The scheme uses the two-step droop control of smart inverters as well as scheduling of slow response capacitor banks and transformer tap changers. The peak shaving objective is also combined with the Volt/VAR support model to reduce dependency on traditional voltage regulators while minimizing operating costs. The problem is formulated as two-stage stochastic programming subject to day-ahead Volt/VAR device technical constraints. The results are used in a short-time probabilistic model for voltage deviation minimization by sub-hourly updating the forecasting signals. Finally, the competence of the proposed Volt/VAR support framework enabling the utilities to optimize the characteristic of inverters effectively and use the advantages of demand response (DR) and legacy devices is verified on three-phase distribution feeders. The results show that the proposed method leads to less voltage deviation and loss minimization compared to traditional strategies.","PeriodicalId":183284,"journal":{"name":"2023 IEEE Texas Power and Energy Conference (TPEC)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127504011","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}

The physical layer usually consists of the power grid and protection devices whereas the cyber layer consists of communication, and computation and control components. Combining components of the cyber layer in one layer complicates the process of modeling intra-actions because each component has different failure modes. On the other hand, dividing the cyber layers into a large number of sub-layers may unnecessarily increase the number of system states and increase the computational burden. In this paper, we classify system layers based on their common, coupled, and shared functions. Also, interactions between the classified layers are identified, characterized, and clustered based on their impact on the system. Furthermore, based on the overall function of each layer and types of its components, intra-actions within layers are characterized. The strategies developed in this paper for comprehensive classification of system layers and characterization of their inter- and intra-actions contribute toward the goal of accurate and detailed modeling of state transition and failure and attack propagation in CPPS, which can be used for various reliability assessment studies.","PeriodicalId":183284,"journal":{"name":"2023 IEEE Texas Power and Energy Conference (TPEC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129556468","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}

Induction motors are durable and inexpensive, so they are used in many industrial fields, from small-capacity to large-capacity pumps and fans over 100kW. Conventional V/f scalar control is widely used in induction motor control because it is easy to use. However, since open-loop control is without a feedback component, the speed decreases due to slip as the load increases. In addition, performance deteriorates in the low-speed region due to the influence of stator resistance and slip. Furthermore, there is a disadvantage in that the loss is more significant at light loads. Therefore, this paper proposes a novel method to combine V/f patterns and compensate for V/f control with speed and torque estimated through a nonlinear speed observer and a magnetic flux observer. In considering the nonlinear dynamic characteristics of the induction motor, the gains of the nonlinear speed observer are selected as multiple points. Using a 75kW induction motor simulation and MATLAB/SIMULINK, we verified that the nonlinear speed observer could accurately estimate the actual speed. In addition, it confirmed that the hybrid V/f control performance was improved by compensating the estimated torque obtained by the magnetic flux observer to the V/f control.","PeriodicalId":183284,"journal":{"name":"2023 IEEE Texas Power and Energy Conference (TPEC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131619540","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}

These tools can help improve grid reliability and ensure optimal grid operation. Several distribution system closed-loop controllers with applications such as Integrated Volt/Var control rely on power flow results to make grid optimization decisions. Hence, the accuracy of the power flow results is of paramount importance for appropriate informed decision-making. This paper presents an analysis of the Distribution Management System (DMS) power flow performance, including a selection of appropriate performance metrics. The selected performance metrics are used to detect and analyze inaccuracies in DMS power flow results. The investigation is carried out on near-real-time power flow results from multiple substations obtained from a utility company. The substation models and SCADA measurements were also used in the analysis. It is envisioned that this power flow performance analysis can help guide further studies to identify causes of poor power flow performance and mitigate them.","PeriodicalId":183284,"journal":{"name":"2023 IEEE Texas Power and Energy Conference (TPEC)","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132708101","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}

Multilevel inverter-based drives have become crucial for medium and high-power applications of Brushless DC motor drives. However, a Brushless DC(BLDC) motor suffers from the severe drawback of commutation torque ripples, mainly due to the inductive nature of the stator. Nevertheless, with a three-level inverter to a BLDC motor, a significant torque ripple reduction can be observed compared to a conventional two-level BLDC drive. In addition, the good dynamic performance of hysteresis controllers makes them reliable for the current control. However, the major demerit is that it gives a variable switching frequency and asymmetrical switching pulses, which could amplify the torque ripples. An interleaving constant switching frequency-based current controller is proposed in this work, which divides the error into multiple bands. The error is compared to an interleaving carrier frequency-based comparator to produce the switching signal for the given reference torque. The proposed controller remarkably improves the performance of the BLOC drive in the low-speed region, and a significant reduction in torque ripple is obtained. The proposed method is implemented on the MATLAB Simulink platform, and the effectiveness is validated by the results presented.","PeriodicalId":183284,"journal":{"name":"2023 IEEE Texas Power and Energy Conference (TPEC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-02-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128875207","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}
