Special Issue Information

Dear Colleagues,

Photovoltaic systems are an important renewable energy source that can provide green energy supply and reduce environmental damage. Effectively improving the efficiency of photovoltaic systems in using solar energy will improve their economic benefits, expand their supply and the application fields. It is of great help to the development of high civilization and the maintenance of the earth's ecology. This Special Issue will invite experts and scholars from all over the world to publish their research results on improving the use of photovoltaic systems and solar energy.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but not limited to) the following:

  1. Design of photovoltaic systems, such as ground-mounted PV systems, rooftop PV systems, building integrated PV systems, vehicle-integrated PV systems, road-integrated PV systems, urban PV systems, floating PV systems, agrivoltaic systems, fish and electricity symbiotic systems, etc.
  2. Improvement of photovoltaic system efficiency,
  3. Energy storage systems,
  4. Maintenance of photovoltaic system,
  5. Intelligent monitoring of photovoltaic system,
  6. Diagnostic and evaluation of photovoltaic system,
  7. Sunlight energy utilization.

We look forward to receiving your contributions.

In this paper, an improved firefly algorithm (FA) was proposed for application on photovoltaic module arrays (PVMAs) with partial modules under shading so that the maximum power point tracking (MPPT) could be implemented. Firstly, a new model of high voltage step-up converter was developed for executing the MPPT of the PVMA. For the energy storage inductor of the developed converter, the architecture of the coupled inductor was adopted so that the converter switch did not need to operate under an excessive duty cycle, which could increase the voltage gain and reduce the ripple of the output voltage at the same time. To prevent shading on the partial modules within the PVMA and generate more than one peak on the power-voltage (P-V) output characteristic curve, where the conventional MPPT could only track the local maximum power point (LMPP) and reduce the output power of the PVMA, the maximum power tracker, based on the improved FA, was proposed in this paper. Such a tracker could perform an automatic online adjustment on the FA iteration parameters, according to the slope of the P-V output characteristic curve, for the PVMA and, at the same time, perform at 0.8 times of the maximum power point (MPP) voltage for the module array under standard test condition (STC), serving as the initial tracking voltage for implementing the global maximum power point tracking (GMPPT). Lastly, the actual test results were applied to verify that the proposed converter indeed contained a high voltage step-up and low-ripple output voltage. The improved FA could also track GMPP faster and further improve the power-generating efficiency of the PVMA. Full article
