This paper summarizes the initial investigation of dynamic interactions of voltage regulating equipment when allowed to act together with one or more large voltage-controlled solar photovoltaic (PV) generation plants. The study results are based on an existing large PV plant and distribution circuit in the service area of a major electric utility. The existing feeder does not have any voltage regulating...
Many countries have provided incentives for homeowners, businesses and other entities to install solar photovoltaics (PV) to offset generation from other sources, to reduce the pollution caused by the combustion of fossil fuels. Where incentives are high, significant amounts of solar PV are being installed. The term, high penetration solar, has been defined a number of different ways; sometimes comparing...
In networks feeding loads that vary from low levels during low loading and extremely high levels during high loading conditions, with lines providing supply to these loads being very long, voltage regulation within the acceptable range can be a challenge. In a case where such lines to the load centers constitute parallel corridors with different impedance characteristics, and therefore different loading...
Distributed generation can have an impact on distribution feeder voltage regulation, and distributed solar photovoltaics (PV) are no exception. As the penetration level of solar PV rises over the coming decades, reverse power flow on the distribution feeder will happen more frequently and the associated voltage rise might lead to violations of voltage boundaries defined by ANSI C84.1. The severity...
Electric distribution systems are becoming large and complex leading to higher system losses and poor voltage regulation. This has stressed the need for an efficient and effective distribution network. The main objective of this paper work is to determine optimal location for capacitor placement in radial distribution feeders to improve the voltage profile and reduce the energy loss. This problem...
