Features of the Optimal Composition Determination of Energy Sources During Multi-Criterial Search in the Russian Arctic Conditions

The Russian Arctic territories energy costs are huge and need to be optimized. Their energy supplies may be provided by hybrid complexes based on renewable energy sources. The issue of determining the optimal composition of autonomous hybrid complexes is a topical and important engineering task. This article presents the results of a single-purpose composition optimization of the hybrid complex that consist of wind-solar and diesel power plants, according to the minimum cost of electricity (COE) criterium for a small settlement in the Arctic. An estimation of the additional criterion impact for the total investment cost (TIC) limitation on a result is given. It is shown that the solar and wind power proportion ratios is not constant when TIC changes and it changes to the exclusion of one of the renewable energy sources from the complex.
