Recent tendencies indicate that new and reconductored power lines are declining from the traditional cross arm mounted overhead connection types. Instead of the traditional connections, underground cables are increasing as it is one of the most popular choices. At the same time, LVABC is another type of overhead cable spreading in distribution networks, which has a bundled property similar to the...
This paper studies reliability benefits of wind energy in two different systems in Australia: New South Wales and Victoria. Reliability assessment has been conducted in generation system level and a time dependent clustering method is applied to model wind power. This technique not only can capture time dependent attributes of wind energy, but also is capable of keeping the correlations between wind...
This paper investigates the impacts of rooftop photovoltaic (PV) penetration as well as gas market uncertainties on the generation planning decisions. These issues are paramount in the state of Queensland in Australia that has traditionally been reliant on coal based generation. A Generation Expansion Planning problem is used to evaluate alternative generation development scenarios for Queensland...
Power systems around the world are impacted by increasing penetration of Distributed Generations (DGs), which, in many cases, results in higher fault current levels. In some cases the increased fault current level may exceed the rating of the existing Circuit Breakers (CBs). Since fault current levels are, to a large extend, influenced by the network parameters and topology, which are not easily changed,...
Modern electricity distribution networks are facilitated with a high share of renewable generation, especially solar photovoltaics (PV). PV source results in fluctuating power injection and bi-directional power flow in a system, which can introduce overvoltage problem in low voltage (LV) networks. Using battery energy storages can mitigate this problem. This paper proposes a tool, which searches for...
