Overview
A hybrid AC/DC microgrid with photovoltaic generation, diesel backup and battery storage using coordinated power and SOC management.
The subject is especially relevant to electrical matlab simulink projects because it combines AC/DC power balancing, battery SOC control, diesel dispatch and interlinking-converter coordination. A useful research model must not only run successfully; it should also expose the variables needed for validation, comparison and technical discussion.
Why This Project Topic Matters
Hybrid AC/DC Microgrid Energy Management Using PV, Diesel & BESS - MATLAB Simulink provides a practical platform for studying dynamic behavior under realistic commands, parameter changes and disturbances. It can be used as a baseline implementation before introducing optimization, intelligent control, fault diagnosis or advanced energy-management functions.
For thesis and final-year work, the topic supports clear objectives, measurable performance indicators and multiple extension paths. The model can therefore support methodology chapters, result interpretation and comparison with alternative algorithms.
System Architecture
A complete simulation is normally organized into the following functional blocks:
- PV array and DC-DC converter
- Battery energy storage with bidirectional converter
- Diesel generator and governor
- AC and DC buses
- Interlinking converter
- Energy-management and load-priority logic
Recommended Modeling Workflow
- Model AC and DC source, load and converter subsystems.
- Implement PV power extraction and DC-bus regulation.
- Use battery charge-discharge logic within SOC limits.
- Start or unload the diesel generator according to power deficit.
- Coordinate the interlinking converter and test source and load transitions.
Control and Analysis Approach
The main engineering objective is AC/DC power balancing, battery SOC control, diesel dispatch and interlinking-converter coordination. The controller or analysis layer should be designed around physically meaningful measurements, realistic operating limits and clearly defined reference values.
Validation should include at least one steady operating condition and several transients. Useful scenarios include command changes, source variation, load steps, parameter uncertainty and disturbances relevant to the physical system.
Important Results to Record
- AC and DC bus voltage
- PV, diesel, BESS and load power
- Battery SOC and converter current
- System frequency
- Power balance and operating-mode transitions
Each graph should be labeled with units and the event timing should be stated. Where possible, calculate quantitative indicators such as rise time, settling time, overshoot, ripple, efficiency, THD, tracking error or energy consumption rather than relying only on visual comparison.
Research Extensions
- Remote and islanded microgrids
- Diesel fuel-reduction studies
- Hybrid energy-management research
- Resilient distributed-energy systems
- Replace the baseline controller with fuzzy, neural-network, predictive or optimization-based control
- Perform robustness and parameter-sensitivity analysis
- Develop a comparative study using identical test conditions
- Prepare controller logic for real-time or hardware-in-the-loop implementation
