The article dwells upon optimizing, reduction of losses in, and improving the stability of grids by implementing devices that affect the parameters and power flows in a grid. State-of-the-art technology for better control is crucial for the development of electric power systems. FACTS technologies or flexible alternating current transmission systems, essentially transform the grid from a passive electricity transport into a device that actively controls the grid parameters. The article analyzes the development of a 500/220/110 kV grid that uses parameter-affective devices: SVC, BSK, LCD. Steady-state parameters, active power losses, and electric power losses were calculated for a year before and after the devices were deployed. Each device was therefore analyzed for effectiveness. The parameters of the SVC-equipped 500/220/110 kV grid were calculated for emergency operation with the 500 kV line being offline. Thus, the paper also analyzes the emergency performance of the SVC.
