Abstract

This study aimed to provide a mathematical model for the determination of optimal wind power price in the case of construction of new off-grid-connected wind power plants in different areas. The proposed model is based on nine features including construction cost, side costs (cost of replacement, maintenance, and repairs), pollution, electricity generation, profit, renewability level, green economy, rate of return on investment, and consumption. First, the inputs of the mathematical model were obtained by technical–economic feasibility evaluation of the study areas in the software Homer using the 10-year wind speed data (2006–2016). The optimal wind power prices were then determined in three different modes by solving the mathematical model with MATLAB. The modes considered in optimization were the construction of 1, 2, and 3 wind power plants in the study areas. Simulation of construction of wind power plants in each mode was conducted in the software Homer. The results showed that the optimal wind power price resulting from construction of 1, 2, and 3 are 0.159, 0.151, and 0.140 $ per kilowatt, respectively. The proposed mathematical model was found to have sufficient capability in determination of optimal wind power price.

Highlights

Recent years have witnessed a steady increase in the share of renewable energies in the world’s energy portfolio; an increase that has contributed to reduction of greenhouse gas emissions and to diversification and security of energy supplies and growth of business and employment in renewable energy industry [1, 2]
The aim of the present study was to facilitate the simultaneous optimization of renewable electricity price and construction of new isolated wind power plants in different areas of a region with the help of mathematical modeling
A mathematical model was introduced for determination of optimal wind power price according to the number and capacity of wind power plants based on nine features including construction cost, side cost, pollution, electricity generation, profit, renewability level, green economy, rate of return on investment, and consumption

Summary

Introduction

Recent years have witnessed a steady increase in the share of renewable energies in the world’s energy portfolio; an increase that has contributed to reduction of greenhouse gas emissions and to diversification and security of energy supplies and growth of business and employment in renewable energy industry [1, 2]. Despite the high potentials of a variety of renewable energies in Iran, inadequate pricing and access to relatively cheap oil and gas resources have impeded the progress of renewable energies in this country [3]. In the past 15 years, guaranteed purchase of renewable electricity has been as common support measure in many countries. This practice is relatively new in Iran and investment in this sector under current situation is not cost-effective [4,5,6]. It has been shown that pricing is one of the key factors of promotion and success of renewable energies. Renewable energy pricing is identical to fossil energy pricing except that it takes account of environmental impacts of fossil fuel [7]
