An Optimal Current Control Strategy For A Three-Phase Grid-Connected Photovoltaic System Using Particle Swarm Optimization, Waleed Al-Saedi, Stefan W. Lachowicz, Daryoush Habibi Jan 2011

An Optimal Current Control Strategy For A Three-Phase Grid-Connected Photovoltaic System Using Particle Swarm Optimization, Waleed Al-Saedi, Stefan W. Lachowicz, Daryoush Habibi

Research outputs 2011

A robust current control strategy for PV (photovoltaic) grid-connected systems is required for reliable use of solar energy as an abundant and clean renewable energy. This paper presents real time optimization parameters of the current control strategy for a 3-phase photovoltaic grid-connected Voltage Source Inverter (VSI) system. The proposed controller scheme is implemented based on a synchronous reference frame; the Phase-Locked Loop (PLL) is used as grid phase detector. Particle Swarm Optimization (PSO) algorithm is an intelligent searching algorithm that is used to implement the real time self-tuning method for the current control parameters. Two conventional PI controllers are used …

This paper presents an optimal power control strategy for an autonomous microgrid operation based on a real-time self-tuning method. The purpose of this work is to improve the quality of power supply where Distributed Generation (DG) units are connected to the grid. Dynamic response and harmonics distortion are the two main performance parameters which are considered in this work, particularly when the microgrid is islanded. The controller scheme is composed of an inner current control loop and an outer power control loop based on a synchronous reference frame and the conventional PI regulators. Particle Swarm Optimization (PSO) is an intelligent …
