In the proposed scheme, the Phasor Measurement Units (PMUs) are optimized. With the optimized Phasor Measurement Unit implemented on network topology, Backup Protection Zone (BPZ) is formed which are the subspaces of the lines and buses. In the transmission network whenever faults occurs, the sum of zero/and positive sequence currents entering the faulted BPZ is determined. The faulted zone is detected in a short duration by the proposed scheme. Due to this, the effect of fault on the network is reduced. To show the effectiveness of the scheme, it is applied in the standard Western system coordinating council (WSCC)-9 bus power system using MATLAB.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131615401","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}

Variation in wind speeds affects the energy conversion to a great extent. For maximum energy conversion to occur, the generator speed must be controlled. Various types of symmetrical and unsymmetrical faults are induced in the system in which DFIG is connected and the response is analyzed. To protect the DFIG during such faults, crowbar implementation is done using fuzzy logic controller in MATLAB/SIMULINK environment. The voltage and current in the system considered during such faults is also measured.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130825804","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 Protection Coordination between the Distributed Generation (DG) and conventional power system is needed for reliable operation.

This paper evolves a protection scheme to refine the tripping behavior of relay and to ensure the protection coordination between conventional power system and wind power distributed generation system. The interconnected power system is considered with normal and fault condition (Line to Line Fault) and the faulted zone is detected based on the impedance calculation method. The interconnected power system with distance protection is manifested in the MATLAB R2014a/Simulink environment and simulation results are analyzed.

NMGs comprises of multiple Microgrids (MGs) are linked by a typical bus for supporting and interchanging the electric power with one other in this suggested configuration. It consists of normal and selfhealing mode. These NMGs contain a two layer cyber communication network for information exchange and coordinate the self-healing process. Each MG contain a lower layer and operation of each MG are scheduled by energy management system (EMS).A number of EMS are linked by the upper layer for global optimization and communication. The aim of the first (normal) mode of performance is to schedule the dispatchable distributed generators (DGs) and loads to minimizing the operating cost and to minimize the supply and demand imbalance of each MG. This scheme switches to self-healing (next) mode when a fault or deficiency in generation happens in any one MG. The intention of self-healing mode of operation is to support the faulted portion of the system by the local power production capabilities of other normally operating MGs in an optimal cost. A Differential Evolution (DE) Algorithm is utilized to share the portion of required power support to each MG in a scattered manner. The demanded power support will be provided by the resultant overall power output of NMGs. The efficiency of the scheduled methodology was demonstrated by the following test cases.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"41 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114479087","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}

Power Converter Unit (PCU) of the SMES system consists of a DC-DC converter and a three-phase voltage source converter along with a DC-link capacitor which couples both the converters. Particularly, the voltage across the DC-link capacitor is tightly regulated using a dynamic evolution based control strategy in the DC-DC converter. Consequently, the DC-link voltage is maintained almost constant with a voltage regulation of ± 5.26% during pulsed power load condition. Moreover, an effective pulsed power load compensation, and uniform voltage distribution across the SMES coil are achieved due to the precise solid-state control. Nevertheless, the performance of the proposed SMES system is conducted in the MATLAB software.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125337291","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}
