Aimed at improving the resilience of distribution systems and analyzing the influence of uncertainties on the postdisaster emergency recovery process of a power-transportation system,this paper proposes a multi-time-step rolling optimization strategy based on model predictive control(MPC).First,the prediction models for three types of uncertainties:recovery time of faulty equipment,load demand and photovoltaic output are *** it is assumed that traffic flow and density can meet a specific relationship,the cell transmission model(CTM)can be used to establish the transportation *** evidence theory is used to model and analyze the two types of uncertain factors that constitute fault recovery time:travel time and repair ***,a mixed integer linear programming model of emergency recovery is established,in order to minimize load reduction and restoration resource scheduling *** variables include repair sequence of faulty equipment and the scheduling plan for restoration *** the rolling optimization and feedback correction process,load demand can track the expected value and economic loss of power outages can be reduced as much as ***,a case study is used to verify the effectiveness of the method proposed in this paper and validate a multi-time-step rolling optimization strategy has the advantages of updating uncertain information multiple times,which can achieve the goal of planning a shorter path for the repair crew and shortening the total duration of fault recovery。

Comparative Analysis of Noise Margin Between Pure SET-SET and Hybrid SET-PMOS Inverters

引用

Chinese Journal of Electronics 2025年第1期34卷 146-155页

作者： Fan Zhang Yi Liu Yibo wang Minghu Wu sheng Hu Youli Dong Hubei Key Laboratory for High-Efficiency Utilization of Solar Energy and Operation Control of Energy Storage System Hubei University of Technology School of Electrical and Electronic Engineering Hubei University of Technology

Single-electron transistor（SET） is considered as one of the promising candidates for future electronic devices due to its advantages of low power consumption and high integration. The comparative analysis of SET-based inverters, especially the noise margin, is carried out. Pure SET-SET and hybrid SET with p type metal oxide semiconductor（SET-PMOS） inverters are designed for investigation. The effects of SET supply voltage, junction resistance and junction capacitance on noise tolerance and power consumption of inverters are studied. For hybrid SET-PMOS inverters, the noise margin for a logic high（NMH） is less than 60 mV under various conditions, which may become the bottleneck of its application. For pure SET-SET inverters, both NMH and the noise margin for a logic low（NML） could reach 300 mV at a supply voltage of 0.8 V. The minimum power consumption of pure SET-SET and hybrid SET-PMOS inverters is 2.85 nW and 58 nW, respectively. The pure SET-SET inverters have greater noise tolerance and lower power consumption, which is more conducive to large-scale integration. When junction capacitance CJ= 0.0273 aF and junction resistance RT≥1 MΩ in SET-SET inverters at a supply voltage of 0.8 V, the NMH and NML are not significantly affected by the junction resistance and the noise margin fluctuates at 300 mV.
