FREQUENCY CONTROL AS AN ANCILLARY SERVICE IN DEREGULATED POWER MARKETS

Abstract

As the penetration of energy from sustainable energy sources like wind, solar and wave are
increasing gradually, the electricity market is moving towards the deregulation. Initially
deregulated markets were mainly focused on the tariff structure of the power systems. After the
effective participation of deregulated market in the whole market environment the technical
activity like frequency control which was considered earlier as a part of integrated electricity
supply, is now considered as an independent service. But in the competitive deregulated market,
it is a challenging job to implement the service which is technical in nature. This paper basically
identifies the technical terms of frequency control and focus on the economic features of it in the
deregulated market, considering it as an ancillary service.
