This study focused on feasibility analysis of hybrid electrification system for an aqua-tourism resort located remotely from the grid connection in Terengganu. There were four standalone systems used in this study: diesel/PV/biomass/battery, diesel/PV/battery, biomass/diesel/battery, and diesel only. The design and analysis of these systems were done using Hybrid Optimization of Multiple Energy Resources (HOMER) software. The results showed that the diesel/PV/battery system was the optimum solution in terms of net present cost (NPC) and cost of energy (COE). This system comprises 20 % of PV penetration with NPC and COE of USD 57,823 (RM 241, 729.90) and 0.428 USD/kWh (1.79 RM/kWh), respectively. Meanwhile, the diesel/PV/biomass/battery system with NPC of USD 65,388 (RM 273, 355.49) and COE of 0.484 USD/kWh (2.02 RM/kWh) was found to be the best among all systems in terms of greenhouse emissions. This system was able to reduce almost 70 % of carbon dioxide if compared with diesel onl...
A large number of populations of the world live in rural or remote areas those are geographically isolated. Power supply and uninterrupted fuel transportation to produce electrical power for these remote areas poses a great challenge. Using renewable energy in hybrid energy system might be a pathway to solve this problem. Malaysia is a large hilly land with the gift of renewable energy resources. There is a good chance to utilize these renewable resources to produce electrical power and to limit the dependency on the fossil fuel as well as reduce the carbon emissions. In this perspective, a research is carried out to analyze the performance of a solar-wind-diesel-battery hybrid energy system for a remote area named “KLIA Sepang station” in the state of Selangor, Malaysia. In this study, a 56 kW hybrid energy system has been proposed that is capable to support more than 50 households and 6 shops in that area. Real time field data of solar radiation and wind speed is used for the simulation and optimization of operations using “Homer” renewable energy software. The proposed system can reduce CO2 emission by about 16 tons per year compared to diesel generator only. In the same time the Cost of energy (COE) of the optimized system is USD 5.126 /kWh.The proposed hybrid energy system might be applicable for other parts of the world where the climate conditions are similar.

A large number of populations of the world; especially in developing countries; are living in rural or remote areas those are geographically isolated from the grid connection. Power supply and uninterrupted fuel transportation to produce electrical power for these areas poses a great challenge. Using renewable energy in off grid hybrid energy system might be a pathway to solve this problem. Malaysia is a hilly land with the gift of renewable energy resources. There is a possibility to utilize these renewable resources to produce electrical power and to limit the dependency on the fossil fuel. In this perspective, a research is carried out to analyze the performance of an off-grid PV (photovoltaic)-wind-diesel-battery hybrid energy system for a remote area named "KLIA Sepang Station" located in the state of Selangor, Malaysia. The system is designed as well as simulated to support a small community considering an average load demand of 33 kWh/day with a peak load of 3.9 kW. The simulation and optimization of operations of the system have been done by HOMER (Hybrid Optimization Model for Electric Renewable) software using the real time field data of solar radiation and wind speed of that area. The simulation ensures that the system is suitably feasible with respect to net present cost (NPC) and CO 2 emission reduction purpose. The result shows that NPC and CO 2 emission can be reduced about 29.65% and 16 tons per year respectively compared to the conventional power plants. The NPC of the optimized system has been found about USD 288,194.00 having the per unit Cost of Energy (COE) about USD 1.877/kWh. The analyzed hybrid energy system might be applicable for other region of the world where the climate conditions are similar.
Development of PV-Wind hybrid system installation in off grid remote islands
On the remote islet of Pserimos, which is located on the southern Greek Aegean sea a hybrid system is planned to be installed targeting to cover a share of the electricity needs of two neighbor islands, Cos and Calymnos. The transfer of the produced electricity will be achieved with the use of submarine cables, which will be linked with Cos and Calymnos common local grid, since both islands are already cabled with each other. The hybrid system will be consisted of Photovoltaic units and wind turbines, targeting towards to the substitution of the existed fossil fueled power plants with green renewable energy. The aim of this Master Thesis is to perform a data analysis based on the wind and irradiation conditions that prevail on Pserimos, targeting to the prediction of the electricity production that will be gained from hybrid’s system installation. Moreover, a geographical research of the islet was performed revealing the most favorable surface positions for the units placement, that will lead to increased electricity output. Furthermore, a monthly comparison between the electricity demand of Cos and Calymnos and the produced electricity obtained from Pserimos was investigated, in order to estimate the system’s supplied covering share. The study revealed that the expected annual energy yield obtained from the hybrid system will be around 92.18GWh, an amount able to cover the 27.85% of the yearly electricity islands need, which was calculated to be 348.64GWh. The electricity produced from the Photovoltaic units will reach the amount of 20.43GWh, whereas the turbines will contribute significantly more generating around 71.75GWh of electricity. Summer is considered as the most energy productive season due to increased irradiation and wind speed level, leading to an electricity output of 32.93GWh, which constitutes the 36% of the total annual electricity production.

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/kWhrandnetpresentcost(NPC)isU.S.0.895/kW hr and net present cost (NPC) is U.S. 0.895/kWhrandnetpresentcost(NPC)isU.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 CO 2 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.

During last few decades, many researchers have emphasized on the negative impacts of fossil fuel on environment and the increasing shortage of it. 1 Therefore, some serious efforts should be taken to find out feasible alternative energy resources before the complete reduction of the fossil fuels. Among the possible alternate energy sources, renewable energy draws the most attention to the current researchers of the world. 2 The renewable energy resources (RERs) have some inherent characteristics such as renewability, inexhaustibility, naturally replenished, and sometimes cost-effective. The main resources of renewable energy are solar (photovoltaic [PV] and thermal), wind, hydropower, biomass, tidal, wave and geothermal, and so on. 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
