The Structural and Parametrical Organization of Elements of a Power Supply System in the Conditions of Network Centrism

Abstract

Purpose. Development of indicators of the structural and parametrical organization of effective active and adaptive system of service of power supply systems in the conditions of ideology of Smart Grid. Methodology. In the conditions of application of ideology of Smart Grid for increase of intellectualization of electrical power system there is a need of introduction of the principle of a network centrism in the structural and parametrical organization of elements of power supply systems that involves performance of conditions on implementation of provisions of the principle of Situational Awareness. The essence of this principle consists in that, information on a condition of system has to be presented in the form convenient for the analysis, recognition, transfer, distribution and storage, to be coordinated for flexible and optimum development at the subsystem and object-by-object levels. Results. Structural and parametrical optimization of elements of power supply systems in the conditions of a network centrism and the concept of SG involves use of provisions of the theory of systems and concepts of multicriteria optimizing synthesis. It is offered to use the modified adaptive indicator of the generalizing effect of synthesis of structure of active and adaptive system of service of power supply systems in the form of a difference of the generalizing effects: the introduced option of structure of system and basic. Originality. Introduction of an adaptive indicator of synthesis of system of service of power supply systems considers the concept of «service of system on the basis of a response» in the presence of false and true refusals. Practical value. Use of the specified indicator will allow to specify procedure of selection of competitive options for the purpose of definition of a set of admissible structures which meet the requirements of criterion function.

In the electric power system of the world and Ukraine is not the first year they are working on the «intellectualization of networks» -Smart Grid (SG). Currently, the ideology of building of intellectual energy networks the SG [1] (a term is introduced by Michael T. Burr in 2003 [2] -one of the most significant and developed at the modernization of the global energy industry. In the US and Western Europe, a number of large and more smallscale projects for the transition of power indust...

The Development of the Theory of Instantaneous Power of Three-Phase Network in Terms of Network Centrism

“…Solving the problem complicates the presence of weak and at the same time extensive information and management connections in large areas [2].…”

Network-Centric Technologies for Control of Three-Phase Network Operation Modes

“…System processes of intellectualization of Ukrainian electric power system are based on the introduction of Smart Grid technologies. The value of this technological transformation is to redistribute the demand for electric power at the moments of maximum load, to reduce additional investments in the reorganization of the power system in order to increase its productivity [1]. Multilevel development of the control system of the operation modes of a three-phase network implies the use of the principle of network-centricity -the control of heterogeneous objects of the energy system infrastructure in a single information and communication management space due to the formation and maintenance of a single integrated contextual information environment for all tiers [2].…”

“…One of the ways to achieve these management objectives is to introduce into the system of operational maintenance of the power system [1], in addition to the distributed subsystem of digital measuring modules, a group of unmanned aerial vehicles (UAV) for monitoring the state of a three-phase network [3]. Multi-agent technologies for the collection and transmission of information using UAVs ensure the continuity of acquisition and the relevance of the contextual information image of the three-phase network.…”
