Outline of Final Research Achievements

In this project, a coordinated control system for suppressing frequency fluctuations of a power system with wind farm and photovoltaic station installed has been constructed, which is composed of power flow control of HVDC interconnection line and input/output control of battery. In addition, a virtual inertia control system utilizing inertial energy of a variable speed wind power generator has been constructed in order to improve instability of the power system whose inertia is decreased due to introduction of such natural energy electricity sources. Effectiveness of the coordinated control system composed of HVDC interconnection line and battery, and that of the virtual inertia control system of the variable speed wind power generator, have been confirmed through simulation analyses.
