Item type:Publication, Application of electrolyzer system to enhance frequency stabilization effect of microturbine in a microgrid system(2009-09-01) ;Vachirasricirikul, Sitthidet; It is well known that the power output of microturbine can be controlled to compensate for load change and alleviate the system frequency fluctuations. Nevertheless, the microturbine may not adequately compensate rapid load change due to its slow dynamic response. Moreover, when the intermittent power generations from wind power and photovoltaic are integrated into the system, they may cause severe frequency fluctuation. In order to study the fast dynamic response, this paper applies electrolyzer system to absorb these power fluctuations and enhance the frequency control effect of microturbine in the microgrid system. The robust coordinated controller of electrolyzer and microturbine for frequency stabilization is designed based on a fixed-structure H<inf>∞</inf> loop shaping control. Simulation results exhibit the robustness and stabilizing effects of the proposed coordinated electrolyzer and microturbine controllers against system parameters variation and various operating conditions.

Item type:Publication, Impact of Background Interference on Signal-To-Noise Ratio in Heat-Assisted Magnetic Recording(2018-01-01); ;Chaiduangsri, NuttaponTongsomporn, DamrongsakWe discuss background interference (BGI) arising from the read-back of preexisting data and adjacent tracks on a recording medium. A signal-To-noise ratio analysis is used to measure the impact of BGI in heat-Assisted magnetic recording in a spin-stand tester. The signal-To-noise ratio for a data track with an alternating field background was compared to a data track written over a pair of background tracks. We considered the effect of background track offsets: The distance between the background and data tracks. BGI, which depends on the background track offset, can degrade read-back performance. The dibit extraction technique is able to separate the linear dibit response and the BGI in the read-back waveform.
