Abstract:The competing interests of utility power generation companies, residential photo-voltaic (PV)
system installers, and residential PV system manufacturers has created an assortment of
contradictory viewpoints concerning the capacity of electrical grids to include renewable
energy expansion. A frequent conflict created within this environment is that between utility
companies, who have the final authority on whether or not to grant PV system installation
licenses, and individual home owners and residential developers seeking the energy savings
benefits that PV systems can provide for their homes. The general explanation offered by
utility companies as the basis for whether or not they grant installation licenses is their
estimation of grid saturation on the secondary of the substation that the license applicant is
supplied by. While the definition of when a substation has reached its saturation point will
vary between utility companies, the saturation point itself is generally determined by a
comparison of the estimated minimum expected load on a given substation during the hour of
peak PV generation capacity to the rated power of the expected peak PV generation itself
during that hour. With there being no current legal requirements for utilities to publish their
actual loading or determination assumptions for saturation, home owners and residential
developers currently have no established method to contradict the utility company's
estimation and provide evidence that their substation can support the introduction of
additional PV systems without adverse effects. The intent of this Thesis is to propose a
novel, bottom-up modeling approach and to outline the general requirements necessary for
the repeatable creation of accurate and flexible simulations that can demonstrate the real
world effects of the integration of residential PV systems onto existing electrical distribution
systems
