WIND-DIESEL POWER SYSTEMS FOR STANDALONE ENERGY SUPPLY OF RUSSIAN NORTHERN TERRITORIES

Coastal areas of the Russian Federation (northern and far eastern territories) have a significant wind power potential. Currently, the above said areas have decentralized energy supply and, therefore, local diesel power stations (nonintegrated mill) provide electricity to them. The total installed power of diesel power stations (DPS) operating in northern regions is over 3 million kW, these DPS produce about 15 billion kWh., in that case power generation demands 5-6 million tons diesel fuel consumption annually. Diesel power stations generating costs 25-150 rubles per kWh. In the short term, the infrastructure development of Northern Sea Route ports are to be in inaugurated of the top priority nowadays. Therefore, establishing reliable and efficient power systems, which take an advantage of local renewable energy sources, mainly wind energy, and provide fuel saving with hardware adaptation for operating in cold climates maximizing energy and economic effects, is actual. During the last two years the regional authorities have shown a great interest in the construction of wind-diesel power systems as the best way to minimize the diesel fuel consumption. The paper includes results from two case studies of wind-diesel power systems (WDPS) in Russia, which should be operated in Arctic climate. Both systems are located within the polar circle with winter temperatures at least -50°C. Thus, the task to find small and medium sized wind turbine working under harsh climate cold and ice conditions was challenging. The research is focused on the detailed analysis of the wind-diesel power station (WDPS) concepts with different penetration levels and feasibility calculations. According to the results of the feasibility studies, medium penetration level scheme was proposed for WDPS in Amderma village and 250 kW wind power capacity, which provides savings of 35% of diesel fuel and payback period of 7.3 years.
