Spring 2018:
- Background research on microgrids.
Fall 2018:
Week 2
- More in depth microgrid research.
Week 3
- Microcontroller research and software.
- Arduino Uno was chosen as the best microcontroller to use
Week 4
- Load research (type of loads, power of load, does it need full power, or can it receive half?).
- 3 different types of loads (basic, load, burst).
Week 5
- AC/DC conversion from generation sites research.
- Group meeting so teammates are on the same page
Week 6
- Battery storage research.
Week 7
- Sensors at load, generation sites, and battery storage research.
Week 8
- Microcontroller code and logic research.
Week 9
- Preliminary Simulink testing and simulations.
Week 10
- Finalized Simulink and implemented different scenarios.
Winter 2019:
Week 1
- Finalized microgrid design.
- Started buck converter design.
Week 2
- Ordered micro-controller and other parts.
- Worked on basic PWM code in Arduino.
Week 3
- Tested PWM Arduino code.
- Started feedback code.
- Created RC filter for PWM.
Week 4
- Applied for SRG
- Wired and connected buck converter to Arduino PWM generation
- Looped through different duty cycles to control buck converter output with steady DC power source.
- Found duty cycle thresholds for buck converter.
Week 5
- Implemented sensors to measure voltage and current
- Worked on feedback control using voltage.
Week 6
- Added another voltage source.
- Performed intensive, different scenario, tests.
- Voltage controller did not work with two sources
Week 7
- Changed to a power controller.
- Power controller did not work properly with a load connected.
Week 8
- Changed to a current controller which used the bus voltage, line resistors and the load resistor.
Week 9
- Added multiple loads
Week 10
- Started working on grid connection.
- Current controller was not working properly.
