Project Objective
Maintain stable AC frequency, AC voltage and DC-bus voltage while coordinating renewable generation, diesel dispatch and BESS charge/discharge across changing generation and load conditions.
The page is written to help researchers move from a project title to a structured model, a defendable simulation methodology and a clear set of result graphs without claiming fixed performance before the final parameters are selected.
System Architecture and Main Blocks
- AC microgrid with diesel synchronous generator and AC loads
- DC microgrid with PV source, DC–DC converter and DC loads
- Battery energy-storage system with bidirectional converter
- Bidirectional AC/DC interlinking converter
- PV MPPT, DC-bus voltage, frequency and power-control loops
- Supervisory energy-management and source-priority logic
MATLAB Simulink Methodology
- Define AC/DC load profiles, PV rating, diesel limits and BESS capacity.
- Validate each source and converter independently before interconnection.
- Set interlink-converter control for active-power exchange and bus support.
- Implement source-priority, SOC limits and diesel start/stop or power-reference rules.
- Apply irradiance changes, load steps and islanding transitions while logging bus and source variables.
Recommended Simulation Scenarios
- High PV generation with battery charging
- Low PV generation with diesel and BESS support
- AC-load and DC-load steps
- BESS SOC upper/lower limit transition
- Interlink-converter power reversal and islanded operation
Expected Outputs and Performance Metrics
- AC-bus voltage and frequency
- DC-bus voltage and ripple
- Diesel, PV, BESS and interlink-converter power
- Battery SOC, current and charge/discharge state
- Power balance, load supply continuity and transient response
Results should be plotted with labelled axes, units, reference signals and event times. Baseline and proposed-control cases should use the same operating conditions for a fair comparison.

Suggested Report Structure
A strong report can include problem definition, literature review, governing equations, system block diagram, parameter table, controller design, simulation cases, result discussion, limitations, proposed novelty and future scope. Screenshots should be accompanied by technical interpretation rather than presented without explanation.
