The EMI SE of epoxy-MWCNT nanocomposites, increases with increment in the wt% of pristine MWCNT nanofillers. No significant improvement in EMI SE of epoxy nanocomposites loaded with defect functionalized MWCNTs is noticed. Also, a substantial increment in EMI SE of epoxy-MWCNT nanocomposites, is noticed with increment in thickness up to 3mm.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126339280","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}

In unscheduled islanding, the solution must be obtained with minimum time and minimum load curtailment by maintaining all the system parameter constraints intact. First, the unscheduled intentional islanding is formulated as a nonlinear constrained optimization problem. Then, the TRSLP based optimization method is employed to obtain the final switching sequence of the network so that intentional islanding can be done in optimal manner. The objective function of the optimization problem is to minimize the amount of load curtailment. To validate the proposed technique, a 7-bus microgrid test system is simulated in Real-Time Digital Simulator (RTDS) and corresponding system parameters are further used in the TRSLP optimization technique to get the optimal islanding area.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122277171","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}

To improve it Virtual Synchronous Generator (VSG) concept was developed. The objective of the method was to improve the frequency response of a system following a sudden disturbance. Though these traditional control strategies are successful in providing primary frequency response (PFR) and inertial response (IR), the frequency restoration process is overlooked. The proposed method introduces two PI controllers in the active power-frequency loop of VSG by which the system frequency returns attains the nominal value in a quick time after the disturbance. The process is called secondary frequency regulation (SFR) and the proposed controller is called modified VSG as it uses the same set of control models as used in VSG. This work focuses on the comparison of traditional and proposed controllers in providing the three responses namely IR, PFR, and SFR. The controller performance is validated using MATLAB Simulation.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127713339","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}

For an EV charging system based on solar array, a fractional Lagrange filter is utilized here, thereby, improving the power quality of the distribution network. Furthermore, in order to guarantee an improved power quality (PQ), the grid currents are analyzed in covenant with the IEEE-519 standard.

This has raised the need of having a distribution system operator (DSO) that encourages the participation of DERs in the energy market. However, there could be a disagreement in the primary objectives of each DSO with the transmission system operator's (TSO's) objective. Thus, there will be a shortfall of cooperation across the system. Moreover, if TSO has direct control of DERs, then a huge computational burden will get introduced at the transmission level. Hence, the coordination between TSO and DSOs is required to take advantage of the resources available in DS at the transmission level. In this paper, a coordinated energy market framework is presented that involves the exchange of limited information at the common bus of connection. This will allow the efficient and economical utilization of cheaper and greener resources available in DS for the entire transmission & distribution (T&D) network without adding much communication burden and complexity. The proposed framework is implemented on an integrated T&D test system to validate its efficacy.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124963718","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 aim of this paper is to present a new approach for optimal placement of capacitor bank (CB), to minimize system loss and maximize the net saving for UDS. Particle Swarm Optimization is used to determine the optimal size of CB. The objective function for optimal sizing of CB consists of three terms - cost associated with CB purchase and installation, and cost of energy loss. The proposed method was tested on benchmark networks (IEEE 13-bus, and 25 bus systems) and compared with power loss index (PLI) based method. The results obtained from both methods are comparatively analysed and discussed. The comparison of power loss reduction, status of voltage profile, and net saving are presented for both approaches for the test systems.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130165851","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 Indian Power Grid is being monitored by a multi-level integrated Supervisory Control & Data Acquisition (SCADA)/ Energy Management System (EMS) installed at many control centres (or Load Despatch Centres) dispersed all over India. The Load Despatch Centres acquire real-time data from the substations as well from the other control centres and this critical power system operational data is transferred through a dedicated and secure communication system backbone network spread across the country. Keeping in view the importance of the communication system in a vast meshed network at the National, Regional and State level in India, the regulatory body of power sector i.e. Central Electricity Regulatory Commission (CERC) has also specified the regulations regarding Communication System for inter-State transmission of electricity. Apart from the conventional communication systems such as PLCC, Optical-fiber, etc., the VSAT communication is also making its place as a communication medium due to the various advantages it offers. The VSAT bandwidth connectivity charges have fallen in the past few years making it viable for being used in the power sector for the utilities. Hence, by adopting a reliable and easy-to-install communication technology such as VSAT will remove the communication related issues which is one of the major hurdles resulting in non-availability of real-time data to the Load Despatchers. Certain pilot projects had been done in North-Eastern Region with satisfactory performance for real-time data transfer. It was proven that the VSAT communication was able to cater the real-time operational data transfer requirements with an overall availability of more than 99% (excl. some minor technical issues) even in bad weather conditions. This paper deliberates the various key benefits and architectures of using VSAT communication in power sector of India.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"341 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131073124","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}

Limited research work is reported on control algorithm for battery and ultracapacitor as hybrid energy storage systems (HESS) in electric vehicle. Here, different energy management strategy is studied and presented. Conventional rule-based strategy is studied and simulated on Simulink platform.
