Power Conditioning for Grid-Connected PV Systems Less Than 250 KW

摘要

Power conditioning development for grid-connected photovoltaic (PV) applications has been underway for the past five years at Sandia Laboratories. Although the dc source is a photovoltaic array, many of the advances and lessons learned have general applicability to any dispersed generation source connected to the electric utility grid. Progress in single phase (2 to 10 kW) and three phase (20 to 250 kW) hardware will be covered. Results from a detailed hardware evaluation program will be reviewed. Cost and efficiency experience and future projections will be summarized. (ERA citation 09:032910)
