A Comprehensive Assessment of Markets for Frequency and Voltage Control Ancillary Services

By HDK / Published on Tue, 2009-06-09 12:58

All users of an electrical power system expect that the frequency and voltages are maintained within acceptable boundaries at all times. Some participants, mainly generating units, provide the necessary frequency and voltage control services, called ancillary services. Since these participants are entitled to receive a payment for the services provided, markets for ancillary services have been developed along with the liberalisation of electricity markets. However, current arrangements vary widely from a power system to another.

How does the electricity system function?

By Stefan Fassbinder / Published on Sun, 2006-01-08 16:40

The system that delivers electricity to users is highly complex. While electricity is an omnipresent and crucial part of our everyday economy, understanding this system and all its associated phenomena is not easy, sometimes even for trained electrical engineers. In such a case an intuitive analogy often helps to form a better idea of how things work. We have chosen to compare the electrical system with a tandem bicycle to explain its main characteristics.
