Complex Research of the Annual Windpark Energy Production on the Example of the Solovetsky Archipelago

The article deals with the problem of energy supply to remote northern territories on the example of the Solovetsky Archipelago. In the Russian Arctic, there are a large number of remote settlements that are not connected to the centralized power supply system. The power supply of these areas is most often carried out by low-capacity power plants on diesel fuel. Electricity generation from diesel is very expensive because the fuel needs to be shipped over long distances. In addition, there is a risk of spills and fuel leaks during transportation. The article considers the possibility of using own energy resources of the island, in particular wind energy, as one of the solutions to these problems. Wood fuel cannot be used on the islands, as deforestation is prohibited in the archipelago.

The wind power potential of the Solovetsky Archipelago is investigated to confirm the possibility of using wind energy. Weather data on wind speed and wind direction is analyzed for the period from 2000 to 2017 for a height of 50 m. NASA Langley Research Center data are used. As a result of data analysis for 18 years, a wind rose is built. During the study, modeling of the operation of the wind park and calculation of the annual energy production are carried out with WindSim software. WindSim uses computational fluid dynamics to optimize the placement of wind power plants on shore and offshore power plants.

As a result of the study, the annual energy production of wind parks located in different parts of the island is calculated. Three wake models are tested to understand the effect of the location of the wind turbines relative to each other on the annual energy production. The loss for the selected location is found to reach 9.9%. As a result of comparing the annual energy production of the wind park in summer and winter, in winter the productivity is found to be higher than in summer, which is important when the wind park is operated in northern conditions. This case study will encourage the implementation of renewable wind energy technologies in remote islands in the Arctic region.
