“…3) According to the proposed method it is possible to make a simple, but effective program for multichoice calculations, which automatically determines the minimum size of the model and provides the stability assessments for various regulator settings of the added node and topology of its communication with the system [2,3,4].…”

“…5. The Givens method is different from the previous one in that the majority of zero elements of the matrix are stored, whereby the latter has the form which is more favourable for decomposition [2,3,4].…”

“…At the same time extra subdiagonal elements tend to zero and blocks of 2 2 are formed on the diagonal. Determinant of each of such a block after subtracting of its diagonal elements of the unknown eigenvalue gives a quadratic equation with roots, which are eigenvalues; they can be complex as well [2,3,4]. Upon achieving the desired accuracy, we obtain the upper block triangular matrix C, the form of blocks, which easily can be determined by EV, as its determinant is determined by the product of determinants of encircled blocks.…”

The current stage of the world energy development is characterized by the creation of powerful territorial and integrated power systems. A gradual unification of the energy markets of different countries is currently going on within a free market: the configuration of networks has been changing, additional relations appear, new energy companies and unions are formed, a sector of renewable sources is rapidly developing with its characteristic distributed generation (decentralization), therefore, the most urgent matter of finding and creating new methods and algorithms for calculation and analysis of complex EPS. In particular, it concerns the issue of problem solving of large-scale power systems with a detailed accounting of basic elements of the system. All ongoing and planned changes both directly and indirectly affect the network configuration, which in its turn leads to the appearance of additional generation and load nodes and, consequently, it requires careful economic and technical computations, in particular, the static stability assessment of the power system.
