Features of design and implementation of advanced adaptive emergency control systems for power systems

It is shown that there is an evident need in Ukraine for the development and application of fundamentally new devices for emergency control of power system modes, particularly by leveraging international experience in the field of digital transformation of power systems based on adaptive algorithms. Based on the analysis of the evolution of the design and application of Emergency Control systems, the features of developing modern advanced adaptive Emergency Control tools for power systems are considered, aimed at increasing energy resilience during wartime and the post-war economic recovery of Ukraine. Principles for constructing advanced adaptive Emergency Control to ensure power system stability are proposed; these monitor the stability margin of the current mode and determine the control actions required to meet regulatory requirements regarding both active power in tie-lines and voltage at load centers. It is determined that synchronized measurements of voltage phase angles are of vital importance for solving the tasks of assessment and diagnostics of power system modes and the Integrated Power System of Ukraine as a whole. The practical acquisition and use of these measurements became possible with the implementation of the “Regina” hardware and software complex. The results of constructing the first advanced adaptive Emergency Control in Ukraine for the Ivano-Frankivsk energy hub are presented. During the Emergency Control design and system mode calculations, the impact of Renewable Energy Sources with an installed capacity of 1,253 MW was taken into ac-count. The modified “Regina” complex features intelligent electronic sensors (remote modules) of a distributed intelligent analog signal input system, noise-immune discrete signal input modules, and improved data processing algorithms, including data visualization.
