Optimizing Solar Energy Harvesting: A Simulation Study Of Fuzzy Logic And Enhanced Perturb & Observe MPPT Techniques For Standalone PV Systems

Abstract

Solar photovoltaic technologies provide us the ideal instrument to end our reliance on fossil fuels, which must undoubtedly be curbed. It is necessary to enhance efficiency in order to transition energy production to rely on renewable sources. Solar panels have been around since the 1950s, but they still aren't very efficient. Maximum Power Point Tracking (MPPT) devices are being used to counteract the inefficiency of solar panels by monitoring the maximum working power and voltage. Finding the most effective, stable, and efficient method among three popular techniques to MPPT is the goal of this research. In order to monitor the maximum power, the method uses perturb and observe (P&O), fuzzy logic, and enhanced P&O to change the voltage the battery needs to charge itself. The whole investigation relies on simulations run in MATLAB Simulink with the help of the Simscape module. We assume the panel is in an unmoving, light-filled condition. Being exposed to light at a steady rate with just little variations in ambient light. The primary goal was to determine which algorithm performed the best under controlled conditions using the same inputs. In terms of decreased oscillation in output power, rapid climb to maximum power, level power point tracking, and an efficiency of 96.55%, the enhanced P&O controller performed better when the power and voltage measurements were displayed. The output power of traditional P&O and fuzzy logic algorithms is more harmonic, but they were not far behind with efficiency of 93.91% and 94.39%, respectively. Photovoltaic (PV) techniques can collect water from Chattogram, Bangladesh [email protected] [2], [3]. Solar cells are the fundamental building block of the photovoltaic system. These solar cells often make use of semiconductors. In order to facilitate the construction of solar cells, the materials are heavily doped. These cells use a process known as the photoelectric effect to convert sun energy into electrical energy. Solar cells and photovoltaic cells convert light into electricity the second they come into contact with light. Similarly, photovoltaic (PV) modules allow for the rapid conversion of sunlight into power. An array of photovoltaic (PV) modules is formed when many modules are linked in series and parallel to provide an attractive voltage and current distribution. In order to get the most out of a PV module, it's best to use it at or near its maximum power setting. The amount of power generated by the solar PV modules is susceptible to a number of variables. The quantity and pace of energy storage are the most important. Maintaining the output power at the highest possible power from a PV array is how highest Power Point Tracking (MPPT) works [4]. With maximum power point tracking (MPPT), a battery bank may be charged while the PV output voltage is maintained at an optimal level for charging and current regulation. Add as much power as possible to the battery. It continues to operate regardless of cloud cover or reduced sunshine. Therefore, this MPPT may help make better use of renewable solar power.
