ABSTRACT

A review and analysis of publications devoted to solving scientific and practical problems of the development of the electric energy (e/e) market as a complex organizational and technical system (SOTS) is given. The subsystem of pricing management is highlighted, as its component part, as a separate object of organizational management. The urgency and necessity of creating a simulation model of the system for managing the pricing process in the electricity market with the direct participation of market entities is substantiated, the main purpose of which is to study the scientific and practical problem of improving the methodological pricing tools. Based on the analysis of modern methods of simulation modeling of management processes in the SOTS, the choice of a multi-agent approach as the main one for building a simulation model of pricing processes in the electricity market is justified.

KEYWORDS

simulation model, multi-agent approach, organizational and technical system, electricity market.

ABSTRACT

A retrospective approach to building a model of electricity generation of Wind Power Plants (WPP) and Solar Power Plants (SPP) was applied. In this approach, data on electricity generation by WPP and SPP of previous periods are considered as a reflection of complex processes of conversion of variable wind energy and solar radiation by available generating equipment for electrici­ty.The model is presented in such a mathematical form, which in the forecast period allows to take into account the impact of future climate change and the dynamics of the introduction of new capacities of WPP and SPP on the functioning of the electric power system. This model is easy to apply and ensures the adequacy of modeling the development of electric power systems with dif­ferent shares of electricity production from Renewable Energy Sources. The results of application of the proposed retrospective model of electricity generation by WPP and SPP for modeling the deve­lopment of the electric power systemin accordance with the scenario of the Energy Strategy of Ukraine for the period up to 2035 are presented.

KEYWORDS

ABSTRACT

The adaptive robotic system creation concept of difficult spatial forms metal parts restoration in which technology of an electric arc surfacing is used is offered. Arc surfacing implementation on the basis of industrial robots equipped with means of adaptation can significantly improve the quality and productivity of parts restoration while reducing the cost of energy and welding materials. The paper uses both theoretical research methods — analysis, idealization and formalization, and experimental — simulation. The solution of the repair CAD workpiece model identification problem and the installation adaptation implementation are considered. The robotic system adaptive capabilities are realized with the help of non-contact means of technical vision a triangulation laser-television sensor. The work results can be used in the areas of adaptive robotic restoration creation by electric arc surfacing in the engineering, railway and energy industries.

KEYWORDS

metal parts restoration of complex spatial forms, electric arc surfacing, robot manipulator, triangulation laser-television sensor, installation adaptation, CAD workpiece model.
