What are some Electrical Engineering Thesis ideas?

Electrical engineering is a broad field with many potential areas of research for advanced degree theses. Some common thesis topics involve circuit design, signal processing, power systems, communications, controls, electronics, electromagnetics, and more. This response will outline several detailed thesis ideas that an electrical engineering graduate student could explore.

Idea #1: Design of an Efficient Three-Phase Inverter for Solar Microgrid Applications

Renewable energy generation from solar panels is increasing rapidly around the world. Integrating variable solar power into local electrical grids presents challenges due to the fluctuating nature of sunlight. One solution is to install solar microgrids which use power inverters to convert the direct current (DC) output of solar panels into the alternating current (AC) needed by local loads. For a thesis, a student could design and build a prototype three-phase inverter specifically optimized for integration into small-scale solar microgrids serving neighborhoods or commercial buildings. The inverter design would aim to maximize efficiency over a wide range of operating conditions using advanced switching strategies and maximum power point tracking algorithms. A model-based controls design approach could be applied and hardware-in-the-loop testing performed. Results would be analyzed to demonstrate improvements in performance, reliability and cost compared to conventional single-phase inverter solutions. Upon completion, the inverter design could have applications for demonstration projects or commercialization.

Idea #2: Application of Deep Learning Techniques to Predictive Maintenance of Power Transformers

Power transformers are crucial equipment in electricity transmission and distribution systems, but unplanned outages can be very costly. One way to reduce these risks and maintenance costs is through implementation of condition monitoring and predictive analytics. For a thesis, a student could explore applying deep learning methods like convolutional neural networks to analyze datasets containing sensor measurements and test results from fleets of operational transformers. The aim would be to develop models capable of automatically recognizing early signs of deteriorating conditions and remaining useful life. This could provide utilities with timely warnings to schedule maintenance when convenient rather than waiting for outright failure. The thesis would involve collecting real transformer data, preprocessing, designing network architectures, training and validation. Successful predictive models could then be integrated into maintenance management systems and help enable more proactive “condition-based” strategies industry-wide.

Idea #3: Autonomous Multi-Robot Coordination for Inspection of Overhead High-Voltage Transmission Lines 

Traditional inspection methods for high-voltage transmission lines require specialized equipment and human workers performing dangerous tasks while suspended in the air. As an alternative, a thesis could explore using fleets of small, cooperative robots autonomously controlled from the ground to inspect transmission towers and conductors. Key challenges would include simultaneous localization and mapping of the difficult overhead environment, multi-agent coordination and communication protocols, visual inspection techniques using cameras/sensors, and strategies for navigating complex tower geometries safely. Machine learning and distributed control algorithms could feature strongly. The work would culminate in demonstration of an initial prototype robot system able to autonomously map, coordinate and share sensor data between agents to inspect sections of a decommissioned test line. if successful, the research could help pave the way for entirely new automated solutions providing utilities safer, lower-cost alternatives to manned inspections.

Idea #4: Utilizing Short-Term Forecasting and Electric Vehicle Charging Coordination to Support High Renewable Energy Penetration on Distribution Networks  

Continued integration of variable renewable generation like wind and solar is placing new technical and economic stresses on electric power distribution systems. However, electric vehicles (EVs) which can charge flexibly offer potential benefits if coordinated optimally. A thesis could focus on developing strategies and algorithms for coordinating EV charging loads based on short-term forecasts of renewable energy availability and distribution network conditions. Using realistic distribution system and mobility models, the research would aim to demonstrate how aggregating EV charging can help mitigate overgeneration events from renewables which often cause curtailment. Coordinated charging could help absorb excess renewable energy to charge EVs when it is most abundant, relieving constraints on the grid. This could enable higher penetrations of renewable resources on constrained urban distribution circuits. The coordination algorithms would balance electricity costs with EV owner needs/preferences. The work could guide utilities on optimizing EV charging infrastructure investments.

Idea #5: Design of a Next-Generation Implantable Biomedical Neural Interface based on Graphene Electronics

Neural interfaces that can directly interface with the brain hold promise to treat many neurological disorders and injuries. Current metal-based electrode technologies face longevity issues from surrounding tissue response. For a thesis, a student could design a fully implantable biomedical neural interface prototype built entirely using emerging graphene-based electronic and sensing components. Compared to silicon and metals, graphene offers properties potentially better suited for long-term implantation like flexibility, weakness, and chemical stability. The design would leverage graphene-based transistors, electrodes, communications and power management circuitry. Its in-vivo performance could be rigorously evaluated using tissue-mimicking gel phantoms and animal models over long durations (6-12 months). Outcomes would demonstrate whether graphene interfaces can outperform metal alternatives in reducing inflammatory response, maintaining stable performance, and supporting higher-resolution neural recording and stimulation over chronic timescales. Such a platform could ultimately enable long-term brain-computer interfaces as research devices or clinical therapies.
