description: This work is devoted to the study of the effect of frequency change on the results of calculations of steady state (SD), as well as the effect of frequency change on the allowable active power flows in controlled sections in isolated electric power systems (EPS) using various measures to improve static stability. The research set the following goals: 1. Analysis of the methodology for calculating the SD of the operation of the EPS, taking into account the change in frequency. 2. Simulation of the simplest isolated EPS. 3. Comparison of the results of calculation of the SD of the simplest EES without taking into account the frequency deviation and taking into account the frequency deviation. 4. Simulation of the EES of Primorsky Krai. 5. Determination of permissible active power flows in controlled sections of a real isolated EPS without taking into account the frequency deviation and taking into account the frequency deviation. 6. Analysis of the influence of frequency accounting on the static stability of an isolated EPS. The objects of study in the work: the simplest four-node EPS, isolated EPS of Primorsky Krai, which is part of the Unified Energy System of Russia (UES of Russia), being part of the United Energy System of the East (UES of the East).On the basis of the simplest EPS, it was proved and demonstrated that in the post-emergency state (PES), taking into account the change in frequency significantly affects the generation, value and direction of power flows. When analyzing the influence of frequency accounting on the static stability of an isolated EPS, significant differences were also revealed in the results of SD, taking into account the frequency change and without taking into account the frequency change. Modeling and analysis were carried out using the software-computer complex (SCC) Â«RastWin3Â». As a result of the work, it was concluded that the calculations of electric power SD and static stability in isolated EPS must be carried out taking into account the change in frequency.
