Maximum Power Point Tracking Using Particle Swarm Optimization with Chaos Searching Technique for Grid-Connected Photovoltaic System

This paper proposes a method of maximum power point tracking using particle swarm optimization with chaos searching technique (CSTPSO) for grid-connected photovoltaic systems. The system is composed of a boost converter and a Single-phase inverter connected to a utility grid. The maximum power point tracking control is based on proposed control a switch of a boost converter. CTPSO controllers provide attractive features such as fast response, good performance. The single phase inverter uses predictive current control which provides current with sinusoidal waveform. Therefore, the system is able to deliver energy with low harmonics and high power factor. From the simulation results, the adaptive CSTPSO controller can deliver more power than the conventional controller.
