This research is a numerical study, with simulation and experimental investigation of a novel photovoltaic and biogas hybrid renewable energy system. PVSYST simulation software is used to evaluate the energy generation of photovoltaic (PV) systems installed at optimum tilt angle and interrow spacing, as well as measure the performance ratio and system losses. The results obtained from simulations show that annual energy production from designed PV system is 16 654.80 kWh year−1 and its annual specific energy production is 1556.5 kWh kWp year−1. The average annual performance ratio is about 84.3%, normalized array production is 3.23 kWh kWp day−1, normalized system losses are 0.07 kWh kWp day−1, and normalized system production is 3.16 kWh kWp day−1. With SuperPro Designer software, a model is developed for simulating anaerobic digestion for treating animal manure to produce biogas. The simulation yields 88.13% of CH4 and 6.49% of CO2. The performance of the installed experimental setup is examined for 30 d. The maximum load demand of all houses is 46.902 kWh, whereas maximum energy produced by a hybrid PV/biogas system is 61.06 kWh. The payback period for a hybrid photovoltaic/biogas system is estimated to be 4.47 years and levelized cost of energy is 0.0186 USD kWh−1. The hybrid PV/biogas system results in net CO2 mitigation of 20.45 tCO2(e).

To meet the demands of power supply for applications along the railway in treacherous terrain, this article proposes a portable photovoltaic power generation system (PVPGS) based on a foldable mechanism for applications along the railway. First, the designed system mainly consists of a foldable solar energy collector (FSEC) and an energy conduit. Dust deposited on the photovoltaic panels is reduced while the FSEC is being folded or unfolded. Moreover, the characteristics of dust particles, effects of natural dust on photovoltaic glass transmittance, and power of portable PVPGS are investigated. In addition, the mechanism on improving the power generation efficiency of PVPGS is analyzed. The results demonstrate that the designed foldable mechanism can contain the dust deposition on photovoltaic power loss within 4%. Finally, Chengdu city and Sichuan–Tibet Railway are selected for an application prospect, and the results show that the average annual power generation of one portable PVPGS can reach up to 16.7 kWh, which is enough to power sensors and other applications along the railway. Simulations, theoretical analyses, and experiments confirm the feasibility of using the proposed portable PVPGS to power applications along the railway.

Solar energy is the most techno-economically viable renewable source of energy and can be effectively converted into electrical power by Photovoltaic (PV) systems. As partial shading (PS) may reduce the harvested energy of PV systems, this paper proposes a novel tunicate swarm algorithm (TSA) based MPPT (maximum power point tracking) strategy to tackle the PS issue. More specifically, the simple and effective modeling of TSA with a search and skipping (SAS) scheme is utilized to minimize the tracking time and search area. The SAS scheme can discard the voltage range lacking global maximum power point (GMPP) and significantly reduce computation time. Consequently, power tracking, tracking time, and robustness can be greatly enhanced. The performance of the proposed TSA strategy is comprehensively analyzed against state-of-the-art techniques, including incremental conductance (InC), improved particle swarm optimization (IPSO), grey wolf optimization (GWO), and cuckoo search algorithm (CSA), through detailed case studies, which include standard array configurations, PS conditions, varying irradiance patterns, fast-changing temperature, and the field atmospheric data. TSA is further validated on a low-cost hardware setup, confirming its superior performance. The results provide insightful validation of the practicality of the proposed TSA strategy in the real-world applications.
