North Island Grid Backbone Power Flow Study

Developed a simplified transmission network model inspired by New Zealand's North Island grid using Python and pandapower. Performed AC power flow studies to assess bus voltage profiles, transmission line loading, transformer loading, shunt capacitor impact, and EV-driven load growth scenarios.

Identified potential low-voltage areas and overloaded network elements under increased demand conditions. Compared basic mitigation options including reactive power support, transformer tap adjustment, demand management, and network reinforcement.

Power System Short-Circuit Analysis

Modelled generator bus systems and radial power networks in DIgSILENT PowerFactory. Simulated three-phase, single-line-to-ground, line-to-line, and double-line-to-ground fault scenarios to analyse short-circuit current levels under different fault conditions.

Compared fault current results against protection equipment capacity and safety margins. Strengthened practical understanding of fault current interpretation, short-circuit behaviour, and protection capacity assessment.

Wirelessly Powered RC Car Race – Dynamic IPT Receiver Design

Designed a receiver-side wireless power transfer system for an RC car originally powered by a 9.7 V NiCad battery pack, with the objective of replacing the onboard battery using a dynamic IPT power supply.

Analysed the receiver power-conversion chain, including the pickup coil, compensation and pickup regulator stage, and DC-DC buck converter required to deliver a regulated supply to the vehicle.

Worked within defined engineering constraints, including a 38.4 kHz IPT track frequency, receiver-coil inductance requirements, voltage-ripple limits, output-voltage regulation, and buck converter switching limits.

Translated project specifications into a practical converter-level design workflow, strengthening understanding of IPT-based EV charging, power electronics control, and hardware-oriented design trade-offs.

Renewable Energy and Storage Capacity Modelling

Built an Excel-based renewable energy and storage capacity model combining hydro generation, solar PV output, hourly demand, battery storage, and hydrogen storage assumptions. Analysed the relationship between installed PV capacity and required storage capacity under different scenarios.

Compared battery and hydrogen storage from a system planning perspective. Assessed trade-offs between renewable generation variability, storage sizing, and electricity supply reliability.
