Power system dynamic performance: Primary governing frequency response

An efficient ancillary services mechanism implies a good coordination between the regulatory side, transmission system operators and power producers. In continental Europe, ancillary services represent a formal relationship between the actors. The regulatory side establishes recommendations. Transmission system operators adapt them according to the power system specificities and demand the generators elementary participations. For technical and economical reasons, European power producers must have good knowledge of power plant dynamic performance in terms of ancillary services. The performance associated to primary governing frequency response may differ in function of various factors; the most important are the type and the age of the power plant.
