Abstract
The purpose of this dissertation was to undertake a feasibility assessment into the design of a residential energy management and metering device (REMD) which incorporates various operating modes that would replace current retail metering devices. The operating modes that are being implemented under this dissertation are known as sustainability mode, traditional mode and benefit mode. The approach was to undertake the design of each of the operating modes based on aspects of environmental, simplicity and cost incentives which would capture majority of users based on their motivations and ethical stand points on power usage which would hopefully lead to greater market uptake.
After completing the literature review it was discovered that such a device which covered both aspects of energy source management and metering was not readily available and limited research into this area had been undertaken. There is however a lot of research into areas of HEMS which deals with the energy management down stream of electrical switchboard and more broadly MGEMS which looks at energy management on a microgrid level. The intent behind the REMD is that it will fill the void between HEMS and MGEMS offering energy source management and metering as another layer to these two existing technologies. Another aspect of importance from the literature review was the type of controller to be implemented and the original goal was to implement a fuzzy logic controller, but after undertaking the methodology it was discovered that this controller type is not the most practicable as the system parameters are well defined and as such a state-based control approach was implemented.
State transition and flow charts were developed to form the main basis behind each of the three operating modes, and from here these were then used to develop models of each of the operating modes. The models were built in Mathworks MATLAB Simulink with the additional stateflow add-on package, which is specifically developed for the design and implementation of state-based controls. Each operating mode was built iteratively and tested once complete with 24-hour data that was then compared against hand calculated values to determine if the code was operating as intended. Once the code was debugged the controller was given a weeks worth of data with various configurations of PVS and BESS sizes to determine how the controller responds in the various operating modes with different energy source configurations.
After simulating the controller it was determined that the REMD is a feasible device and showed positive signs for each of the operating modes. Varying the PVS and BESS had various effects on how the controller responded but the main takeaway is that larger BESS and PVS systems in conjunction with the REMD will offer the users more benefits in their chosen operating modes. This device will require further development and testing before it can become a viable product but this feasibility assessment has created the foundation for further research.
