System modeling and optimization of decentralized power systems by using hybrid energy complexes with renewable energy for sustainable development.

In this paper, we highlight the problems related to UN SDG number 7 (providing affordable, reliable and sustainable energy) by analyzing the current infrastructure that provides uninterrupted reliable energy supply to technologically isolated and hard-to-reach territories in the Russian Federation. We explain the different components of Hybrid Energy Complexes that include various elements of renewable energy sources, we analyze the factors influencing the efficiency of these complexes and we optimize the composition of these complexes by using a mathematical simulation program that predicts various output indicators. By comparing our estimates with actual data in Ust-Kamchatsk, we are able to highlight the accuracy of our program as well as make conclusions on how its future implementation may have a positive effect on both ecological and economic factors.
