Investigation of the effects of transmission faults upon a renewable energy generating plant

In recent years the number of renewable energy generators connected to Ireland's electricity grid has steadily increased. The Republic of Ireland is now expected to source 13.2% of the electricity it consumes from renewables by 2010, which represents a significant challenge to the electricity system operators and planners. This paper describes the modelling and simulation of a small hybrid wind/hydro generating plant connected to the distribution network. The effects upon the plant of transmission network faults and continuous voltage unbalance are investigated.
