New MPPT method for stand-alone photovoltaic systems operating under partially shaded conditions

摘要: Abstract A new method to track the global maximum power point (GMPP) under partially shaded conditions (PSCs), for stand-alone photovoltaic (PV) systems, is introduced. Two loads, static and dynamic, have been used evaluate effectiveness of different PSCs. Simulation results show that developed guarantees convergence GMPP PSCs provides fast in rapid variation insolation conditions. To assess performance algorithm, a comparison between two algorithms recently published has carried out. It shown outperforms other methods found literature both terms efficiency (95.80% 95% dynamic load) response time (less than 0.25 s). Negligible oscillations around MPP easy implementation are main advantages proposed method.
