Performance investigation of an advanced hybrid renewable energy system in indonesia

Abstract

The vast percentage of people of the world; particularly in the developing countries; are living mostly in the decentralized, rural and remote areas those are geographically secluded from the grid connection. Power distribution and continuous fuel transportation to produce the electrical energy for these areas pretenses a great challenge. Using renewable energy resources in off grid hybrid energy system might be a solution of this problem. Moreover, high cost of renewable energy systems has led to its slow adoption in many countries. Hence, it is vital to select an appropriate size of the system in order to reduce the cost and excess energy produced as well as to maximize the available resources. A hybrid energy system has been designed as well as simulated to support a small community considering an average load demand of 80 kWh/d with a peak load of 8.1 kW. The simulation and optimization of operations of the system have been done by HOMER software using the real time field data of solar radiation and average wind speed data of that area. The simulation ensures that the system is suitably feasible with respect to net present cost and CO2 emission reduction purpose. The result shows that NPC and CO2 emission can be reduced about 29.65% and 16 tons per year respectively compared with the conventional power plants. The NPC of the optimized system has been found about USD 160,626.00 having the per unit Cost of Energy about USD 0.431/kWh. The analyzed hybrid energy system might be applicable for other region of the world where the climate conditions are similar. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1424–1432, 2018

The renewable energy consumption-environmental degradation nexus in Top-10 polluted countries: Fresh insights from quantile-on-quantile regression approach

“…Consequently, the high level of carbon emissions is found to be coexisting with high level of renewable energy consumption. This segment of the findings contradicts the results obtained by Shezan et al (2018), who found renewable energy to be an environmental-friendly replacement for fossil fuel energy solutions.…”

Optimization and assessment of an off‐grid photovoltaic–diesel–battery hybrid sustainable energy system for remote residential applications

“…represents the comparison between the proposed HRES and conventional power plants in terms of CO 2 emissions, COE, and NPC.The results are shown inTable 6, where it can be observed that the CO 2 emission of the HRES is only 7.56% of conventional power plant. Also, the NPC per year is also only a quarter of the power plant.It can therefore be concluded that the optimized HRES is the ideal solution for power generation in a remote area of Malaysia 42. According to the analysis and simulation results, the CO 2 emissions rate per year has been found 117,245.00 kt and from other people's work as 152,347.984 which is 81,103 46,000.016 kt and less than the conventional power plants per year considering the year of 2015 forMalaysian perspective.Table 7shows the comparison of CO 2 emission and NPC per year between conventional power station and other HRES.The NPC can be varied by fuel cost, equipment cost, life time, operation, and maintenance cost.…”

Exergy and Economic Evaluation of a Hybrid Power Plant Coupling Coal with Solar Energy

“…Hybrid plants are based on the combination of two or more resources with the goal of benefitting from the advantages of each of the incorporated technologies. Hybrid plants operate with different energy sources that complement each other to obtain a desired power output [12,13]. Hybrid plants may combine conventional fossil fuel power plants with renewable energy plants or combine two or more renewable energy sources [14].…”

“…The price of coal was assumed to be 84.72 $/t [52]. 13. It was assumed that 100 employees work in the plant, with an average hourly wage equal to $20.80.…”
