Abstract: This paper presents the application of information gap decision theory (IGDT) to deal with uncertainties associated with load forecasting in dynamic, environment constrained, coordinated generation and transmission expansion planning. Traditionally, the gaseous emissions are constrained over the whole system. Conventional methods cannot guarantee a practical expansion plan since huge emissions can still occur on some buses in the power system. This paper introduces a per-bus emission limit to avoid extreme emissions in highly populated areas. The effect of nodal emission limits is fully discussed and compared to a conventional method. The model is kept linear using the big M approach to decrease the model computational burden. Reliability is considered by limiting the estimated load not served in each year over the planning horizon. The cost of fuel transportation and fuel limits are considered in order to make the model more realistic and practical. The effectiveness of the proposed model is verified by implementation on Garver 6 bus, IEEE 30 bus, and 118 bus test systems.

Abstract: Current methods used for the measurement of stiffness and d ing of spindle motor bearings used in hard disk drives use a vibration base driven by an external actuator. Acceleration sensors and displacement sensors installed onto the vibration base are then used to measure the acceleration and the spindle runout, respectively. Outputs from these sensors are analysed and used for the calculation of the stiffness and d ing. The method, used for direct measurement and monitoring of total stiffness and d ing, and proposed in this article does not require the use of any additional external sensors, neither does it require a vibration base driven by an external actuator. Vibration is generated by introducing a known value of imbalance onto the spindle motor. The vibration generated is then measured by reading and analysing the position error signal written on the disk surface and subsequently, used to calculate the total stiffness and d ing. Experimental results verifying the proposed method are presented.

Abstract: The penetration and integration of renewable energy sources into modern power systems has been increasing over recent years. This can lead to frequency excursion and low inertia due to renewable energy sources’ intermittency and absence of rotational synchronous machines. Battery energy storage systems can play a crucial role in providing the frequency compensation because of their high r rate and fast response. In this paper, a decentralized frequency control system composed of three parts is proposed. The first part provides adaptive frequency droop control with its droop coefficient a function of the real-time state of charge of battery. The second part provides a fully decentralized frequency restoration. In the third part, a virtual inertia emulation improves the microgrid resilience. The presented results demonstrate that the proposed control system improves the microgrid resilience and mitigates the frequency deviation when compared with conventional ω -P droop control and existing control systems. The proposed control system is verified on Real-Time Digital Simulator (RTDS), with accurate microgrid model, nonlinear battery models and detailed switching models of power electronic converters.

Abstract: One of the major sources of vibrations in hard disk drives (HDDs) is unbalance caused by an uneven distribution of the mass on the rotational part of the HDD. Vibrations are limiting the increase in the storage density of the HDDs therefore it is of paramount importance to identify major sources of vibrations and to reduce them to the minimum level. This paper proposes a new passive balancing algorithm which can achieve significant reduction in the HDD unbalance at low cost and with a high yield rate. The unbalance reduction is achieved using a balancing ring with a large number of holes which are used for the placement of balancing masses of a given weight. The optimum number and position of the balancing masses is then found in order to reduce the residual unbalance to minimum level. Guidelines on optimum selection of the correction mass are also proposed.
