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 …

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 …
