Abstract

This paper presents a multipurpose photovoltaic (PV) system using a lattice wave digital filter (LWDF)-based control approach. The multipurpose PV system is developed for integrating the active power to the distribution system with variable PV insolation and compensating the nonlinear loads connected at point-of-common coupling. The PV system is multifunctional; therefore, it serves various purposes. It injects the active power of solar PV array to the grid. It mitigates harmonics of loads and provides grid currents balancing. The PV system incorporates a PV array, a boost converter, a voltage-source converter (VSC), a nonlinear load, and a distribution system. The boost converter is utilized for maximum power extraction from PV array using an incremental-conductance-based maximum power point tracking technique. To control the grid-tied VSC, a LWDF-based control approach is proposed. In addition, this approach is able to produce the desired sinusoidal fundamental component of load current to estimate the grid reference currents. The aim is to implement this control as it has many properties like low-pass band sensitivity, good dynamic response, and reduction in a dc-offset noise error. The varieties of experimental results are presented to validate the control of a PV system.
