Aggregators with smart communication facilitate the utilization of batteries of EVs as portable power plants for emergency and ancillary services as well as for daily load scheduling which helps to increase the reliability of the existing grid. But the penetration of such power sources from the distribution side should also ensure the stability of the existing power system. This paper investigates the voltage stability of a power system with participation of EVs in grid scheduling. A cost model of battery of EV to schedule the available active and reactive power is proposed. A hierarchical control strategy to aggregate the capacities of EV batteries is also proposed in this paper. Optimal scheduling of modified IEEE 9 bus test system is done in MATPOWER with EVs as virtual power plants (VPP). To evaluate the voltage stability of the system, L-indices of the load buses with and without the participation of EVs are determined using MATLAB.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125922758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is difficult to obtain the internal junction temperature of SiC modules in real time, limited by sensors and testing methods. The junction temperature estimation based on the thermal network model combined with an integrated negative thermal coefficient (NTC) thermistor is an effective evaluation method. The existing thermal network models omit effects of the solder layer fatigue aging due to thermal stress, resulting in junction temperature estimation error. In this paper, a junction temperature estimation method is proposed, which establish the relationship between NTC sensor temperature and the thermal resistances of chip solder layer and bottom layer. The junction temperature and NTC sensor temperature of the SiC module is expressed using the equation of state analysis to obtain a discrete-time system of temperature. The aging thermal resistance parameters of the thermal network model can be identified online, and the accurate online estimation of different aging conditions inside the module can be realized.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122433853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the increased demands and tasks placed on them in addition to academic labor reducing their valuable time. This results in work dissatisfaction and indignation among faculties. In order to increase satisfaction and better manage workloads, a number of colleges and academic institutions have used workload allocation models. From the list of subjects, the faculties provide the preferences of the choice of subjects. Each faculty must be allocated with fixed n umber of subjects. The allocation must happen in such a way that no faculty member remains unallocated and no subject remains without a faculty, given that each faculty member provides more than three preferences for a subject and more than two preferences for lab. At present, academic institutions follow a manual method of subject allocation to faculties. This work presents an optimal distribution of subjects to the faculties, considering the above-mentioned constraints in an automated and efficient manner.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129579435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among DNNs, Convolutional Neural Networks (CNNs) are generally used for image processing and video processing applications. In CNN, most of the computations are used up by convolution process. Winograd minimal filtering-based algorithm is one of the effective methods for computing convolution for small filter sizes. A prominant component of CNN accelerator design is the processing element (PE) unit which mainly comprises of the bulky multiply and accumulate (MAC) units and adder tree. It is the PE that performs the convolution operation. In this paper, new processing element has been designed using Modified Booth Encoding multiplier (MBE) and Wallace tree adders to reduce the amount of hardware resources and power consumption. This modified PE unit is implemented on an architecture known as UniWiG (Unified Winograd GEMM architecture). The proposed design reduces hardware complexity and achieves better power efficiency than the previous designs. Hardware realization of this work is done using Verilog Hardware Description Language(HDL) and tested on FPGA board.","PeriodicalId":407222,"journal":{"name":"2022 IEEE International Power and Renewable Energy Conference (IPRECON)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128264012","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
