5 FAQs about [Ancillary services power system Rwanda]
What are ancillary services?
The term ancillary services is used to refer to a variety of operations beyond generation and transmission that are required to maintain grid stability and security. These services generally include active power control or frequency control and reactive power control or voltage control, on various timescales.
Should ancillary services be contracted in advance?
However, in systems where the short-term signals are, for whatever reason (e.g. volatility, lack of credibility), insuficient to incentivise investments in resources capable of providing ancillary services in real time, contracting them in advance can be a way to enable or unlock investments.
Why do ancillary services use balancing capacity?
In many ancillary service markets, balancing capacity and balancing energy are jointly procured. Balancing capacity gives TSOs the possibility of activating a certain amount of balancing energy in real time.
How do ancillary services affect economics?
With the unbundling of ancillary services comes the necessity of determining how to pay the providers and charge the users. In this context, it is important to identify some aspects that influence the economics of these services: Ancillary service pricing: determining the price of a specific service.
