Wind Integration in Australia

摘要

Australia has a large interconnected electricity network on the east coast, connecting the following states; New South Wales, Queensland, Victoria, Tasmania and South Australia. The system is long, near-radial and weakly interconnected. A fault in any area of the system has significant and far reaching consequences (much more than occurs in highly meshed systems). There are also smaller grids in Western Australia and the Northern Territory. At the end of 2005, there was 708MW of wind generation connected into the Australian electricity system, supplying 2,170GWh of electricity in 2005, which equates to 1% of the total electricity produced. There is a large amount of approved projects which will increase the amount of connected wind energy to 2,740MW, which equates to 3.7% of electricity produced. Though 3.7% is a small amount, the state of South Australia has 8.5% of their electricity coming from wind energy which is expected to increase to 20% [1],[2]. The eastern states are fully deregulated into generators, transmission, distribution and retail companies. These companies are public and private.
