This paper reports on future electricity generation scenarios modelled using NEMO, a model that applies a genetic algorithm to optimise a mix of simulated generators to meet hourly demand profiles, to the required reliability standard, at lowest overall industry cost. The modelling examined the least and near least cost technology portfolios for a scenario that limited emissions to approximately one...
Silicone oil is a promising alternative insulating liquid especially for the sites where fireproofing and environment protection must be considered. In this paper, the chemical and dielectric performance of silicone oil-paper composite insulation system under thermal aging is discussed. Two kinds of oil-paper systems are tested: mineral oil and silicone oil (Shin-Etsu Chemical KF-96-20 Lower viscosity...
Partial discharge (PD) site in high voltage power equipment can be located by solving the time difference equations. Estimating the time difference between PD signals with high accuracy is of great importance for accurate locating. This paper presents a time difference determining algorithm using cumulative energy function and differential energy method. The differential energy characterize the increase...
In order to accurately calculate power systems available transfer capability (ATC), this paper proposes anew model including FACTS devices for calculating transfer capability with the "N-1" static stability margin constraints. Based on the teaching- learning-based algorithm (TLBO), an improved teaching-learning algorithm (ITLA) is put forward which is able to deal with complicated nonlinear...
Electric vehicles (EVs) is an attractive solution to replace traditional petrol cars. The penetration of EVs posts a challenge for power systems since it would inevitably incur undesirable voltage drops. EV load shedding can be performed to regulate the grid voltage. The EV charging location is also an important factor when shifting the EV loads. This paper presents a new schedule-controlled framework...
This study assesses the potential impact of high renewable generation on the spot electricity prices, generator revenue and profits in an energy-only electricity market. In particular, it presents modelling outcomes for the Australian National Electricity Market (NEM) with a range of possible renewable penetrations in 2030. It is assumed that the current reliability standard is maintained and participants...
The interest for installation of solar Photovoltaic (PV) systems in the distribution network has been increasing due to their declining cost and high electricity price from the utilities. On the downside, the PV power generation is sensitive to the variation in solar irradiation, which can cause potential challenges in the low voltage network in terms of voltage quality and management. In this research,...
In Australia, grid integration of renewable energy (RE) resources has been very popular due to public awareness of climate change and favorable government policies. The initial mandatory renewable energy target (MRET) has been successful and there has been a revised target (RET) set for next decade. On the other hand, there are some regulatory and technical issues posing hindrances to the development...
