How policies affect the cost-effectiveness of residential renewable energy in Iran: A techno-economic analysis for optimization

摘要

This study investigates the effects of different policies on the feasibility of residential photovoltaic and wind turbine investment in different cities of Iran. Results show that the increase of feed-in tariff in 2019 is satisfactory in several cities. Other proposed investment incentives are also explored. Self-consumption analysis elucidates that wind turbine installation in Bushehr can be employed as off-grid systems. Granting a loan to domestic investors can also enhance net present value by 172 and 122 million-IRRs for photovoltaic and wind systems, respectively. A hybrid optimization is also introduced to manage the available land and budget efficiently.
