The large-scale integration of wind, solar, and battery energy storage is a key feature the new power system based on renewable sources. optimization results wind turbine (WT)–photovoltaic (PV)–battery (BES) hybrid systems (HESs) can influence economic performance stability electric (EPS). However, most existing studies have overlooked effect electronic converter (PEC) efficiency capacity configuration optimization, leading to significant difference between theoretical optimal actual results. This paper introduces an accurate model applicable different types PECs, establishes enhanced mathematical along with constraint conditions for WT–PV–BES–grid–load systems, precise models. In two typical application scenarios, configurations WT–PV–BES are optimized cost as objective function. among ignoring PEC loss, using fixed models, models compared. show that in DC system, total approximately 96.63%, increases by CNY 49,420, about 8.56%, compared 100% efficiency. AC 97.64%, 4517, 2.02%, analysis clearly reveals lack PECs will greatly affect precision effectiveness optimization.

<abstract> <p>Integrating Green Renewable Energy Sources (GRES) as substitutes for fossil fuel-based energy sources is essential reducing harmful emissions. The GRES are intermittent and their integration into the conventional IEEE 30 bus configuration increases complexity nonlinearity of system. Grey Wolf optimizer (GWO) has excellent exploration capability but needs exploitation to enhance its convergence speed. Adding particle swarm optimization (PSO) with GWO leads development a novel algorithm, namely (GWPSO) algorithm capabilities. This study utilizes advantages GWPSO solve optimal power flow (OPF) problem adaptive systems, including thermal, solar photovoltaic (SP), wind turbine (WT), small hydropower (SHP) sources. Weibull, Lognormal, Gumbel probability density functions (PDFs) employed forecast output WT, SP, SHP after evaluating 8000 Monte Carlo possibilities, respectively. multi-objective green economic solution consisted 11 control variables reduce cost, losses, proposed method address OPF validated using an evaluated by comparing it PSO algorithms in terms achieving evaluation conducted within confines same test system identical constraints variables.
