A comprehensive approach to reliability optimization of power supply to consumers in power interconnection with weak tie lines

... components, optimal for the criterion of reliability and planning maintenance of generating equipment optimal for economic criterion. This approach makes it possible to use for reliability the main means available in the conditions of functioning of electric power systems (EPS) – reserves of generating capacity and planned maintenance of the main equipment. At the same time, reliability optimization is carried out taking into account the interests of different subjects of relations at the management ...

Prediction of the power shortage in the electric power system by means of regression analysis by machine learning methods

... learning methods // E3S Web of Conferences. Т.114. ID: 03003. 2019. DOI: 10.1051/e3sconf/201911403003 Modern electricity consumers place increasingly high demands on the level of reliability of power supply and, correspondingly, the reliability of electric power systems (EPS). These requirements should be directly addressed in the EPS development planning tasks. To this end, the evaluation of the level of EPS reliability is performed by employing software and computer systems that have various ...
