase Shifts Between Currents and Voltages in a 0.4 kV Electrical Network to Analyse the Effectiveness of its Protection
Lansberg A.A. (Federal Scientific Agroengineering Center of VIM)
Abstract. The problem of detecting the emergency operating modes of a 0.4 kV electrical network caused by single-phase ground faults and various types of wire breaks is urgent. The phase shift angles between currents and voltages can be used to increase the reliability of recognizing the emergency operating modes of a 0.4 kV electrical network. The study of phase shift angle distribution between currents and voltages in the on-load and emergency operating modes of a 0.4 kV electrical network was implemented on a computer model, the prototype of which is a 0.4 kV 1000 meter-long radial overhead transmission line connected to a transformer with the rated power of 250 kVA. In the course of computer modeling, it was found that monitoring of currents and voltages combined with monitoring of phase shift angles between them can increase the reliability of recognizing the emergency operating modes caused by single-phase ground faults and phase wire breaks in a 0.4 kV electrical network. It has been revealed that the phase shift angles are not a reliable parameter that can be used to identify the modes of the neutral wire break in a 0.4 kV network and the phase wire break at the 10 kV side.
Keywords: modeling, computer model, emergency mode, short circuit, wire break, phase shift angle.

Deсentralized Voltage Emergency Control in Electric Power Systems with Application of Sensitivity Analysis
Matus D.V., Chemborisova N.Sh. (NRU «MPEI», Moscow)
Abstract. A current issue of maintaining the acceptable voltage levels and the load stability in complex electric power grids is considered. The concept of decentralized voltage emergency control with application of sensitivity analysis for selecting the control action locations is proposed. The obtained control action amounts demonstrate the effectiveness of the proposed method using simulations on a real network fragment. The proposed system concept allows for prevention of load instability and compensate the excessive control actions by automatically reconnecting the load.
Keywords: emergency control system, load stability, voltage sensitivity of nodes, automatic voltage reduction limitation, balance-conductivity method.
