This paper presents a comprehensive optimization framework for modern distribution systems, integrating system reconfiguration (DSR), soft open point (SOP) operation, photovoltaic (PV) allocation, and energy storage (ESS) management to minimize daily active power losses. The proposed approach employs novel hybrid metaheuristic algorithm, the Cheetah-Grey Wolf Optimizer (CGWO), which synergizes global exploration capabilities of Cheetah (CO) with local exploitation strengths Grey Optimization (GWO). model addresses time-varying loads, renewable generation profiles, dynamic network topology while rigorously enforcing operational constraints, including radiality, voltage limits, ESS state-of-charge dynamics, SOP capacity. Simulations on 33-bus demonstrate effectiveness across eight case studies, full DER integration (DSR + PV SOP) achieving 67.2% reduction in losses compared base configuration. By combining CO GWO, CGWO algorithm outperforms traditional techniques (such as PSO GWO) avoids premature convergence preserving computational efficiency—two major drawbacks standalone metaheuristics. Comparative analysis highlights CGWO’s superiority over algorithms, yielding lowest (997.41 kWh), balanced utilization, stable profiles. results underscore transformative potential coordinated enhancing grid efficiency reliability.

Abstract Semi‐transparent solar cells represent an exciting opportunity for sustainable energy production, thanks to the possibility of being integrated into buildings and urban environments, effectively exploiting already existing space. Perovskite (PCSs) are ideal candidates, offering high power conversion efficiencies (PCEs) combined with a tuneable band gap adjustable thickness, which allow convenient modulation average visible transmittance (AVT). However, balancing PCE AVT is challenging target. This study uncovers that depositing perovskite layer based on Formamidinium Lead Iodide (FAPbI 3 ) thin films in ambient air, rather than nitrogen‐controlled atmosphere, allows increase value up > 40% while also enhancing photovoltaic performance stability. The optoelectronic quality as‐obtained substantially enhanced, showing fewer defects superior morphology. As result, air‐deposited devices exhibit higher efficiency, which, combines enhanced AVT, results champion device light use efficiency (LUE) 4.2%, having 13.8% 30.4%. record LUE deposited air conditions pave avenue toward real‐world application semi‐transparent PSCs.
