The Electronic Dispatch and Logging (EDL) module interfaces to National Grid (NG) for the exchange of information in near-to real-time as stipulated in the Grid Code.
The EDL module manages communication with the NG EDL messaging interface that is installed at each station or wind farm control point. This module provides access to the NG messaging system, so it allows the Station Operators to submit operational dynamic parameters for the generation assets to NG, and to receive dispatch instructions for Bid-Offer Acceptances and other Ancillary Services. This enables the Station Operators to respond to instructions to change output levels in real-time.
The EDL module supports the following activities:
The EDL module supports the user at the station Control Centre for accepting NG instructions for Balancing and Ancillary Service dispatch, and for creating operational data submissions. The following functionality is provided
A single screen collating all data for rapid emergency submission to NG can be added as an option.
N.B. Where communications with NG are not time-critical, e.g. for submission of planned unit technical parameters, the compilation and submission of data via EDT (Electronic Data Transfer) will be managed through the Genstar4 Power Scheduler module.
The Grid Code requires that each station has a designated control point, at which NG will commission a network line and router, and supply an EDL communication protocol stack (“CTC message client”) for installation on a PC which requires a dedicated network card for the EDL link. The Genstar4 EDL module interfaces to this client to send and receive information for the BM Units which are controlled from that pointing addition, the EDL module manages fully flexible arrangement of BM Units into multiple control-desk configurations, which may be designated as active (controlling) or passive (notification only); and are deployed on other PCs either within the station LAN or across a corporate network, for example at an energy management centre.
Genstar4 also provides full support for dispatching power stations via EDT.
