Using an adaptive quadrature-complex variable filter based on a fractional-order PID (FOPID) controller, this
study aims to improve power quality. Using a FOPID-based control approach, this paper investigates an
adaptive quadrature-complex variable filter (AQ-CVF). An effective way to minimize and enhance power
quality for different nonlinear loads connected at the Point of Common Interconnection (PCI) is to use gridinterfaced
solar photovoltaic (PV) and battery energy storage (BES) systems. An key function of the
bidirectional converter (DBC) is to tell the BES to keep critical loads powered even when the RES's output is
insufficient. The study also highlights the potential operational issues that may develop as a result of changes in
the input and output power of the HSWGIS, which stands for hybrid solar PV-wind -BES linked grid
internetwork. In order to evaluate the control mechanism's suitability for the PV-BES grid interfaced system, we
provide several static and dynamic modes of operation. The Perturb and Observe (P&O) method and a boost
converter (BC) collaborate to maximize the use of renewable energy sources. Examining HSWGIS's
performance allows us to validate the efficacy of control approaches in different operational contexts.
