Adequate electrical transmission and distribution networks capable to cater for extensive renewable energy utilization in Australia

Abstract

The study portrays the present state of electricity generation and distribution in Australia and simulates the case where electrical transmission networks are interconnecting the eastern to the western parts of the continent. Adequate electrical transmission systems are required for allowing a transfer of renewable energy from generation sites to end-users in a reliable and economically sound manner. Further on, because the amount of energy needed at a particular location is seasonal and daytime specific, a capable transmission system shall be helping making use of time differences to transfer energy from locations on low-demand to others on high demand. Queensland in Eastern Australia, at off-peak times might supply Western Australia at soaring demand, Tasmania might supply the main land with wind electricity, while the solarrich Northern and Central Queensland might supply load centres in states of Victoria and Southern Australia. Results are demonstrating that building interconnecting electrical networks of adequate carrying capacity covering long distances between different time-zones shall be improving services and economics of electrical power transmission and distribution.
