Abstract
Calculation of electromechanical transients and the stability of large, complex electric-power systems, even given a significant computing capacity, is a computationally complex problem, the solution of which is time-consuming, and, in some cases, for a large-scale system, this problem is unsolvable. This paper presents an approach to developing the equivalent of a global energy network for calculating transient stability. The dynamic equivalent of a large-scale electric-power system obtained using the method of coherent-group-generator reduction and network reduction, can significantly reduce the scale of the problem under consideration and obtain a solution using well-known software and computing systems. The creation of a dynamic equivalent of a global-energy-network is a daunting task, which requires data on all the power systems composing the energy network, which it is also a difficult task to collect. For a qualitative assessment of the power-network stability, the parameters of the dynamic equivalents can be calculated from the generalized indicators of power systems.
