The paper deals with the intelligent network modes based on the Smart Grid concept with the function of two-way energy flow, both from the power system and from its sources of distributed generation. The expanded interpretation and the meaning of the intellectual network concept - Smart Grid - is proposed, based on its abbreviation, which determines the system criteria for its purpose. A new concept is introduced and new definition - Holonic Approach - Smart Grid concept. A new term has been introduced: - "Generating Consumer-Holon" (GC-Holon), which means the ability of an electric consumer to independently generate energy using renewable sources, store it, exchange energy with other similar GC-Holon and the main generating system. In connection with this, the concept of a generating consumer has been introduced. To construct an intelligent network, a holonic structure based on a set of holons (subsystems) is used. The holonic structure assumes subsystems of different nature, located at different levels of aggregation, interconnected in order to form a hierarchy of selfregulating holons, called Holarchy. According to A. Koestler, holons are simultaneously, both whole and partial. They are basically autonomous, which allows them to ensure their existence independently. The two-way energy flow for the holonic structure assumes the possibility of generation and storage of energy due to the internal structure of the electric consumer. The infrastructure of an intelligent network and its applications are considered. A mathematical model of bilateral electric power consumption by a generating consumer is proposed, taking into account tariffs and pricing. This allows you to flexibly regulate energy flow and align the load schedule, minimizing financial expenses for consumed energy.
