Seamless Capable PV Power Generation System without Battery Storage for Rural Residential Load

The presented system is a three-phase three-wire (3P–3W), seamless, capable, dual-stage PV power generation without battery storage for rural residential loads to ensure continuous supply during the daytime. This effortlessly shifts from grid-connected (GC) mode standalone (SA) when grid utility unavailable. During GC mode, voltage source converter (VSC) regulated by polynomial zero-attracting least mean square (PZA-LMS) algorithm-based current control scheme. balance achieved at point of common coupling (PCC) exchanging active with grid, whereas VSC delivers reactive power. Considering low efficiency systems, an incremental conductance (InC)-based maximum tracking (MPPT) algorithm necessary extraction out array. unavailability operates in SA load delivered only via VSC. high cost (BSS), bi-directional converter, and charge circuitry incurred consumers, they were omitted system. Without BSS, InC-based MPPT executed derated extracting exactly match demand. operation, may be damaged due excess flow end or remain underpowered, leading shedding complete disconnection. A synchronous reference frame (SRF)-based scheme responsible operation performance was observed found satisfactory irradiation variation, balancing, islanding, re-synchronization grid. carry harmonics suppression PCC both modes. grid’s total distortion (THD) levels shown kept below 5% as per IEEE 519 standard mode.
