Energy space of the Sakhalin Region

Abstract

The paper considers the specifics of the isolated energy system of the Sakhalin Region. On the basis of graph theory, the zoning of the energy space is carried out. The first zone of centralized power supply, morphologically represented by cyclic networks, is the backbone of the Sakhalin energy system and the framework of the territorial organization of society (30 % of the area). Vulnerable energy nodes and measures to strengthen them have been identified. The second zone of decentralized energy supply of Sakhalin is represented by autonomous energy systems of local scale (70 % of the area). The possibilities of centralization of power supply are minimal. The third zone of super-isolation is typical for the Kuril Islands. Their power system is represented by autonomous generation facilities, segmental network components and isolated power nodes. Due to a combination of economic and technological reasons, the development of centralized electricity supply is not advisable even in the future.
