Techno-economic Viability and Energy Conversion Analysis of RHES with Less Weight/Area

Abstract

This article proposes a new strategy to find the optimal location, configuration and size of the Renewable (wind-photovoltaic-diesel-battery) Hybrid Energy Systems (RHES (off-grid)). This study has two steps: first, the proposaltoa strategybased on a weather change to find the optimal location in Iraq using Hybrid Optimization Model for Electric-Renewables (HOMER) software. Second, the study will examine the influence of the techno-economic viability from side less weight and area on the optimal configuration/size of the RHES, which gives the maximum output power. A period of one-year for meteorological data for both solar radiation and wind speed has used. Finally, simulation results indicated that the optimal location for this RHES is the AL Harithah location. The analysis has shown that RHES can supply 89% of the load demands by renewable-energy. It is also successful in reducing the area required for installation of the RHES about 28%.

Land-Use Requirements of Solar and Wind Power

“…23 publications cover Asian countries 12,14,28,31,39,58,59,[77][78][79][80][81][82][83][84][85][86][87][88][89][90][91][92] . Comparably to Europe, solar PV LURs are available for a broader range of countries than those for CSP and onshore wind power.…”

“…Comparably to Europe, solar PV LURs are available for a broader range of countries than those for CSP and onshore wind power. LURs for solar PV technology are available for 14 countries with India being the most frequent 12,14,28,58,59,78,80,84,[88][89][90][91][92] . Wind power LURs are found for five countries in 4 publications 39,78,84,86 .…”

“…LURs for solar PV technology are available for 14 countries with India being the most frequent 12,14,28,58,59,78,80,84,[88][89][90][91][92] . Wind power LURs are found for five countries in 4 publications 39,78,84,86 . There are eight publications on CSP LURs that cover seven countries, with a main focus on China and India 31,77,79,[81][82][83]85,87 .…”

“…In the following discussion, we will explore key terms based on our systematic literature review and discuss crucial parameters that must be understood to interpret the associated LUR estimates correctly. We encountered 22 different terms for LURs across 55 publications 11,12,16,23,25,26,[28][29][30][32][33][34][35][36][38][39][40][41][41][42][43][44]46,49,50,[59][60][61][63][64][65][65][66][67][68]71,72,74,79,82,84,85,89,91,92,[96][97][98][102][103]…”

“…Such variety cannot be explained solely by actual differences between the definitions of LURs, i.e., different terms clearly point to the same LUR definition. As shown in figure 3a), the most frequently used terms are power density 18,[34][35][36]38,44,46,64,65,65,109,110 , capacity density 16,18,26,34,35,42,60,61,67,97,105 , and area requirements 40,71,79,84,102,106,107 . In the category others, we compiled terms reported only once -this was the case for 18% of publications.…”
