Homer Energy Software Review Software For Professionals
Motivated by the lack of a comprehensive investigation dedicated to the techno-economic analysis of hybrid systems (PV–wind–diesel) for off-grid electrification in Peru, the present work is focused on determining the optimal configuration of these systems for remote Peruvian villages. Hybrid energy production from available renewable resources (e.g., wind and solar) and diesel engines is considered as an economically viable and environmentally friendly alternative for electrification in these areas. This is a very useful software for professionals who are in the energy sector.The majority of rural communities in developing countries (such as Peru) are not connected to the electrical grid. I have used HOMER for some of my design projects and as a professional engineer I am happy with the output. Pros: HOMER is a user friendly software that can be used effectively in designing renewable energy systems as well as energy optimization.
The obtained results have revealed that, for all of the investigated communities, the hybrid solar–wind–diesel system is the most economically viable scenario. The obtained configurations are then compared considering other state-of-the-art economic indices , the generation fractions, and the resulting CO 2 emissions. While taking into account the meteorological data and load characteristics of the communities along with the diesel fuel’s price and the cost of components, HOMER software is utilized to determine the optimal sizing of the system considering different scenarios. Seven different configurations including single component systems (solar, wind, and diesel) and hybrid ones are considered.
A hybrid renewable energy system incorporates two or more electricity generation options based on renewable energy or fossil fuel unit. Review of the state-of-the-art of researches, which use HOMER for optimal.Downloadable (with restrictions) Hybrid energy systems are being utilized for supplying electrical energy in urban, rural and remote areas to overcome the intermittence of solar and wind resources. Graphic abstractModel for Electric Renewables (HOMER) software that was developed by National. The optimal configurations that are obtained and presented in the present paper can be utilized as guideline for designing electrification systems (with a minimized cost) for the considered communities and other villages with similar characteristics (population and climatic conditions). Moreover, for the case of Campo serio, the resulting CO 2 emission of the obtained optimal system is determined to be 6.1% of that of a diesel-only unit, while the latter ratio is determined to be 2.7% for El potrero and 9.9% for that of Silicucho. Furthermore, employing the optimal configurations a renewable fraction (with respect to the total generation) of 94% is obtained for Campo serio and Silicucho, while the achieved renewable fraction for El potrero is 97%.
2015), remarkable attention has been directed toward green renewable technologies for catering growing energy demand (Mamaghani et al. Due to the ever-increasing price of petroleum derivatives on a global scale and concerns regarding the emission of greenhouse gases (GHG) (Najafi et al. Energy production from available and sustainable sources such as wind and sun has been considered as a viable and environmentally friendly alternative (Mamaghani et al. The vast majority of rustic communities in developing countries like Peru are not entirely connected to electrical grid due to geographical obstacles and small population, which make the required investments for grid extension unjustifiable. Description Reviews (0).Power access is at the forefront of governments’ preoccupations, particularly in nations in which electricity is essential for certain basic activities such as lighting, refrigeration and running of household appliances (Kanase-Patil et al. The HOMER Pro microgrid software by HOMER Energy is the global standard for optimizing microgrid design in all sectors.
To provide a stable supply of electrical power, the application of power storage systems such as batteries (Fragaki and Markvart 2008) or combining RES with non-renewable technologies such as diesel, natural gas or biomass driven generators (Montuori et al. Such nature is due to the variations in the atmospheric conditions which can result in substantial fluctuations in power generation seasonally or even daily (Bekele and Boneya 2012). The most important issue with the electricity generation by RES is the lack of stability which stems from their intermittent nature. Electricity generation in Peru through hydro, wind, solar, geothermal, biomass, tidal power or other RES is subjected to an annual maximum 20% depreciation regime for income tax purposes (Irena 2014).Despite the aforementioned upsides of RES, there are a number of technical difficulties which must be resolved to make renewable energy systems reliable and self-sufficient. In this regard, many governments have already started to finance renewable technologies by means of direct grants, loans and tax incentives (Liu et al.
For some configurations of RES projects including the wind turbine-based units, the cost of energy (COE) and net present cost (NPC) can be notably decreased by expanding the capacity of the installed power system and addressing a higher electrical load (Diab et al. Nevertheless, with respect to stand-alone diesel generators, hybrid systems require less fossil fuel (Kalantar and Mousavi 2010) (i.e., reducing operational cost), reduce carbon footprints (Bentouba and Bourouis 2016), while enhancing quality of service (Valente and De almeida 1998). Another shortcoming of RES is the significantly higher capital cost of such systems, compared to the conventional diesel generators. Hybrid energy systems, which usually comprise of at least two power sources, have been utilized to reach higher electrical efficiency and more uniform power supply.
2010), wind–diesel–battery, and wind–fuel cell systems (Khan and Iqbal 2005). Many studies have been dedicated to performance evaluation and feasibility analysis of hybrid systems such as PV–wind units (Arribas et al. This stems from the fact that naturally reliance on a single RES necessitates over-sizing the system to be able to cater the demand considering the variations in solar irradiation/wind speed throughout the day or seasonally. ( 2015) instead used HOMER to find the optimal sizing of solar photovoltaic generation to enhance the voltage profile of a rural feeder (3.06 MW peak load) in Mysuru, India.It is generally accepted that answering the electrical demand by hybrid systems (i.e., more than one RES or non-RES) is more logical than only depending on RES.
PV–wind–diesel–battery hybrid system was observed to be the most practical option (Bekele and Palm 2010) to supply a community model living in an Ethiopian remote area. In a study comparing PV–diesel and PV–battery systems, it was concluded that the former is by far more cost-effective for loads higher than 13 kWh/day while the latter is more economical for 3–13 kWh/day range (Lilienthal 2015). In a similar study conducted for the case study of Ireland, it was found that, owing to the climatic characteristics of the area, wind is the dominant component of the majority of optimal hybrid power systems (Goodbody 2013).
