3.2.7 Variation of active and reactive power This method varies the output power injected by inverter and monitors the variation in voltage amplitude and frequency to detect islanding. For example, when a microgrid is islanding, the active power of DG will flow into the load. To balance the ...
Empirical formulae of optimum weight factors as functions of the reference active and reactive power signals are proposed and mathematically derived. The investigated FCS-MPC control scheme is incorporated with the LVRT function to support the grid voltage in fulfilling and accomplishing the up-to-...

MCP:This distributed and reactive transport protocol for DCNs provides the right transmission rates to achieve minimal per-packet delay and meet flow deadlines. MCP does not modify any hardware switch and incremental deployment supporting it. This protocol is similar with other TCP flavors modified fo...
