It has been proven that the efficient operation of energy storage systems in power supply systems with distributed renewable energy sources is possible only within the framework of the concept of "smart networks", a strategy for the use of energy storage means in power supply systems and a model of the operation of an energy storage device connected to the electric network are proposed. A method was developed and a mathematical model of three-dimensional strong electric fields and interconnected electrophysical processes in local microvolumes of cross-linked polyethylene insulation of high-voltage cables in the presence of conductive microdefects of various configurations was developed.
