Virtual Inertia Coordinated Allocation Method Considering Inertia Demand and Wind Turbine Inertia Response Capability

Wind turbines can have inertia characteristics similar to synchronous generators through virtual control, which helps provide the support for system. However, there is problem of how coordinate allocation among wind turbines. In response this problem, paper first analyzes capabilities and puts forward an evaluation index that quantifies capability The a farm evaluated at entire system level. Based on index, coordinated method considers demand It proposed release each turbine while avoiding excessive kinetic energy bring second impact by turbines’ exiting operation. Finally, effectiveness verified simulation case study.
