Virtual Inertia Control applied to a Multi-area Electrical Power System with Low Inertia and High Penetration of Renewable Energy Sources.

The integration of renewable energy sources in modern electrical power systems faces with many challenge to deal with the operation, control, and protection of an electrical power system. This is mainly because renewable energy sources, when interconnected to the network through electronic devices, do not provide inertia to the system which in turn may cause frequency stability issues and cause system crash. To solve these problems, this work proposes to emulate the behavior of a synchronous machine and provide frequency support through virtual inertia control. Along the emulation, the derivative method connected to an energy storage source is analyzed to provide frequency support to a multi-area control network with a high integration of renewable energy sources which is also useful to analyze the dynamic behavior of the system in the face of load variations.
