Coordinated Power Management and Control of Standalone PV-Hybrid System With Modified IWO-Based MPPT

To augment the photovoltaic (PV) power generation conversion, a maximum point tracking (MPPT) technique plays very significant role. This article introduces hybrid MPPT algorithm integrating modified invasive weed optimization (MIWO) and perturb observe (P&O) under rapid weather change partial shading scenarios for efficient extraction of from standalone PV-based system. MIWO handles initial stages followed by application P&O at final in view acquiring global peak maximal PV power. The studied microgrid comprises system, battery, electrolyzer, fuel cell, load. A coordinated dc-voltage regulation management strategy between each subsystem is implemented to save battery undesirable charging/discharging operation. Additionally, with monitoring dc voltage, dc/dc converter associated link as an circuit without requirement extra dedicated circuit. Takagi-Sugeno (TS) fuzzy controller adopted suppressing/mitigating voltage oscillations during variations solar irradiance/temperature demand. results clearly exhibit superior performance proposed methodology compared some existing techniques.
