Grid Connected PV System with MPPT Scheme Using Particle Swarm Optimization Technique

Abstract

Electrical Energy has become one of the basic needs of an individual in this era. The requirement for energy is constantly rising day by day. The majority of electricity is presently generated by traditional thermal or hydro power plants. Renewable sources are very fashionable and popular for green energy and very widespread used nowadays. The electricity provided by photovoltaic (PV) systems is a very typical example of a clean renewable energy supply. When it comes to using PV as a renewable energy source, components like as an inverter are frequently utilized in this circumstance, and many ways have been presented to date to extract the most produced power from a PV system. This article recommends a 50 kW 3-phase grid-associated system with different topologies such as, single stage and dual stage P&O based MPPT techniques. A DC-AC converter, based on PWM for processing the energy generated by a solar array that is composed of SunPower SPR-230E-WHT-D PV modules with high power factor at any solar radiation. To improve the power quality, A control approach is presented in this article using Park's transformation (dq0 transformation) operators with for any scenario of solar radiation, a current control function in three phase grid-connected solar power generation with unity power factor is used. Harmonic components and reactive power provided by loads attached to the device can be compensated by the system and along with this a PSO based topology for MPPT to compare PSO with P&O technique and obtain best results. .
