The aim of this work is to develop the assessment methodology with the use of an algorithm based on a flowchart of the system. The research methodology includes an analysis of the non-steady state phenomena with use of a MATLAB-Simulink environment and an analysis of the steady-state phenomena based on the theoretical calculations and analytical models of a combined cycle plant of the COGES type, connected with the processes of producing and converting of thermal and electrical power in the considered systems. A key point of the study is to check that the voltage frequency modulation on the shaft of the gas turbine is included in the limits defined by the appropriate requirements of the related IEEE Std 45TM-2002 standard. }, e-issn={2541-2486}, publisher = {Gdynia Maritime University}, keywords = { combined cycle plant, non-steady state phenomena, steady-state phenomena, analytical models, simulation research, electrical power quality, impact assessment}, doi = {https://www.doi.org/10.26408/111.06} }
