Topic > Wind Energy in Australia - 883

Wind energy is one of the most commercially reliable and cost-effective renewable energy (RE) resources available anywhere in the world and its use in Australia is undoubtedly a advantageous prospect. Initially, wind energy generation is produced through the movement of air from high pressure to low pressure, since this progression is a direct consequence of solar heating of various parts of the Earth's atmosphere and its planetary movement, resulting in air is deflected to the right in the Northern Hemisphere and in the opposite direction in the Southern Hemisphere (Duffie and William, 2013). It is generally observed that wind energy generation is the most suitable source for Australia's future as it is clean, low cost (compared to other renewable sources), emissions free (except during construction, transport and deconstruction) , widely available and has the highest annual global energy rates among all renewable sources (estimated at 26.7% in 2011) (GM Shafiullah et al, 2011). In a commercial context, Macintosh and Downie (2006) compare the cost of wind and coal generation and suggest that the average price of wind generation was around 60-80 AUD per/MWh, while coal observed a price of AUD $21-40 per/MWh. However, thanks to technological advances in recent years, the price of wind turbines has steadily decreased to the point that they may actually have the same (or lower) market value as coal production (Valentine, 2010). While there are some regions in Australia where wind generation is more plausible, analytical statistics have established that Tasmania is the most appropriate location to establish a wind farm. The computer software known as HOMER (Hybrid Optimization Model for Elect...... middle of paper ...... evident in wind turbines and as a result, this results in uncontrollable consumption of reactive power and low factor of power, voltage distortion problems and drastic changes in voltage and, consequently, considerable line losses (GM Shafiullah, 2012). Therefore, more care must be taken when using the different designs to minimize the PQ loss .
