Performance evaluation of ancillary services in the Turkish power system

E. Lobato, I. Egido, L. Rouco

Controlling both frequency and voltage has always been an essential role in order to guarantee the secure and reliable operation of a power system. Frequency control is related to active power provision whereas voltage control is related to reactive power support. Within the Turkish Power System, frequency and voltage control have been defined as mandatory remunerable ancillary services that are provided by generating units and managed by the system operator. Under this framework, it becomes of crucial importance for the system operator to monitor the correct provision of these services by the generating agents. This paper proposes a central monitoring system of frequency and voltage control of the Turkish Power System, consisting of a reference model that compares the real operation of the generating units with the desired behavior established by the technical requirements of the Turkish grid code. A number of quantitative measures, based on the deviation between the real and the desired response are proposed to evaluate the adequacy of each unit behavior. Application examples of the central monitoring system are provided using real data of different Turkish power plants.

Keywords: ancillary services, voltage control, frequency control, monitoring system.
