Abstract
Liberalization of electricity markets has brought focus on the optimal use of generation and transmission infrastructure. In such a scenario, where the power transmission systems are being operated closer to their critical limits, Ancillary Services (AS) play an important role in ensuring secure and cost-effective operation of power systems. Emerging converter-based HVDC technologies and integration of renewable energy sources (RES) have changed the power system dynamics which are based on classical power plant operation and synchronous generator dynamics. Transmission system interconnections between different countries and integrated energy markets in Europe have led to a reduction in the use of energy from non-renewable fossil-based sources. This review paper gives an insight into ancillary services definitions and market practices for procurement and activation of these ancillary services in different control areas within the European Network of Transmission System Operators for Electricity (ENTSO-E). The focus lies particularly on ancillary services from HVDC systems. It is foreseen that DC elements will play an important role in the control and management of the future power system and in particular through ancillary services provision. Keeping this in view, the capability of HVDC systems to provide ancillary services is presented.

In a vertically integrated power system, the main task of the system operator is to operate the power system in a reliable and secure manner
Ancillary services play a pivotal role in ensuring reliable power system operation
It is critical that various power system equipments which can provide these services could be used in an economical way while enabling smooth power system operation
Summary
In a vertically integrated power system, the main task of the system operator is to operate the power system in a reliable and secure manner. The ancillary services for frequency control has been categorized as regulation and contingency by Australian Energy Market operator [6] whereas in Europe as per guidelines on electricity balancing the frequency control services are known as frequency containment reserves, frequency restoration reserves and replacement reserves [7]. A review of ancillary services definitions, procurement, and implementation methods in different ENTSO-E areas is presented.
