Superconducting Magnetic Energy Storage Systems For Power System Applications, Danny Soetanto, K.W.E Cheng
Professor Darmawan Sutanto
Advancement in both superconducting technologies and power electronics led to High Temperature Superconducting Magnetic Energy Storage Systems (SMES) having some excellent performances for use in power systems, such as rapid response (millisecond), high power (multi-MW), high efficiency, and four- quadrant control. This paper provides a review on SMES applications to power systems.
Hybrid Fuel Cell And Energy Storage Systems Using Superconducting Coil Or Batteries For Clean Electricity Generation, Danny Soetanto, Kai Ding
Hybrid Fuel Cell And Energy Storage Systems Using Superconducting Coil Or Batteries For Clean Electricity Generation, Danny Soetanto, Kai Ding
Professor Darmawan Sutanto
This paper described a novel design of a hybrid fuel cell and energy storage system using high temperature superconducting energy storage system (HT-SMES) or batteries to meet fast changing load. The power electronic switches in the converter of the energy storage system are controlled in such a way that the amplitude and waveform of the inverter output current from the fuel cell is tightly regulated to follow a sinusoidal reference waveform. In this way, the energy storage system is used to supply the fast changing part of the load and the fuel cell system continuously supplies a constant full load …

Improved Controller For High Temperature Super Conducting Magnetic Energy Storage (Hts-Smes), Danny Soetanto, M Aware
Professor Darmawan Sutanto
This paper describes a novel controller for a High Temperature Superconducting Magnetic Energy Storage (HTSSMES) that can ensure (a) fast return of energy to the superconducting coil under constant current mode and (b) a constant and sinusoidal input supply current irrespective of the varying load demand with and without harmonics. A special feature of this controller is its ability to smoothly charge the superconducting coil using constant current charging so that it can be ready for the next discharging operation as soon as possible. Analysis of the circuit operation under hysteresis control is presented in details. Simulation and experimental results …

Monte Carlo Study Of The Energy Response And Depth Dose Water Equivalence Of The Moskin Radiation Dosimeter At Clinical Kilovoltage Photon Energies, C Lian, M Othman, D Cutajar, M Butson, Susanna Guatelli, Anatoly Rosenfeld

Skin dose is often the quantity of interest for radiological protection, as the skin is the organ that receives maximum dose during kilovoltage X-ray irradiations. The purpose of this study was to simulate the energy response and the depth dose water equivalence of the MOSkin radiation detector (Centre for Medical Radiation Physics (CMRP), University of Wollongong, Australia), a MOSFET-based radiation sensor with a novel packaging design, at clinical kilovoltage photon energies typically used for superficial/orthovoltage therapy and X-ray CT imaging. Monte Carlo simulations by means of the Geant4 toolkit were employed to investigate the energy response of the CMRP MOSkin …

Effect Of A Magnetic Field On The Track Structure Of Low-Energy Electrons: A Monte Carlo Study, M Bug, E Gargioni, Susanna Guatelli, S Incerti, H Rabus, R Schulte, Anatoly Rosenfeld

The increasing use of MRI-guided radiation therapy evokes the necessity to investigate the potential impact of a magnetic field on the biological effectiveness of therapeutic radiation beams. While it is known that a magnetic field, applied during irradiation, can improve the macroscopic absorbed dose distribution of electrons in the tumor region, effects on the microscopic distribution of energy depositions and ionizations have not yet been investigated. An effect on the number of ionizations in a DNA segment, which is related to initial DNA damage in form of complex strand breaks, could be beneficial in radiation therapy. In this work we …

A Comparison Of X-Ray And Proton Beam Low Energy Secondary Electron Track Structures Using The Low Energy Models Of Geant4, Aimee Mcnamara, Susanna Guatelli, Dale Prokopovich, Mark Reinhard, Anatoly Rosenfeld
Susanna Guatelli
"Purpose: Lethal cell damage by ionising radiation is generally initiated by the formation of complex strand breaks, resulting from ionisation clusters in the DNA molecule. A better understanding of the effect of the distribution of ionisation clusters within the cell and particularly in regard to DNA segments could be beneficial to radiation therapy treatment planning. Low energy X-rays generate an abundance of low energy electrons similar to that associated with MeV protons. The study and comparison of the track structure of photon and proton beams could permit the substitution of photon microbeams for single cell ion irradiations at proton facilities …

Monte Carlo Study Of Mosfet Packaging, Optimised For Improved Energy Response: Single Mosfet Filtration, M Othman, D Cutajar, Nicholas Hardcastle, S Guatelli, Anatoly Rosenfeld
Susanna Guatelli
Monte Carlo simulations of the energy response of a conventionally packaged single metal-oxide field effect transistors (MOSFET) detector were performed with the goal of improving MOSFET energy dependence for personal accident or military dosimetry. The MOSFET detector packaging was optimised. Two different ‘drop-in’ design packages for a single MOSFET detector were modelled and optimised using the GEANT4 Monte Carlo toolkit. Absorbed photon dose simulations of the MOSFET dosemeter placed in free-air response, corresponding to the absorbed doses at depths of 0.07 mm (Dw(0.07)) and 10 mm (Dw(10)) in a water equivalent phantom of size 30 x 30 x30 cm3 for …

We present MLE+, a tool for energy-efficient building automation design, co-simulation and analysis. The tool leverages the high-fidelity building simulation capabilities of EnergyPlus and the scientific computation and design capabilities of Matlab for controller design. MLE+ facilitates integrated building simulation and controller formulation with integrated support for system identification, control design, optimization, simulation analysis and communication between software applications and building equipment. It provides streamlined workflows, a graphical front-end, and debugging support to help control engineers eliminate design and programming errors and take informed decisions early in the design stage, leading to fewer iterations in the building automation development cycle. …

The largest source of carbon dioxide emissions globally is the combustion of fossil fuels (coal, oil and natural gas) in power plants, automobiles, industrial facilities and other sources. Generating electricity is the single largest source of carbon dioxide emissions, representing 41% of all emissions. Since 2007 the United States has been more actively considering nuclear power as an option for developing energy. Three decades after the Three Mile Island accident seemed to doom the nuclear power industry, the idea of a nuclear renaissance has been gaining public acceptance as a way to generate energy without greenhouse gas emissions and meet …
