Design, research and operation of the Intellectual Power System (ISP) with the Active Adaptive Grid (AAG) (also known as Smart Grids) demands that one solves a large number of sophisticated problems. Engineering solutions that are being developed and equipment used for that are new not only to the Russian energy industry, but to the global practice as well. Therefore their implementation requires a thorough analysis and, in most cases, an individual approach and research studies that ensure not only that the desired technical and economic effect is obtained, but also that the new elements that influence the power system in general are assessed. The use of incomplete or improbable information about the regimes and processes in power systems can lead to false design and operation solutions in real ISPs, which, in its turn, can lead to severe system incidents related to significant technical and economic damage. Due to the known specificity of the ISP with the AAG, the only way to obtain such information is by way of mathematical modeling. It all imposes heightened requirements upon the used tool and research methods when solving such tasks. This work describes a new approach to modeling the ISP – a concept of hybrid modeling. According to this ideology, several methods (analogous, digital (numerical) and physical ones) are combined in order to ensure high adequacy of such modeling. The analogous part ensures that there is no systematic error of integration. At the software level, the digital part allows implementing algorithms of control and parameter variations of the reproduced power system. At the physical level, one ensures the connection and commutation of the simulated elements which is similar to how it is carried out in a real power system. Apart from the details related to the concept of hybrid modeling, the article presents instrument peculiarities of the implementer of this concept – a real time hybrid modeling complex of the ISP, an alternative to the digital modeling complexes which are currently used.
