Building modeling, specifically heating, ventilation, and air conditioning (HVAC) load and equivalent energy storage calculations, represent a key focus for decarbonization of buildings and smart grid controls. Widely used white box models, due to their complexity, are too computationally intensive to be employed in high resolution distributed energy resources (DER) platforms without simulation time delays. In this paper, an ultra-fast one-minute resolution Hybrid Machine Learning Model (HMLM) is proposed as part of a novel procedure to replicate white box models as an alternative to widespread experimental big data collection. Synthetic output data from experimentally calibrated EnergyPlus models for three existing …
Evaluating Energy Storage Methods For The Stabilization Of Rural Microgrids, Colin Pennock
Evaluating Energy Storage Methods For The Stabilization Of Rural Microgrids, Colin Pennock
Honors Theses
Microgrids are a hot topic in industry at the moment due to their ability to help integrate renewables into the national grid. However, they are mainly used in urban settings, despite the stability benefits they could provide to rural communities. This research aims to help expand microgrids into a rural context by building a streamlined, phasor-domain model of a microgrid in MATLAB-Simulink’s toolbox Simscape Electrical and using it to evaluate three energy storage options: a national grid connection, battery, and flywheel. My capstone involved testing models of these three solutions by subjecting my overall microgrid to faults typical of a …

The microgrid is the future for the electrical utility system. Because of this, future power engineers need to be well-versed in this topic when they go into industry. Cal Poly has created a microgrid laboratory for this very purpose. However, it is missing its battery based energy storage branch. Due to safety concerns, a traditional chemical battery is not suitable for student use. In order to maintain Cal Poly’s learn-by-doing approach, an alternative solution must be implemented. A regenerative power supply meets the criteria for student use. It is capable of simulating the sinking and sourcing capabilities of a battery …
