Utility Interface Evaluation for the Sacramento Municipal Utility's First Photovoltaic Plant

摘要

A study of the 1-MW photovoltaic power plant owned and operated by the Sacramento Municipal Utilities has identified and examined some of the effects photovoltaic power systems may have on the operation of the utility grid. The plant contains a single, line-commutated inverter that delivers power to the local 12-kV distribution grid. To monitor harmonics, voltages, energy flows, and other parameters, data were collected a the plant/grid interface, at a power factor correction bank located on the grid, and at the substation feeding the grid. Analyses of the collected data indicate that no adverse effects on the distribution line resulted from operation of the photovoltaic power plant. (ERA citation 11:035756)
