Abstract

Because of the lack of transmission and distribution grid of electricity in remote and inaccessible areas due to the high cost of construction of the transmission line along with the unsuitable geographical conditions and taking into account the factors affecting sustainable energy production, renewable energy seems like a sensible solution. Therefore, in this paper, considering the solar and wind potential of Turkalan village located in East Azerbaijan Province, the combined solar-wind-diesel generator system with battery bank and independent of the grid was evaluated. Sensitivity analysis and optimal measurement of the studied system were performed by HOMER software. Sensitivity analysis was performed on the parameters of solar radiation, light reflection from the environment, and wind speed. The goal was to supply 22 kWh/d of energy with a maximum load demand of 2.5 kW. The four hybrid systems proposed by the software considering the total net present cost (NPC) were solar-generator-battery, solar-wind-generator-battery, solar-battery, and solar-wind-battery, respectively. The studies were conducted to determine which of the systems is more suitable for the area.

Highlights

  • Today, the use of renewable resources is on the agenda of many countries around the world, and an important investment process in the world is being developed in dispersed products

  • By 2016, worldwide electricity generation from fossil fuels and renewable resources is 75.5% and 24.5%, respectively, of which energy produced by countries of China, America, Brazil, Germany, and Canada is superior in this area [4,5,6]

  • The first step in designing production systems based on renewable sources is to determine renewable energy sources. e most important factor in the use of renewable energy is economic parameters; in this study, HOMER software has been used for this work and determination of economic indicators

Summary

Introduction

The use of renewable resources is on the agenda of many countries around the world, and an important investment process in the world is being developed in dispersed products. By 2016, worldwide electricity generation from fossil fuels and renewable resources is 75.5% and 24.5%, respectively, of which energy produced by countries of China, America, Brazil, Germany, and Canada is superior in this area [4,5,6]. In the design of dispersed production systems, it has combined challenges such as energy management, due to the intermittent nature of renewable resources and the diversification of energy demand [14,15,16], but the need for energy at all times of day and meeting consumer needs in mind getting system reliability due to unstable weather conditions in the area during daylight hours is used to store excess energy at times that require reduced energy consumption and the use of this energy when needed by the storage or battery [17, 18]
