Economic Appraisal of Small Hybrid Power Supply System

Abstract

The aim of this work is to design a hybrid wind-diesel power plant for decentralized power supply system of village Khorey-Ver, Nenets autonomous okrug, Russia. Due to low population density in the north of Russia it is not economically efficient to build overhead lines and connect small settlements to the grid. That is why power supply by diesel generators is commonly used. Primary cost of produced energy is 15- 30 times higher than in central power supply systems. In order to decrease cost of energy I consider introducing RES based power supply. High wind energy potential makes it possible to use wind as a source of energy. In this master thesis, I research potential of wind energy, analyze features of implementation wind turbines in the arctic conditions. In addition, I design scheme of hybrid power plant, choose all necessary equipment and compare different wind turbines. I define exact number of wind turbines for project to be economically efficient. After introduction of wind turbines cost of energy and fuel consumption decreases. Decrease in fuel consumption leads to reduction of CO2 emissions, what makes project beneficial from economic and ecological point of view.
