the piezoelectronic stress transduction switch for very Large Scale Integration low voltage sensor computation and radio frequency applications
Applied Physics Letters, 2015Co-Authors: I B Magdău, X H Liu, Marcelo A Kuroda, Timothy M Shaw, J Crain, Paul M Solomon, Dennis M Newns, Glenn J MartynaAbstract:The piezoelectronic transduction switch is a device with potential as a post–CMOS transistor due to its predicted multi-GHz, low voltage performance on the VLSI-Scale. However, the operating principle of the switch has wider applicability. We use theory and simulation to optimize the device across a wide range of length Scales and application spaces and to understand the physics underlying its behavior. We show that the four-terminal VLSI-Scale switch can operate at a line voltage of 115 mV while as a low voltage-Large area device, ≈200 mV operation at clock speeds of ≈2 GHz can be achieved with a desirable 104 On/Off ratio—ideal for on–board computing in sensors. At yet Larger Scales, the device is predicted to operate as a fast (≈250 ps) radio frequency (RF) switch exhibiting high cyclability, low On resistance and low Off capacitance, resulting in a robust switch with a RF figure of merit of ≈4 fs. These performance benchmarks cannot be approached with CMOS which has reached fundamental limits. In detail, a combination of finite element modeling and ab initio calculations enables prediction of switching voltages for a given design. A multivariate search method then establishes a set of physics-based design rules, discovering the key factors for each application. The results demonstrate that the piezoelectronic transduction switch can offer fast, low power applications spanning several domains of the information technology infrastructure.

electric vehicles and Large Scale Integration of wind power the case of inner mongolia in china
Applied Energy, 2013Co-Authors: Weihao Hu, Henrik Lund, Zhe ChenAbstract:Renewable energy is one of the possible solutions when addressing climate change. Today, Large-Scale renewable energy Integration needs to include the experience to balance the discrepancy between electricity demand and supply. The electrification of transportation may have the potential to deal with this imbalance and to reduce its high dependence on oil production. For this reason, it is interesting to analyse the extent to which transport electrification can further the renewable energy Integration. This paper quantifies this issue in Inner Mongolia, where the share of wind power in the electricity supply was 6.5% in 2009 and which has the plan to develop Large-Scale wind power. The results show that electric vehicles (EVs) have the ability to balance the electricity demand and supply and to further the wind power Integration. In the best case, the energy system with EV can increase wind power Integration by 8%. The application of EVs benefits from saving both energy system cost and fuel cost. However, the negative consequences of decreasing energy system efficiency and increasing the CO2 emission should be noted when applying the hydrogen fuel cell vehicle (HFCV). The results also indicate that developing renewable energy is crucial for transportation electrification.

Large Scale Integration of wind power into the existing chinese energy system
Energy, 2011Co-Authors: Henrik Lund, Brian Vad MathiesenAbstract:This paper presents the ability of the existing Chinese energy system to integrate wind power and explores how the Chinese energy system needs to prepare itself in order to integrate more fluctuating renewable energy in the future. With this purpose in mind, a model of the Chinese energy system has been constructed by using EnergyPLAN based on the year 2007, which has then been used for investigating three issues. Firstly, the accuracy of the model itself has been examined and then the maximum feasible wind power penetration in the existing energy system has been identified. Finally, barriers have been discussed and suggestions proposed for the Chinese energy system to integrate Large-Scale renewable energy in the future. It is concluded that the model constructed by the use of EnergyPLAN can accurately simulate the Chinese energy system. Based on current regulations to secure grid stability, the maximum feasible wind power penetration in the existing Chinese energy system is approximately 26% from both technical and economic points of view. A fuel efficiency decrease occurred when increasing wind power penetration in the system, due to its rigid power supply structure and the task of securing grid stability, was left primarily to Large coal-fired power plants. There are at least three possible solutions for the Chinese energy system to integrate Large-Scale fluctuating renewable energy in the long term: Redesigning the regulations to secure grid stability by means of diversifying the participants, such as including hydropower and CHP plants; integrating Large-Scale heat pumps combined with heat storage devices to satisfy district heat demands and developing electric vehicles to promote off peak electricity utilisation.

Large Scale Integration of optimal combinations of pv wind and wave power into the electricity supply
Renewable Energy, 2006Co-Authors: Henrik LundAbstract:Abstract This article presents the results of analyses of Large-Scale Integration of wind power, photo voltaic (PV) and wave power into a Danish reference energy system. The possibility of integrating Renewable Energy Sources (RES) into the electricity supply is expressed in terms of the ability to avoid excess electricity production. The different sources are analysed in the range of an electricity production from 0 to 100% of the electricity demand. The excess production is found from detailed energy system analyses on the computer model EnergyPLAN. The analyses have taken into account that certain ancillary services are needed in order to secure the electricity supply system. The idea is to benefit from the different patterns in the fluctuations of different renewable sources. And the purpose is to identify optimal mixtures from a technical point of view. The optimal mixture seems to be when onshore wind power produces approximately 50% of the total electricity production from RES. Meanwhile, the mixture between PV and wave power seems to depend on the total amount of electricity production from RES. When the total RES input is below 20% of demand, PV should cover 40% and wave power only 10%. When the total input is above 80% of demand, PV should cover 20% and wave power 30%. Meanwhile the combination of different sources is alone far from a solution to Large-Scale Integration of fluctuating resources. This measure is to be seen in combination with other measures such as investment in flexible energy supply and demand systems and the Integration of the transport sector.
