Using the flexibility of EPS as a means of improving the system reliability of power systems in modern conditions

Scientific research in the field of EPS flexibility has recently been intensified, and this flexibility is considered in a fairly broad setting. It is important to note that the issues of EPS flexibility are not new, but the term “flexibility” was not used to refer to this issue before, although all the main issues were considered within the framework of the topic of system reliability and development of EES, and the issue of continuity of modern research with previous scientific research and existing scientific results is important. Traditionally, one of the aspects of system reliability has been the power security of the EPS, which refers to the ability of the system to withstand sudden disturbances without unintended impacts on electricity consumers. At the same time, the analysis of power security was mainly performed only in the volume of the system-forming power gird of the EPS. For the power systems of the future, the importance of power security increases significantly, but as an analysis of the power security of the system-forming and distribution power grids together. For a number of years, the authors have been engaged in research in the field of mode reliability using the method of calculating EPS modes taking into account discrete and interval characteristics of mode parameters. This method allows us to study the properties of controllability of power systems of the future in the required problem statement
