Reliable, Low-Cost Distributed Generator/Utility System Interconnect: Final Subcontract Report, November 2001-March 2004

Abstract

This report summarizes the detailed study and development of new GE anti-islanding controls for two classes of distributed generation. One is inverter-interfaced, while the other is synchronous machine interfaced.

Power electronics in smart grid distribution power systems: a review

“…In Song et al (2004), Ye et al (2006), Ponnaluri et al (2005), Inoue and Akagi (2006), Salem et al (2015) and Bayoumi (2013b), a field-oriented controlled (FOC) induction machine-based FESS consists of a 20 kHz high-frequency AC link (HFAC-link) and back-to-back pulse density modulated (PDM) converters. The 20 kHz HFAC-link and PDM technology, as shown in Figure 19, provides a convenient means for power management in a multi-terminal converter distribution system, offers flexibility in voltage level changes, and allows single stage power conversion.…”

Advanced Power Electronic Interfaces for Distributed Energy Systems Part 1: Systems and Topologies

“…The control of the utility connected inverter, as shown in Figure 27, is developed with constant power control (Ye et al 2006). Many functions to deal with practical issues are not shown in the diagram, such as the negative sequence regulation, DQ decoupling, etc.…”

“…The cascaded conversion would appear to have redundancy, especially since the topology adds a DC bus that must be filtered. A few topologies exist for cascaded DC-AC and AC-AC cycloconverter for the fuel cell applications (Nikkhajoei and Iravani 2005;Ye et al 2006). In the future, the possibility of using matrix converters as the AC frequency changer will probably introduce more high-frequency link topologies for the fuel cell systems.…”

“…It is still debatable if an inverter should be allowed to regulate voltage during grid-connected operation. The current IEEE 1547 standard does not allow distributed generation to actively regulate voltage, while some people in the industry suggest that voltage regulation may have some positive impact on the grid (Ye et al 2006). Control of the utility-connected inverter is shown with constant power control (see Figure 10).…”

Development of Standardized Power Electronic Components, Subsystems, and Systems for Increased Modularity and Scalability

“…It is still debatable whether an inverter should be allowed to regulate voltage during gridconnected operations. The existing IEEE 1547 Standard does not allow distributed generation to actively regulate voltage, but there is some evidence that active voltage regulation may have some positive benefit to the grid [12].…”
