- The accurate sizing of the inverter, specifically power ratio (PSR) plays a vital role in maximizing energy production and economic benefits. Existing studies often overlook complex interplay between capture minimizing inverter-related costs when selecting optimal PSR. This research presents techno-economic approach to optimizing PSR for grid-connected photovoltaic (PV) systems. A simulation model is developed, incorporating real weather data inverter efficiency curves. calibrated using Pattern Search Algorithm (PSA) ensure an representation real-world behavior by achieving minimum relative difference 13.78 % (Norm-RMS) AC output. analysis explores trade-off PSR, annual yield, clipping. An 1.19 identified, balancing (up 2000W capacity) efficiency. promotes cost-effective selection wider PV adoption.

Abstract This study looks into how to make proton exchange membrane (PEM) fuel cells work more efficiently in environments that change over time using new Maximum Power Point Tracking (MPPT) methods. We evaluate the efficacy of Flying Squirrel Search Optimization (FSSO) and Cuckoo (CS) algorithms adapting varying conditions, including fluctuations pressure temperature. Through meticulous simulations analyses, explores collaborative integration these techniques with boost converters enhance reliability productivity. It was found FSSO consistently works better than CS, achieving an average increase 12.5% power extraction from PEM a variety operational situations. Additionally, exhibits superior adaptability convergence speed, maximum point (MPP) 25% faster CS. These findings underscore substantial potential as robust efficient MPPT method for optimizing cell systems. The contributes quantitative insights advancing green energy solutions suggests avenues future exploration hybrid optimization
