During the normal operation of a power system, the frequency is regulated within strict limits by adjusting the electrical supply to meet the demand. If the balance between generation and demand is not reached, the system frequency will change at a rate initially determinate by the total system inertia. The total system inertia comprises the combined inertia of most of spinning generation and load connected to the power system. The contribution of the system inertia of one load or generator depend if the system frequency causes change in its rotational speed and, then, its kinetic energy. Worldwide, electricity generation from renewable energy is increasing rapidly; it is especially true in terms of the increasing of the wind power penetration. This situation arises some issues regarding the system frequency control because wind turbines provide small or even none response to frequency changes. Power electronically controlled and/or power electronically connected generators such as DFIG and FPC wind turbines do not naturally provide inertia response. However, inertia response can be emulated by adding a supplementary control signal proportional to the rate of change of frequency, this is named the Synthetic or Artificial Inertia. This approach imposes some challenges about control and protection systems. This workshop is designed to provide a general understanding of the frequency control schemes and frequency response of power systems with the integration of wind power penetration.
