a b s t r a c tIn this work, we examine the potential advantages of co-locating wind and energy storage to increase transmission utilization and decrease transmission costs. Co-location of wind and storage decreases transmission requirements, but also decreases the economic value of energy storage compared to locating energy storage at the load. This represents a tradeoff which we examine to estimate the transmission costs required to justify moving storage from load-sited to wind-sited in three different locations in the United States. We examined compressed air energy storage (CAES) in three ''wind by wire'' scenarios with a variety of transmission and CAES sizes relative to a given amount of wind. In the sites and years evaluated, the optimal amount of transmission ranges from 60% to 100% of the wind farm rating, with the optimal amount of CAES equal to 0-35% of the wind farm rating, depending heavily on wind resource, value of electricity in the local market, and the cost of natural gas.

“…Unfortunately, high temperatures have shown to be very harmful for oxide layers in SiC MOSFETs [34], [35] and, therefore, this is one of the limiting factors for OC capability at present. The third difference is that SiC has a much higher Young's modulus than Si [36], [37], which implies that a SiC die is much stiffer than its Si counterpart, and that this difference in stiffness results in larger thermomechanical stresses, especially in the die attach [17], [18] [19], [20] [21] [22], [20], [16] [23] [24] below the corners of the chip during OC events [38]. This problem is accentuated as the chip size increases and, hence, it relates to the fourth difference, which is that SiC chips at present are typically smaller than Si chips due to material and process-related yield issues [39].…”

With the increase in penetration of power electronic converters in the power systems, a demand for overcurrent/overloading capability has risen for the fault clearance duration. This article gives an overview of the limiting factors and the recent technologies for the over-current performance of SiC power modules in power electronics converters. It presents the limitations produced at the power module level by packaging materials which include semiconductor chips, substrates, metallization, bonding techniques, die attach, and encapsulation materials. Specifically, technologies for over-current related temperatures in excess of 200 • C are discussed. The paper also discusses potential technologies which have been proven or may be potential candidates for improving the safe operating area. The discussed technologies are use of phase change materials below the semiconductor chip, Peltier elements, new layouts of the power modules, control and modulation techniques for converters. Special attention has been given to an overview of various potential phase change materials which can be considered for high-temperature operations.

“…Another example is found in WECC system in February 2010 when mal-functioning of power plant led to very large amplitude FO [4]. FOs have been found in Intermountain Power Project (IPP) [14] HVDC line on March 6, 1987 [3].…”

This paper presents a systematic approach to detect the frequency of Forced Oscillation (FO) in real-time signals obtained from phasor measurement units (PMUs). It is shown that, preprocessing of the signal by Empirical Mode Decomposition (EMD) technique leads to effective detection. The designed methodology can detect the frequency of FOs even in the presence of multiple mode mixing, whereas the self-coherence method fails to detect. Spectral analysis is performed on the Intrinsic Mode Functions (IMFs) to determine the frequency of FO. To further confirm the sustainability of the oscillation, spectral analysis of timedelayed signals is also performed and the results are discussed. The study is investigated on both simulated signal and real-time PMU signal of North American SynchroPhasor Initiative (NASPI). Two forced oscillations; FO 1 (14.67 Hz) and FO 2 (4.62 Hz) are detected in the NASPI PMU's signal by the proposed approach. Keywords-Forced oscillations; power spectral density (PSD); empirical mode decomposition (EMD); North American synchro phasor initiative (NASPI).
