Stand-alone energy supply system with distributed photovoltaic generation

Abstract

The quality of electricity supply due to decreased voltage is becoming essential in countries with a vast territory and numerous settlements (for instance, China and Russia). This master thesis focuses on developing approaches to design a hybrid power supply for the needs of the rural settlement. I develop an algorithm for determining an optimal structure of a power supply system considering technical, economic, environmental, and local aspects. The aim of the thesis is to create a technical and financial model in order to evaluate the installation of the hybrid system and to analyze its effectiveness. In order to achieve this goal, I study the necessary generation capacity to analyze load coverage, and I also provide technical and economic analyses. One of my most important contributions is the analysis of investment and methods for reaching the maximum economic efficiency. I model the hybrid system, using the real data of the decentralized settlement in Russia's Siberia area, which are analyzed in MS Excel, Homer Energy, and MatLab. For the economic part, I analyze the market of generating equipment as well as the investment, using discounted payback period, NPV, and IRR.
