Design of a ZETA Converter Based MPPT Controller using PSO Algorithm for Renewable Energy Source Supplying DC Load

Abstract

The creation of power from renewable energy sources like wind energy has extended as of
late because of ecological issues and the absence of ordinary energy sources in the future.
Among all the renewable assets, wind power is the most well-known assets because of its
simplicity of accessibility and its turn change into power. In this work, a basic technique for
following the maximum power (MP) attainable in the wind energy conversion system (WECS)
and nearby planetary group for direct current micro grid application is executed. A three
stage diode bridge rectifier with a dc – dc converter (ZETA converter) has been utilized
between the terminals of a wind driven induction generator and dc micro grid. The induction
generator is being worked in a self-excited mode with provocation capacitor at stator. i.e.,
dc-grid voltage is considered as a control variable to track the MP in the forthcoming WECS.
In this manner, the forthcoming calculation for maximum power point tracking (MPPT) is
separate from the machine and wind-turbine particular. This strategy has been created for
deciding the duty ratio of the dc–dc converter for the working of the forthcoming system in
MPPT area utilizing wind turbine part, the consistent state indistinguishable circuit of an
induction generator, and power value in power converters. The Circuit being simple and
basic algorithm is the advantages of the proposed WECS. The effective working of the
proposed technique for MPPT has been shown through the outcomes alongside the
simulation values.
