This study’s goal is to assess economic and ecological performances of a set of seven different arrangements dealing with generation of energy from wind, solar and diesel assets for electrification of remote villages in Peru. Three small communities withdrawn from the principal power network with various climatic characteristics have been selected in order to investigate the feasibility of utilizing sustainable power sources (RES) with/without regular diesel generator to supply the electrical demand in each place. Seven different scenarios comprising stand alone and hybrid blend of solar, wind, diesel and battery were looked at among themselves utilizing HOMER software considering the most widely recognized economic performance indicators COE and total NPC beside emission rates as environmental criterion. Furthermore, sensitivity analysis have been conducted to investigate the impacts of variances of diesel and solar panels prices and wind turbines hub heights on the net present cost and levelized cost of energy. Results of the study indicate that use of hybrid systems is more economical than independent use of those sources in long run. In addition, sensitivity analyses are anticipating 1.81 to 4.19 percent expansion in the net present cost of hybrid systems involving solar, diesel and batteries in a study comprising simultaneous increase in diesel fuel price and falling price for solar energy system from 2017 to 2026. Finally given the fact that wind turbine power generation increases with the hub height, but also the cost, utilizing homer sensitivity analysis, 18m hub height was illustrated as optimum hub height in one of the case studies evaluated in this review.
L'obiettivo di questo studio è valutare le prestazioni economiche ed ecologiche di una serie di sette differenti configurazioni relativi alla generazione di energia da energia eolica, solare e diesel per l'elettrificazione di villaggi remoti in Perù. Sono state selezionate tre piccole comunità ritirate dalla rete principale di potenza con varie caratteristiche climatiche per studiare la fattibilità di utilizzare fonti di energia sostenibili (RES) con / senza generatore diesel regolare per fornire la domanda elettrica in ogni luogo. Sette diversi scenari composti da sola e ibrida miscela di solare, vento, diesel e batteria sono stati considerati tra di loro utilizzando il software HOMER considerando gli indicatori di performance economiche più ampiamente riconosciuti COE e NPC totale accanto a tassi di emissione come criterio ambientale. Inoltre, sono state condotte analisi di sensibilità per indagare gli impatti delle variazioni dei prezzo del carburante diesel e dei pannelli solari e delle altezze del mozzo delle turbine a vento sul costo attuale netto e il costo di energia indicato. I risultati dello studio indicano che l'uso di sistemi ibridi è più economico che l'uso indipendente di tali fonti a lungo termine. Inoltre, le analisi di sensibilità prevedono una espansione da 1,81 a 4,19% del costo attuale netto dei sistemi ibridi che coinvolgono solari, diesel e batterie in uno studio che comprende un aumento simultaneo del prezzo del carburante diesel e abbassamento in prezzo del sistema di energia solare dal 2017 al 2026. Il fatto che la generazione di energia della turbina a vento aumenta con l'altezza del mozzo, ma anche il costo, utilizzando l'analisi di sensibilità homer, l'altezza del mozzo di 18 m è stata illustrata come altezza ottimale dell'hub in uno degli studi di casi valutati in questa revisi

Abstract
This study’s goal is to assess economic and ecological performances of a set of seven different arrangements dealing with generation of energy from wind, solar and diesel assets for electrification of remote villages in Peru. Three small communities withdrawn from the principal power network with various climatic characteristics have been selected in order to investigate the feasibility of utilizing sustainable power sources (RES) with/without regular diesel generator to supply the electrical demand in each place. Seven different scenarios comprising stand alone and hybrid blend of solar, wind, diesel and battery were looked at among themselves utilizing HOMER software considering the most widely recognized economic performance indicators COE and total NPC beside emission rates as environmental criterion. Furthermore, sensitivity analysis have been conducted to investigate the impacts of variances of diesel and solar panels prices and wind turbines hub heights on the net present cost and levelized cost of energy. Results of the study indicate that use of hybrid systems is more economical than independent use of those sources in long run. In addition, sensitivity analyses are anticipating 1.81 to 4.19 percent expansion in the net present cost of hybrid systems involving solar, diesel and batteries in a study comprising simultaneous increase in diesel fuel price and falling price for solar energy system from 2017 to 2026. Finally given the fact that wind turbine power generation increases with the hub height, but also the cost, utilizing homer sensitivity analysis, 18m hub height was illustrated as optimum hub height in one of the case studies evaluated in this review.| File | Dimensione | Formato | |
