Research Objective
To model a solar PV-fed dual-active-bridge converter using MPPT and single-phase-shift control for stable DC-link formation and three-phase grid integration.
System Architecture
The system can include PV array, MPPT block, isolated DAB converter, phase-shift controller, DC-link capacitor, three-phase inverter, PLL, dq current control and grid measurement blocks.
Simulation Methodology
The PV operating point is regulated through MPPT, while the DAB phase shift controls power transfer to the DC link. Grid-side results validate active power injection, voltage regulation and current quality.
Validation Scenarios
- base-case model setup and parameter verification
- main design or control case under rated operating conditions
- parametric change to prove robustness and sensitivity
- comparison with baseline or conventional method
- result discussion for thesis, paper and project-report writing
Expected Graphs and Result Discussion
A complete result section should include the main waveforms, model outputs, field plots or comparison tables needed for engineering thesis documentation. For this project, the important graph set includes:
- PV voltage, current and MPPT power
- DAB phase shift and transferred power
- DC-link voltage response
- three-phase grid current waveform
- active/reactive power and dq current tracking
Thesis and Research Extension Ideas
The topic can be extended for journal-style novelty by adding optimization, robustness studies, comparative analysis, hardware-aware constraints or application-specific validation.
- partial shading MPPT comparison
- bidirectional storage interface
- SiC switching loss estimation
- grid-code reactive power support cases
