QUASI-DYNAMIC MODEL OF THE INTERCONNECTED POWER SYSTEM OF UKRAINE FOR A FREQUENCY STABILITY STUDY

Abstract

Significant integration of renewables into Ukraine's interconnected power system (IPS) requires developing the appro-priate quasi-dynamic (QD) model to study power system operation in such conditions. The work aims to create a QD model of the IPS of Ukraine considering renewables and consumption profiles of the Ukrainian IPS for the winter and summer character days. The corresponding approach to such a model development is presented in the paper. The load flow series simulation results based on the quasi-dynamic approach are also shown. Additionally, the frequency stabil-ity study results for the Ukrainian power system are depicted. Ref. 6, fig. 6.
