We aim to improve HNEI’s grid stability modeling effort (DW) by providing more sources of power quality (PQ) data for integration into their model. Once these initial steps are completed, we will deploy the OPQ Boxes across campus in different configurations for varying amounts of time, as summarized below: These studies all require the manufacturing of 25 OPQ Boxes and the installation of OPQ Hub software on ITS servers. ![]() We propose a series of pilot studies in partnership with OEM that support UH’s goal of net zero by 2035. The following table compares and contrasts the approaches: OPQ technology is open source, inexpensive, quick to procure and install, easy to move from one location to another, and supports multiple monitoring points in a single building to provide more fine-grained insight into power quality. ![]() We propose to complement this capability with an "agile" approach to power quality monitoring, using Open Power Quality ( ) technology developed by Professor Philip Johnson and his students in the Collaborative Software Development Laboratory in the Department of Information and Computer Sciences. These meters take approximately one year to procure and install, cost approximately $10,000 each, and are effectively "permanently" attached to a building's main electrical feed.īuilding-level meters are an appropriate and crucial data collection capability. To that end, OEM is installing building-level meters and using Blue Pillar software to collect and visualize the collected data. To support either generation or efficiency initiatives, UH must develop a high quality understanding of its current electrical grid with respect to both consumption and power quality. Many of these efficiency technologies have more stringent requirements for power quality, and, ironically, some are even known to create power quality problems by pushing "noise" back into their circuits. Examples of this approach include installing variable speed motors on HVAC units, more efficient lights, and Energy Star sub-zero freezers used in many research labs. In addition to improving its energy generation capacity, UH is working toward net zero by reducing energy consumption through improved efficiency. As the grid becomes more unstable and values of frequency, voltage, and THD become more erratic, appliances can fail, and in the worst case, the grid itself must shut down. ![]() A "slightly" unstable grid in which frequency, voltage, and/or THD departs only occasionally and slightly from appropriate values has only "slight" impacts, such as the potential for reduced appliance life. Unfortunately, installation of large amounts of solar generation can make it more difficult to maintain grid stability, which means (in part) maintaining stable and appropriate values for frequency, voltage, and total harmonic distortion (THD). To produce energy, the UH Office of Energy Management (OEM) recommends that UH consider installing up to 17 MW of solar generation on the UH Manoa campus. In general, the net zero mandate requires UH to produce as much energy as it consumes each year. The University of Hawaii system has a net zero power mandate that it is required to meet by 2035. We believe that agile PQ monitoring will provide a complementary, cost-effective means for UHM to collect the data it needs to improve power quality, identify cause and effects, and fulfill its net zero energy mandate, not just during 2018, but for years to come. We propose to complement this effort with "agile" power quality monitoring: our meters cost $100, can be moved easily to different locations, and can assess PQ at any wall outlet location within a building, thus providing high resolution data regarding PQ effects on equipment and caused by equipment. The utility grade meters costs approximately $10,000 installed and are permanently attached to a building's main electrical feed. To obtain this data, UHM is currently installing building-level energy meters that collect both consumption and power quality data. Achieving this requires data useful for creating models of the current UHM microgrid, which can then provide insight into the impact of future solar installation and other energy conservation measures (ECMs) on the UH grid. To achieve net zero energy, the University of Hawaii must install significant solar generation on the Manoa campus while maintaining grid stability. ![]()
