Abstract
The article considers methodological and practical aspects of scenario studies of the problem of ensuring energy security of Russia and its regions. It describes various approaches toproviding energy security, validates the use of energy securityindicators as specialized criteria for assessing the level of energy security of the territories. For scenario studies, the requirements for the composition of scenarios are formulated; mandatory steps of computational experiments, namely a flexible preliminary and expert analysis of the calculated states and its multicriterion natureare described. A brief description of the basic model of studying the country's fuel and energy complex is also given. The main emphasis in the article is on the technology of conducting research using methods of combinatorial modeling. Within the framework of this material, a practical assessment of the importance of combinatorial methods in the above mentioned field of research is given, and the scheme of their development is described. The concept of combinatorial modeling methods application in energy security studies is clearly reflected in the ontological representation. Instrumental support of combinatorial studies of energy security is described in a separate section of the article. It describes the distributed package of applied programs "Corrective" used for research on reliable fuel and energy supply of territories. In the description, the key provisions for the implementation of the "Corrective" technical and methodological character are formulated. In particular, a graphically oriented representation of the calculated states and structures for specifying research scenarios is designated and typified, the algorithmic apparatus (combinatorial modeling methods, cluster analysis, algorithms for determining optimal states and trajectories of the fuel and energy complex development) is described, the orientation of the program package toward distributed computingis emphasized.. Also, technical details of the "Correctives" implementation (its architectural solutions, development tools) are also included in the description. In addition, the technology of analyzing the functioning and development of the country's power engineering in terms of ensuring its energy security is presented.
