Residential PVs and EVs: Before and After
MetadataShow full item record
Power distribution systems are experiencing higher load levels, unbalanced distributed generation, a wealth of load diversity, and more uncorrelated events than ever before. To provide quantitative information regarding the changes, this paper contrasts the electrical state of the largest Smart Grid residential community in Austin, Texas before and after the proliferation of its PVs and EVs. This community is the research focus of the authors, local utilities, and many others attempting to hinder detrimental consequences of the uncontrolled, fast proliferation of residential assets on the grid. The authors use surface and filled contour plots to show new electrical footprints, and show its impact on transformer utilization, feeder demand, current unbalance, and distribution losses.
