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. -

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%. -
PublicationPhotovoltaic powered DC-DC boost converter based on PID controller for battery charging system( 2020-01-07)
; ;Leow W.Z. ;Ismail B. ; ;Juliangga R. ;Alam H.Masri M.The input voltage of battery charging system is always above the battery nominal voltage and it should be remained constant. But it depends on the type of input voltage sources. A battery charged directly by photovoltaic (PV) module as the input voltage source can cause the output voltage of PV module or the input voltage of battery charging system can fluctuate, because the output voltage of PV module depends on the solar irradiance. This problem can be solved by installing DC-DC boost converter between the PV module and battery. This paper presents a DC-DC boost converter based on PID controller for battery charging system. It is designed for the input voltage of 12V and output voltage of 14.7V system because it is applied to charge a 12 V, 7 Ah lead acid battery. Based on the simulation result of battery charging system shows that the output voltage of DC-DC boost converter can be remain around 14.7 V. It is due to the PID controller can damp the voltage oscillation and remain its steady state voltage. The time needed by the DC-DC boost converter to charge the battery in the fully charging condition is 1 hour: 3 minutes: 37seconds. -
PublicationSimulation of multiple pulse width modulation (MPWM) transformerless photovoltaic inverter (TPVI) systemPulse width modulation technique is always applied in the design of inverter. The output voltage waveform of inverter is not relative pure sinusoidal, especially if it is applied linear pulse width modulation. A non-pure sinusoidal voltage waveform can affect the life time of inverter and also the alternating current (AC) loads. The inverter always also uses a transformer that can increase the losses and reduce the efficiency. A technique of multiple pulse width modulation (MPWM) is suitable to be applied in the transformerless photovoltaic inverter (TPVI) system. It can generate pure sinusoidal voltage waveform and increase the performance of inverter. This paper presents a simulation of MPWM TPVI system using SIMULINK MATLAB. It consists of pulse driver circuit to drive four MOSFETs in the full bridge inverter circuit with the output voltage waveform still multiple pulse wave and it is converted to be pure sinusoidal voltage waveform by applying a LC filter circuit.

PublicationArtificial Neural Network (ANN) backpropagation for forecasting 100% renewable energy in North Sumatera(Kauno Technologijos Universitetas, 2025-03)
;Rimbawati Rimbawati ;Himsar Ambarita ;Tulus Burhanuddin SitorusGrowing environmental awareness and the increasing need to reduce reliance on fossil fuels have driven the development of renewable energy (RE) technologies, such as micro-hydro, photovoltaics, biomass, geothermal, and biogas. However, the utilisation of RE in North Sumatera remains limited compared with fossil fuels, highlighting the need for optimisation strategies to accelerate the transition towards 100% RE. This study develops a predictive model using the artificial neural network (ANN) backpropagation algorithm to maximise RE contributions, minimise dependence on fossil fuels, and forecast the timeline for a full transition to RE. Data from Perusahaan Listrik Negara (North Sumatera), Independent Power Producers (IPP), and palm oil mills were used to model a hybrid generation system incorporating micro-hydro, hydropower, geothermal, biomass, biogas, and solar energy. Simulations were carried out using the firefly algorithm (FA) and particle swarm optimisation (PSO), with optimisation assessed through the renewable energy contribution ratio (RECR). The results indicate that FA outperforms PSO in meeting RE targets, with an average RECR of −51.514 for FA compared with −911.054 for PSO. Predictions using ANN backpropagation suggest that the transition to 100% RE could be realised by 2064 (FA) and 2065 (PSO). This research offers valuable insights for accelerating the transition to sustainable energy, enhancing energy resilience, and reducing environmental impacts.
