Thyristor controlled transformer (TCT) is a kind of static VAR compensator (SVC). It is mainly used to solve the power quality (PQ) problems of low power factor (PF) and three-phase unbalance. However, it pollutes the power system by producing harmonic currents during normal operation. This paper proposed a multi-objective optimal control strategy to improve the comprehensive PQ. Firstly, the total...
Online dynamic load modeling has become possible with the availability of Static Voltage Compensator (SVC) and Phasor Measurement Unit (PMU) devices. The power of the load response to the small random bounded voltage fluctuations caused from SVC can be measured by PMU for modelling purposes. The aim of this paper is to illustrate the capability of identifying an aggregated load model from high voltage...
In this study, we determine the suitable method and timing for the renewal of the voltage control method using voltage control performance evaluated by the maximum photovoltaic (PV) installation rate possible without voltage deviation. The voltage control method is renewed when the voltage of a distribution system deviates with an existing voltage control method. We determine the most suitable voltage...
Inter-connectors are strategically important elements in the power system for their role in bulk power transfer between different areas. The dynamic performance of the interconnector is relatively less certain due to modelling complexity and difficulty in testing, despite its importance to power system security. This paper firstly presents the calibration result of the small signal power system dynamic...
Aurizon, Australia's largest freight railway operator, is investigating the use of Rail Power Conditioner (RPC) technology for load balancing, reactive power compensation and harmonic filtering. The new technology has the capability of replacing Static VAr Compensators (SVC) and Harmonic Filters, and is expected to have a significant impact on the overall costs of railway electrification. This paper...
