2. Ancillary Services Definition: Why?
Ancillary services in the electricity supply sector are defined as services provided by grid operators in addition to the transmission and distribution of electrical energy.
Why?
To ensure secure operation of the power system.

3. Ancillary Services Categories
Frequency Control Ancillary Service (FCAS)
Normal
Frequency Control
Load Following/Regulation
Contingency
Spinning/Non-Spinning/Replacement Reserve
Network Control Ancillary Service (NCAS)
Voltage Support
System Constraints Management
System Restart Ancillary Service (SRAS)
Black Start Support
Island Operation Capability

4. Ancillary Service Provision by Demand Side
Price Paid for Ancillary Services (Great Britain): August 2015
To encourage demand customers to participate in ancillary service provision, National Grid has approved 21 Demand Side Aggregators
Ancillary Service
Market Based
Bilateral Agreements
Mandatory Frequency Response -
£2.78m
Fast Response Reserve
£0.82m
£6.39m
Short Term Operating Reserve
£4.77m
Frequency Control by Demand Management
£10.28m
Obligatory Reactive Power Service
£6.56m
Enhanced Reactive Power Service £0
Total
£31.6m
However, the Demand Side Aggregator has to pass a series of frequency response capability tests outlined by National Grid.
The price paid for ancillary services provision by demand side has doubled in the past year.

10. Summary
Demand side management holds the potential to deliver time critical ancillary services to the grid.
A co-development platform combining simulation and experimentation by means of Real-Time Hardware-in-the-Loop simulations is a step towards benchmarking.
