U.S. Patent No. U.S. 7,248,946 B2
Inverter Control Methodology for Distributed Generation Sources Connected to a Utility Grid
Abstract: The present invention provides an improved control methodology for maximum power point tracking (MPPT), anti-islanding, and output current regulation for distributed generation sources connected to the utility grid. The control includes enhancements for MPPT and regulating the inverter output current that is sourced into the utility grid. In addition, the functions associated with MPPT, anti-islanding detection, and output current regulation are integrated together; the MPPT algorithm operates in conjunction with the anti-islanding detection, and the output current regulation operates in conjunction with the MPPT algorithm.
AEC continues to develop state-of-the-art technologies that address today’s energy and environmental needs in ingenious ways. As new applications for these technologies are continuously discovered, AEC and TerraWatt Power intend to vigorously protect their technology and market position through an aggressive program of patent protection.
