PublicationIntegration of a Gamma-Type Stirling Engine with LPG Cooking Stove for Micro-Scale Combined Heat and Power Generation( 2023-08-01)
;Jufrizal ;Napitupulu F.H. ;Ilmi ;Ambarita H. ;SupriatnoThe Stirling engine is one of the most versatile micro-scale prime movers for combined heat and power applications, adaptable to different levels of heat sources. This study started a unique journey that included developing, experimenting, and analyzing the Gamma-type Stirling engine. Notably, the engine design ingeniously harnesses heat from a customized cooking stove burner powered by liquefied petroleum gas. The engine fabrication resulted in a compression ratio 2.014, accommodating a volumetric capacity of 181 cc. The Stirling engine test used air as the working gas, and the initial conditions were at atmospheric pressure. Stirling engine performance was analyzed using an ideal thermodynamic cycle model and burner efficiency using the water boiling method. The modified burner attains an average temperature of 699.5°C, producing a burner power output of 5.702 kW and a thermal efficiency of 32.7% or around 1.867 kW of heat for operating the engine and cooking activities. Simultaneously, tests of the Stirling engine revealed an average air temperature difference of 146.2°C between the expansion and compression phases. The flywheel rotation speed ranges from 158 to 369 rpm. During testing, the Stirling engine obtained an average thermal efficiency of 31.08%, accompanied by an ideal power spectrum ranging from 0.3 W to 42.6 W. The highlight of this study was the maximum pressure achieved at the end of the heat absorption stage, recorded at 296.1 kPa. Importantly, these findings underscore the promising potential of micro-Combined Heat and Power systems. Integrating the gamma-type Stirling engine with the LPG stove represents novelty and paves the way for further development and advancement in sustainable energy solutions. -

;Dayang Suriani ; ;Gomesh NairThis paper discovers the use of natural dyes from Roselle flower and Blue Pea flower which act as a sensitizer in DSSC and in addition has a potential in absorbing visible light spectrum. The dyes were extracted using distilled water (DI) and ethanol (E) extract solvent in an ultrasonic cleaner for 30 minutes with a frequency of 37 Hz by using 'degas' mode at the temperature of 30°C. Absorption spectra of roselle dye and blue pea dye with different extract solvent were tested using Evolution 201 UV-Vis Spectrophotometer. It was found that Roselle dye absorbs at a range of 400 nm - 620 nm and Blue Pea absorbs at the range of wavelength 500 nm - 680 nm. Fourier-Transform Infrared (FTIR) was used to identify the functional active group in extract dye. The concept of Dye-Sensitized Solar Cell (DSSC) similar to photosynthesis process has attracted much attention since it demonstrates a great potential due to the use of low-cost materials and environmentally friendly sources of technology. -

PublicationAnalysis on the Effect of DC Current Changes on the Magnetic Field of Wireless Power Transfer( 2023-01-01)
; ;Ali M.B. ;Nugraha Y.T. ; ;Nisja I.The generation of electromagnetic radiation in a solenoid, driven by alternating current (AC) voltage, is directly influenced by the voltage and current flowing through the solenoid. Exploiting this concept, wireless power transfer (WPT) systems can be developed. These systems consist of a sending coil and a receiving coil, both equipped with solenoids. The sending coil is connected to a half bridge circuit to generate AC voltage, which is then transmitted to the receiver coil. In this study, the effects of various factors on the performance of the wireless power transfer system were investigated, with a particular focus on the impact of DC voltage and input DC current. To examine these effects, an experimental setup was employed where the transmitter and receiver coils were powered by a DC voltage source. By varying the voltage and current parameters, the study aimed to analyze their influence on the wireless power transfer process. The simulation results show that 100 V and 150 V of DC current will produce 36.54 A and 54.8 A of input DC current respectively with constant resistor 7.54×10-2 Ω. The result shows that the input DC current is directly proportional with the magnetic field, AC current at sending and receiving coil, voltage at sending and receiving coil and AC power at receiving coil. Increasing the input DC current will increase the magnetic field, AC current at sending coil and receiver coil, voltage at transmitter coil and receiving coil and AC power at receiving coil and vice versa. -

PublicationSimulation of magnetic field density in solenoid generated by current of photovoltaic module based on solar irradiance and temperature( 2017-10-01)
;Butar-Butar A.H. ;Leong J.H. ; ; ;Mahrizal MasriHermansyah AlamNormally, the magnetic field density in a solenoid is generated by a constant DC current source. A photovoltaic (PV) module is also a DC current source. The output current of PV module depends on the solar irradiance and temperature. The PV module generates a higher current on the constant temperature and higher solar irradiance. Inversely, it generates a lower current on the constant temperature and lower solar irradiance. Thus, it is important to study the output current of PV module related to the magnetic field in a solenoid. The daily data of solar irradiance and temperature are recorded by Vantage Weather Station Pro2 in Universiti Malaysia Perlis (UniMAP) throughout the year 2015. The performance of PV module (maximum peak point current) is simulated using PSpice software. The daily maximum peak point current of PV module is applied into a formulation of magnetic field density to obtain the daily maximum magnetic field density generated in a solenoid. The result shows that the higher maximum peak point current generated by PV module will produce the higher magnetic field density in a solenoid. -
PublicationPerformance Analysis of Transformerless Photovoltaic Three-Phase Inverter Using Sinusoidal Pulse Width Modulation (SPWM) Method( 2023-01-01)
; ;Foze N.A.E.M.Nugraha Y.T.This paper focuses on the simulation and analysis of transformerless photovoltaic three-phase inverter using the sinusoidal pulse width modulation (SPWM) method. The photovoltaic (PV) inverter typically applies a transformerless circuit configuration due to its high performance. The low output of inverter may cause the distortion in the output waveform and inverter will shut down. To prevent this problem from occurring, several proposals were use that are the three- phase power supply of photovoltaics in series connection to ensure the high output voltage for inverter. Next, the MOSFET operate at high frequencies, it may also be used for speedy switching applications with low turn-off losses. Lastly, using the SPWM method to reproduce a sine wave by producing one or more square pulses of voltage per half cycle and keep high performance in an inverter to avoid the distortion on output waveform. As a result, the inverter system is high efficiency, long life and fast response to load change. While for the output waveform is in the sine wave so the total harmonic distortion for current and voltage are low compared to square wave. -
PublicationThe Development of Hybrid Cooling Photovoltaic Panel by using Active and Passive Cooling System( 2024-05-01)
;Yusoff M.I. ;Jun S.Y. ;Mat M.H. ; ;Zhe L.W. ;Ibrahim S.Wahab N.H.A.Photovoltaic (PV) panel are crucial in the conversion of solar irradiance into electrical energy. However, the efficiency of PV panel is indirectly influenced by the surface temperature of the panels. According to typical PV module standards, the effect of panel temperature on efficiency is-0.47 %/°C, which indicates that a rise of 1°C reduces the PV panel's efficiency by 0.47 %. The efficiency of the PV panel achieves its maximum value when the panel temperature reaches 25 ℃, which is the standard test condition (STC). Moreover, a high working temperature can also reduce the lifetime of the PV panel. Based on the limitations that have been highlighted above, this project aims to design and develop a hybrid cooling PV panel by using active and passive cooling system with Arduino UNO R3. In this project, 100 W monocrystalline photovoltaic panel has been selected to analyze the result before and after installation of hybrid cooling system. Active cooling system is a water sprinkler system which is applied in front of the PV panel. Meanwhile, the passive cooling system is a combination of hydrogel beads and the heat-sink cooling system which will be installed behind the PV panel. In result, the average power output of PV panel without cooling was 30.59 W while the average power output of PV panel with hybrid cooling was 34.66 W. Moreover, the average power increased due to cooling was 13.31 %. In a nutshell, the proposed project has the ability to develop a hybrid cooling system to improve the performance and efficiency of the PV panel in order to increase the power output of the panel. -
PublicationControl of a multi-functional grid-connected solar PV system using instantaneous reactive power (PQ) theory for current harmonic alleviations( 2020-01-07)
; ; ; ;Azahid W.N.A. ; ; ;Abdullah A.M.In recent years, the advance usages of non-linear loads have led to the serious power quality problem in the distribution system. Non-linear load will inject the current harmonics and cause power quality problem at Point of Common Coupling (PCC). This problem can be improved by using power filter. Power filter can be divided into passive power filter and active power filter. Passive filter is an appropriate solution to solve power quality problem in term of harmonic mitigation due to a simple circuit, low cost and less energy requirement. However, active power filter (APF) is more suitable due to better performance to solve power quality problem for current harmonics issue. This paper focuses in designing the application of a multi-functional grid-connected solar PV system integrated with DSTATCOM by using Instantaneous Reactive Power (PQ) theory controller to mitigate the current harmonics injected by non-linear load at the distribution system. MATLAB/SIMULINK software is used to simulate the performance of the multi-functional GCPV based SAPF according to IEEE Standard 519:2014 which THD of the line current at the Pont of Common Coupling (PCC) should be less than 8%. -
