Project Description 

Up to now the Irish grid has worked in a relatively simple manner. Humans are creatures of habit so our demand for electricity is reasonably predictable enabling Demand Profiles to be developed and updated year by year to reflect demand growth. Electricity has historically been generated at a small number of large scale generating plants to match predictable demand. In this scenario we have flexible supply meeting inflexible demand. However, as the percentage of variable renewable distributed power generation (DG) increases (up to 42% by 2020 a target set by government White Paper) on the grid problems will arise relating to the balancing of supply and demand. In future scenarios we will have an inflexible load being supplied with variable or intermittent generation with the potential for either a surplus or deficiency of power. A number of technological measures will have to be introduced on both the supply and demand side of the electrical grid system to deal with future power imbalances. An important measure to introduce increased levels of flexibility and load control on the demand side will be “Demand Response” (DR).

My research aims will be to identify suitable DR techniques established from initial research and then apply these to the All-Ireland Grid to determine the performance characteristics, load savings and operational benefits that they will provide.
