Abstract. The adoption of renewable energy sources in the energy system introduces uncertainties on the generation side. The need to take account of these uncertainties in managing the electric power system (EPS) makes the assessment of its flexibility one of the essential objectives of operational dispatch control. The paper presents a deterministic method for assessing the flexibility of the EPS planned operation with the energy storage system. The method is based on the assumption that EPS is flexible if the power balance is maintained during the considered time in planned and unplanned situations. First, we calculate the combination of powers at the load nodes, which, when exceeded alittle, make the EPS unable to maintain the power balance (i.e., the EPS loses its flexibility). This problem is solved as a linear optimization problem. The optimality criterion is represented by the maximum deviation of active load values from the planned ones, given the set constraints. Then, the EPS flexibility is calculated.
Keywords: flexibility of the electric power system, deterministic methods, optimality criterion

Selection of Prosumers in the Structure of the Demand Response Aggregator by Analytical Methods

Kolosok I.N., Korkina E.S. (ESI SB RAS, Irkutsk)

 

Abstract. Traditionally, power plants play the main role in maintaining the balance of power and energy in EPS. In the modern conditions of the development of the electric power industry, a new top requested instrument for regulating the balance of supply and demand in the electricity markets has appeared – Electricity Demand Response (DR). Based on materials from available sources, the article analyzes the criteria for selecting participants in the structure of the DR Aggregator within the framework of the DR Aggregator pilot project. It is proposed to consider the selection process both taking into account the requirements of the Aggregator for the reliability of the participants’ functioning, and taking into account the capabilities of the participants themselves, considered in the article from the standpoint of acyber-physical system.
Keywords: demand response, DR aggregator, cyber-physical system

Abstract. Today, the digitalization of the fuel and energy sector all over the world has led to the active and almost universal digitization and platform service implementation, and in most developed countries it is even included in priority national development programs. Such an active transformation of the industry revealed new problems, among which one of the main ones were the problems of the continuous growth of data volumes and the need for new approaches to their processing and analysis. The authors of this paper have quite a lot of experience in the development and implementation of decision support systems based on machine learning algorithms in various tasks of the power industry, and in the presented paper they tried to aggregate all their practical experience to analyze the main errors and the consequences of their influence on the results of the operation of such systems in the power industry. The paper also describes examples of the interpretation of the results, both in terms of data processing, and more importantly, in terms of their interpretation for the power industry.

Abstract. At present, in order to automate and informatize processes in distribution electrical networks (RES) with a voltage of 0.4 kV, new technologies have found wide application in the form of automated control and metering systems for electricity (ASKUE). However, in the composition of these information systems, there are no technologies focused on solving diagnostic problems. The article proposes methodological and algorithmic foundations for constructing a subsystem for diagnosing the states of wires of main lines of RES. The criteria for diagnostics are formulated based on the assessment of the level of their wear. The research results are aimed at improving the existing AMR and increasing the reliability of distribution networks.

Development of a Methodology for Assessing the Reliability and Priority of Repairs for Electrical Equipment of the Oil Industry Taking into Account the Possible Risk

Romanov V.S. (SamaraNIPIneft, Togliatti State University), Goldstein V.G., Vasilieva N.S. (Samara State Technical University)

 

Abstract. Domestic oil production enterprises (PE) are currently actively using risk-based management of submersible electrical equipment (SEE) as their main production assets. This, first of all, is determined by the natural quantitative growth of SEE and, accordingly, information about its parameters. However, both in general, with the current management of SEE modes, and when planning repairs, in particular, information about its state is not fully taken into account. This is manifested in the greatest way in determining the risk of emergency failures of electric submersible installations (ESI), taking into account the criteria for controlling the mode and the technical and economic efficiency of the SEE. A complex indicator is proposed for ranking objects in the SEE park based on information about their reliability in determining the risks of emergency failures. This allows you to set priorities when planning repairs and managing the operational modes of SEE.

Magnetoelectric Motor-Generator of an Autonomous Mobile Object

Abstract. One of the trends in improving power installations of standalone facilities is integration of starter (motor) and generator functionality in one electrical machine. This provides saving of costs for active and constructive materials of integrated electromechanical converter and semi-conductive power supply equipment. Considerable reduction of weight and overall dimensions is a really great result for the majority of standalone facilities (electric vehicles, special transportation means, electric start and generation systems of above-ground gas-turbine motors). Use of permanent magnets with high energy density for inducing the main magnetic flow in such machines makes this trend even more beneficial. However, limited possibilities of flow adjustment in permanent magnets cause big problems related to peculiarities of operation of the electrical machine in motor and generator modes. Required rated voltage, r.p.m., motor and generator torques could be different in several times. Some aspects of providing such contradictory demands in the magnetic-electrical motor-generator with different types of rotor design and stator winding diagrams are considered in this article. The results of digital simulation of electromagnetic processes enable reasonable choice of the inductor type and the winding diagram.
