Power System Seminars
Power System Seminars
EirGrid is undertaking to run a series of seminars on the Operation of the Power System in EirGrid. These seminars are being run as part of our Customer Services Initiatives and in response to requests from the industry for an opportunity to broaden their knowledge and awareness of Power System Operations.
We are currently planning to run a number of seminars of roughly 2 hours duration each on specific topics for interested parties during 2011. The seminars will take place in the EirGrid offices in Ballsbridge, Dublin 4.
Please see below for a description of the seminars that we are proposing to run during the course of this year:
A day in the Life of the NCC & Managing Power Transmission Flows (9th March 2011)
The National Control Centre operates twenty four seven, 365 days a year to ensure the safe, secure and cost effective delivery of power to all customers at all points on the transmission system. Fundamental to meeting this objective is ensuring that transmission lines and other plant are operated within safe limits and that the power system is managed in such a way that it can withstand a wide range of disturbances without causing supply interruptions.
This seminar will examine the component parts of the transmission system and the laws of physics which dictate how power flows on the network. A typical day in the life of an NCC operator managing the transmission system will be described and some real life examples of faults that have occurred will be discussed. The role of NCC in scheduling and dispatching power stations will be covered in a later seminar.

A Day in the Life of the NCC and Managing Power Flows
Economic Dispatch & Unit Commitment (20th April 2011)
The decisions made in the National Control Center, twenty four seven, 365 days a year in relation to which generators to bring on load (Unit Commitment) and what level of output to place each generator at (Economic Dispatch) have a major influence on power system security, the cost of electricity and the commercial/technical operation of power plant.
This seminar will examine the inputs required to make these decisions, analysis techniques and tools used to convert these inputs into commitment and dispatch decisions and finally how the best made plans can be altered by real world events.
Generation Scheduling, Economic Dispatch and Unit Commitment
Managing Dispatch Balancing Costs (26th May 2011)
This module will set out the role of the TSO to manage constraints and the analysis carried out by the TSOs to explain the main drivers of constraints costs. Settlement figures will be provided by SEMO and the module will include an overview of the constraint calculations in the SEM systems. The TSOs forecast for constraints will also be explained in terms of the methodology and approach to analysis. A Q&A will be facilitated following the presentations.

Wind Forecasting and Dispatch (7th July 2011 - 11am)
Electricity demand in Ireland ranges from summer night valley low of 1786MW up to a winter peak of 5090MW. With over 1500MW of wind generation connected to the transmission system in Ireland, output from wind farms has at times represented up to 50% of the electricity being consumed in the country. With wind representing so much of the generation capacity and having priority dispatch it is essential that the National Control Centre can forecast the output from wind farms with a reasonable degree of accuracy. Furthermore, as wind generation units are not normally manned the National Control Centre (NCC) must have the capability to dispatch down the output from Wind Generation remotely in order to manage system demand and local transmission constraints.
This seminar will examine EirGrid’s experience with wind forecasting over the past ten years, where EirGrid sources its forecasts, how accurate they are and how the NCC interprets them. We will also look at the impact of forecasts being incorrect and how NCC endeavours to manage this uncertainty in a cost effective way. Finally the seminar will give an overview of the tools available to NCC to dispatch wind and the business rules followed by NCC when determining the order in which individual Wind Generation units should be dispatched down.
