Feasibility Study for Power Generation during Peak Hours with a Hybrid System in a Recycled Paper Mill

Abstract

The differential pricing for peak hours encourages industrial consumers to look for independent power supplies for the period from 19 to 22 hours. This paper presents a study to identify the optimal solution for a recycled paper mill that also intends to work in that period. The factory is located in Rio Grande do Sul, in southern Brazil, and considers the use of a diesel gen set, a micro hydro power plant and possibly PV modules. Two micro hydro power plants were considered in the study, an old plant to be renewed and another to be fully implemented. The software Homer was used as a tool to determine the most feasible combination of components considered in the study. The sale of surplus power to the energy system appears as a key to viability of alternatives that are not based solely on diesel generators. The optimal solution consists of a combination of diesel generators and micro hydro power plant, in one case, and only on hydroelectric power plant in another, with a significant penetration of PV modules if its cost is reduced to 12% of the current price, selling an amount of energy equal to that which is bought. The annual water availability in one of the sites requires diesel supplement, while the other, more abundant, this supplement is not necessary. 1 The city of Caxias do Sul can be located on Google Maps [4] at

Feasibility and optimal design of a hybrid power system for rural electrification for a small village

“…The rural electrification agency (REA) has classified Nigeria as one of the potential areas where off-grid hybrid renewable energy can be used effectively for rural electrification [8,9]. Off-grid rural populace deserves sustainable, reliable and cost-effective energy system to serve as an alternative to the environmentally unfriendly and expensive power supplied by the conventional energy system [11,12].…”

“…The study concluded that the hybrid system is efficient in emission reduction. A study to identify the best solution for a recycled paper mill located in Rio Grande do soul, Southern Brazil for peak hours (19-22 hours) was conducted by [11]. The method considered the cost at peak hours only, the reliability was not considered.…”

Dataset after Seven Years Simulating Hybrid Energy Systems with Homer Legacy

“…Among the other case studies, the first three of them (Silva, Cardoso & Beluco, 2012;Beluco & Ponticelli, 2014;Beluco et al, 2013) deal with the insertion of PV modules and-or other components or new fuels into previously existing diesel hybrid systems and the fourth (Benevit et al, 2016) of them studies the subtle influence of different wind energy availability profiles on the performance of a wind diesel hybrid system.…”
