Gas and Electricity Markets

1
Gas and Electricity Markets

• Aim of Module
• The aim of the module is to develop a detailed
  understanding of the issues associated with
  modern electricity and gas markets. The module
  will focus on the overall design objectives of
  these markets, the variety of models which have
  been developed worldwide, and on the operation
  and performance of these markets. Associated
  issues including demand forecasting, ancillary
  services and network access will also be
  considered.

Wind Energy for Electricity Supply

• Aim of Module
• The aim of the course is to develop a detailed
  understanding of the issues associated with the
  development of wind energy for electrical energy
  supply.
• The course will focus on the current state of
  wind energy development domestically and
  internationally and will consider the future
  development of wind resources.

6
Learning Objectives

• A good understanding of the role which wind
  energy plays and can play in the electricity
  supply system and its role in meeting the
  countrys obligations in terms of greenhouse gas
  abatement.
• Develop knowledge regarding wind energy resources
  and its assessment.
• Develop an understanding of the construction,
  characteristics and performance of wind turbines.
• Develop detailed knowledge relating to the
  electrical and control aspects of wind turbines,
  including design and operational issues.
• Develop an understanding of the siting of wind
  turbines and wind farms and on the issues
  associated with their integration into supply
  networks.

Range of Technical Problems

• Variability of wind farm output due to changes in
  wind speed
• Selection of best wind power sites to allow for
  economic return, while meeting environmental,
  planning, etc. constraints
