The 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.

2017-10-01 , Butar-Butar A.H. , Leong J.H. , Muhammad Irwanto Misrun , Haziah Abdul Hamid , Mahrizal Masri , Hermansyah Alam

Normally, 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.

2020-01-07 , Muhammad Irwanto Misrun , Leow W.Z. , Ismail B. , Nor Hanisah Baharudin , 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.

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.

2023-01-01 , Muhammad Irwanto Misrun , 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.

2020 , M Masri , Muhammad Irwanto Misrun , H Alam , Y M Mashor

Pulse 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.

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%.

Artificial Neural Network (ANN) backpropagation for forecasting 100% renewable energy in North Sumatera

2025-03 , Rimbawati Rimbawati , Himsar Ambarita , Tulus Burhanuddin Sitorus , Muhammad Irwanto Misrun

Growing 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.
