Seamless Mode Change between Grid-connected Mode and Islanded Mode for PV Systems

Technology SummaryDistributed generators, including solar power, in the microgrid, must be able to work in both grid-connected mode and islanded mode (the condition in which a distributed generator continues to power a location even though electrical grid power is no longer present), with good transient performances during mode changes. This technology...
