Prospects for the Implementation of Wind Power Plants into the Heat Supply Systems of Consumers in the Western Sector of the Arctic

The problem of heat supply to remote dispersed consumers of the Arctic and the possibility of such a local renewable energy source as wind to be involved in are considered. The wind potency distribution over the western sector of the Russian Arctic is shown. Areas with enhanced wind potency are identified, which are the most promising ones for heating needs. Wind energy cadastre principal characteristics of the region are studied (average long-term wind speeds, seasonal distribution in average monthly speeds, wind speed frequency, etc.). The Arctic coastal regions are established to have the greatest wind potency. In these areas there is a winter peak of wind speeds, which coincides with the heat and electrical power peak demand. This is the main prerequisite for the successful joint operation of current boiler rooms with wind power plants (WPPs), which are able to provide a significant part of the heating load. It is shown that the use of wind energy will save (displace) a significant amount of expensive imported fuel and significantly reduce the working cost of heat generated. Wind influence on the reduced average annual outdoor temperature (subject to wind) is studied. It is shown at what extent the wind changes the calculated temperature of the coldest five-day period, which is the basis for determining the maximum boiler output. The consumer heating-load curve and its provision by WPPs possible participation and boiler rooms are considered. As a result, it is concluded that up to 60-80% of all energy input can be provided in the Arctic regions with increased wind potency by WPPs introduced into heat supply systems.
