PVREG -- a photovoltaic voltage regulation investigation tool: PVREG user's manual

This manual provides essential information for operating the computer program PVREG, a program developed to study the impact of distributed photovoltaic (PV) systems on the voltage regulation of distribution systems. The simulation consists of detailed models of the distribution system's components and a model of solar insolation and cloud systems based on typical meteorological year data. The response of the voltage regulating devices to changes in PV system outputs due to moving cloud systems is determined in discrete time steps. The number of operations of each voltage regulating device is determined, along with the feeder voltage profile. The program structure and a brief description of the models are given. A benchmark case is included to illustrate the use of the various program models.
