Performance Prediction of Building Integrated Photovoltaic System Using Hybrid Deep Learning Algorithm Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-22 Manivannan Ragupathi, Rengaraj Ramasubbu
In a grid-connected photovoltaic system, forecasting is a necessary and critical step. Solar Power is very nonlinear; this article develops and analyses building integrated photovoltaic (BIPV) forecasting algorithms for different timeframes, such as an hour, a day, and a week ahead, to manage grid operation effectively. However, a model built for a certain time scale may improve performance at that

Modeling and Simulation of Solid Oxide Fuel Cell Integrated with Anaerobic Digester, Thermal Storage Unit and Solar Collector: A Net Zero Emission System Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-21 Muhammad Nihal Naseer, Khurram Kamal, Muhammad Abid, Asif Iqbal, Hamdullah Khan, Ch. Muhammad Zubair, Sagar Kumar, Tahir Abdul Hussain Ratlamwala, Malik Muhammad Nauman
Energy production from clean and green sources is one of the eminent challenges to mankind. Overall, all industrial sectors contribute to CO2 emission, but the energy production sector is a major contributor. In recent years, CO2 emissions from the energy sector have increased by 1.7%. Therefore, the development of alternative energy production sources is a pivot for researchers. In this regard, the

Feature-Reduced Stability Analysis of Islanded Photovoltaic Microgrid Inverters Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-21 A. Om Prakash, R. Narmatha Banu
A smart grid environment is prone to data explosion while controlling a microgrid system. Islanded Microgrid’s stability analysis involves a large number of system state variables thus consuming more computational memory due to parallel connected inverter dynamics. Parallel inverters generate reference voltage and frequency using droop controllers, unlike grid-connected inverters where the primary

New Approach to Fast and Hyperstable State Observers for Stochastic and Complex Systems Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-15 undefined Kitmo, Ngoussandou Bello Pierre, Mohit Bajaj, Kareem M. AboRas, Ismail Hossain
This paper is concerned with the fast state observer for a class of continuous-time linear systems with unknown bounded parameters and sufficiently slowly time varying which satisfy the usual assumptions of conventional state observer for time-invariant plants. A less conservative approach based on hyperstability analysis is proposed to deal with the tracking error involved in Popov’s inequality. Sufficient

A Firefly Algorithm and Elite Ant System-Trained Elman Neural Network for MPPT Algorithm of PV Array Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-8 Yan Zhang, Ya-jun Wang, Han Li, Jia-Bao Chang, Jia-qi Yu
This article proposes a novel MPPT algorithm based on the firefly algorithm and elite ant system-trained Elman neural network (FA-EAS-ElmanNN). First, the position of fireflies is randomly initialized by the firefly algorithm (FA), meanwhile the firefly individuals with higher attractiveness degree value are selected as the optimal solution. Second, the extra pheromones are artificially released to

An Enhanced P&O MPPT Algorithm for PV Systems with Fast Dynamic and Steady-State Response under Real Irradiance and Temperature Conditions Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-8 Ambe Harrison, Eustace Mbaka Nfah, Jean de Dieu Nguimfack Ndongmo, Njimboh Henry Alombah
This paper presents an enhanced perturb and observe (P&O) method for reconciling the trade-off problem between the dynamic response and steady-state oscillations in maximum power point tracking (MPPT). The constraint of having to sacrifice either the dynamic response or the steady-state oscillations has been solved. The method uses the relationship between the open-circuit voltage and maximum power

Performance Analysis of a Relift Luo Converter-Derived Dual-Output DC to DC Converter for Microgrid Applications Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-4 R. Banupriya, R. Nagarajan
A microgrid typically maintains multiple voltage bus bars with AC or DC or both. The various subsystems participating in the microgrid are connected to the appropriate voltage bus bars. Renewable energy sources like the wind energy or the solar photovoltaic energy may also be integrated to the microgrid. A battery-based energy storage system is also usually required. In this work, a dual-output DC

Effects of Different Particle-Sized Al Powders on Sintering Properties of Aluminum Paste in Crystalline Silicon Solar Cell Int. J. Photoenergy (IF 3.2) Pub Date : 2022-11-3 Peng Zhu, Yang Lu, Xiaolei Chen
In this paper, the effects of particle size difference of aluminum (Al) powder on physical properties of Al powder and sintering properties of Al paste were investigated. For this purpose, respectively, Al powders with four mean particle sizes were used, which were obtained by two classifications using the same nitrogen atomization process. Thermal analysis results showed that the smaller the Al particle
