Development Of Software–Hardware System for Real Time Simulation of Electric Power System with Smart Grids

Abstract

The design and research of electric power system (EPS) with smart grids (SG), which are the current world trend of modern electric power industry, requires solving a large number of non-trivial tasks. The developed technical solutions and used equipment are novel for the world practice. Therefore, their implementation requires careful analysis and an individual approach to research that provides an assessment of the impact of new network elements on the power system. All of this puts requirements on the tools and methods of research used to solve such problems. At present, digital systems for modelling EPS with SG based on the application of numerical methods are used as such tools. However, despite the high level of these developments, it has drawbacks. The use of incomplete and invalid information obtained by digital tools can lead to the wrong design and operational decision in real power system, which can cause blackouts. The alternative approach for solving the problem of detailed simulation of EPS with SG is the creation of hybrid system based on the principle of combining different modelling methods. Hybrid Real-Time Power System Simulator (HRTSim) is developed based on this approach and presented in the paper.
