Justification of project and operation modes of hybrid energy complexes for arctic conditions

Abstract

Currently, one of the priorities based on the “Energy strategy of Russia’s development to 2030” is the development of energy infrastructure of the Arctic and Far Eastern regions of Russia, which geographically make up about 65% of the country and located in the areas of decentralized power supply. The total installed capacity of diesel power plants (DPP) operating in the northern regions are more than 500 thousand kW with the production of about 2.5 billion kW·h, which requires the consumption of about 1 million tons of diesel fuel per year. Diesel fuel delivery to these regions carried out in the framework of the “northern” delivery. The article considered methods of hybrid systems based on renewable sources design, allowing optimize technical and economical parameters and increase the penetration of diesel fuel imported to the northern territories to provide consumers with the energy. The first method is a 3-level sequence of the wind energy resources (WER) assessment at a specific point of the energy complex location, for enhancing the reliability of which reanalysis database of satellite observation are used and most accurately describes the wind flow in the Russian northern regions. The second method is the operation modes justification of the power distribution between diesel generators at the diesel power plant. Both methods have been tested at the existing hybrid system 1000 kW (800 kW – diesel part, 200 kW – wind part) in the village Amderma (Nenets Autonomous District, Russia).
