Island operation capability in the Colombian electrical market: a promising ancillary service of distributed energy resources
Journal Title: TecnoLógicas - Year 2018, Vol 21, Issue 42
Abstract
Nowadays most distributed generators are not designed to operate under islanded conditions. The ancillary service of islanded operation capability is proposed as a technical support service with the ability to increase the reliability, security and flexibility of an electrical distribution system. Nevertheless, island operation entails technical, economic and social issues that must be discussed and analyzed during the planning stage. This articlecompares an intentional island project to a preplanned islandand describes the main issues and benefits of islanded operation. Additionally, the reliability of the service to implement the islanded operation capability as an ancillary service is economicallyassessed, which shows that island-based operation has the potential to minimize non-supplied energy up to 50%. Also, a technical analysis ofimplementing island operation capability ancillary service is presented. Subsequently, an existing electrical distribution system with small hydropower plants is considered as a study case in order to identify the technical requirements set out for both, the distribution system and the generation source. Finally, taking into account the current Lawand regulations, a proposal is outlined for the implementation of the island operation capability ancillary service in the Colombian electrical system.
