Photovoltaic battery storage system for maximum power point tracking using hybrid firefly and perturbation and observation algorithm
Abstract
This paper presents the novel maximum power point tracking (MPPT) approach for a small 50 W photovoltaic (PV) based battery storage system using the DC-DC converter. The method of modeling of PV module is discussed. The firefly (FFY) algorithm along with the perturbation and observation (P&O) algorithm are combined together to implement MPPT of the PV battery storage system. The operating principle is discussed in detail and steady-state analysis of the proposed system is implemented through simulation. The charging profile of the battery is also studied. Furthermore, a low-cost microcontroller-based experimental setup rated at 50 W battery storage systems was built to implement a hybrid FFY-P&O algorithm. The experimental results are in line with the simulation result. It showed the fast and excellent maximum power point operation due to rapid as compared to conventional P&O method.
