New large-scale connections require cost-efficient designs, must maintain network reliability and security requirements and have a very short time to project completion. Most of the connections also require wide area special protection schemes to ensure the network is operated in a secure, reliable way while maintaining the quality of supply. The majority of Australia’s state […]

The energy sector, which until recently has been very conservative, is now facing increased disruption from increasing penetration of modern variable renewable energy sources. Maintaining the frequency remains a critical metric, but use of existing regulating standards and security mechanisms in place have been deemed ineffective and outdated. The energy sector has historically been immune to […]

High power semiconductor components are changing the scenery for reactive power control in the transmission and distribution sector. The matrix converter is one such reactive power control device which has been enabled by such components and which is finding applications in this field. Current and classical methods of reactive power compensation include fixed capacitor and […]
