The optimization of abnormal modes of electric networks of different levels of the hierarchy is considered in order to increase the reliability, efficiency and quality of electricity supply. Particular attention is paid to asymmetric regimes in which parameters reach dangerous extreme values. The models of electric networks and their elements have been specified, taking into account the features of modern equipment and circuits. New methods of analysis have been developed for the sources of distortions in electrical networks. The means for normalization of abnormal regimes have been proposed. The peculiarities of the work of means of emergency automation with the presence of distributed generation sources in the electric network are investigated. Implementation of the developed methods and models will allow electric networks to ensure the fulfillment of constantly increasing demands for the supply quality of modern and promising consumers.
