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 enormous percentage of people in the world; particularly in the developing countries; are living mostly in decentralized, rural and remote areas, those are geographically secluded from the main grid connection. The power distribution and continuous fuel transportation to generate electricity for these areas pretenses a very big challenge. By proper utilization of renewable energy resources in off grid hybrid energy systems will be an efficient solution of this crisis. Moreover, the high cost of renewable energy systems has led to its slow adoption in many developing countries. Hence, it is very important to find an appropriate size of system in order to reduce the energy cost and excess electricity generation as well as to maximize the available resources. Therefore, a hybrid energy system has been designed and simulated to support a small community considering an average load demand of 85 kWh/d with a peak load of 8.7 kW. The simulation and optimization of the system have been performed by the HOMER software using real time field data of solar radiation, wind speed and biomass of that particular area. The simulation results confirm that the system is suitably feasible with respect to the net present cost (NPC) and CO 2 emission reduction purpose. The simulation results also confirm that the NPC and CO 2 emission can be reduced about 32.45% and 29 tons per year respectively compared to the conventional power plants. The NPC of the optimized system has been found about USD $160,626 having per unit Cost of Energy

“…This study has chosen the PV as one of the energy resource components of the proposed hybrid system suitable for off-grid residential power supply. 3,4 The grid-connected PV system can be suitable for centralized and urbanized area but the off-grid stand-alone PV system will be much more effective for remote and decentralized area. The main challenge of grid-connected PV system is to match the voltage and frequency within the range of normal grid.…”

Due to the increasing demand for electricity for the ecotourism areas like Malaysia, alternative energy sources are being required. In this research article, an investigation for the comprehensive off‐grid photovoltaic (PV)–diesel–battery hybrid alternative energy system design with an energy backup of a 5‐kW diesel generator is represented. From the simulation and optimization results, it can be observed that 38 kW hr/day load demand combined with 5‐kW peak load for 37 family units for an ecotourism areas of Malaysia can be fulfilled by establishing the proposed hybrid PV–diesel–battery energy system. It can also be observed from the optimization outcomes that the proposed hybrid renewable energy system (HRES) is the most economically feasible energy system and the levelized cost of energy (COE) is nearing U.S. $0.895/kW hr and net present cost (NPC) is U.S. $158,206, and the COE and NPC have been minimized according to the current market price. After collecting meteorological data, a complete simulation has been conducted with the other parameters to achieve an optimal solution of the PV–diesel–battery hybrid alternative energy system. The decrement of the CO2 emission can be compared to the existing results with the other conventional and HRESs. The simulation results from Hybrid Optimization Model for Electric Renewable software have been validated by using Photovoltaic System Tools (PVSYST) renewable energy platform. The analyzed energy system will be applicable where the meteorological conditions are the same.
