Mainly, this paper focuses on a shunt active power filter (SAPF) based power conditioning unit (PCU) for a superconducting magnetic energy storage (SMES) system for power quality improvement. The SMES coil is interfaced with the electric grid via its PCU for an efficient energy exchange. In this paper, the charging, discharging and storing characteristics of the SMES coil are investigated mathematically for a clear understanding. The DC-link voltage of the system is regulated to achieve a harmonic free source current, high-quality power flow in the grid, and to compensate unhealthy reactive power compensation. Further, an instantaneous symmetrical component theory (ISCT) based control technique is employed in the PCU of SMES system to fulfil the above-mentioned objectives. The DC-link voltage is regulated by discharging SMES coil energy very quickly so that the total power loss in the SMES system and detrimental stress on the system due to transients can be minimized. Moreover, MATLAB/Simulink environment is used for simulation activities.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"267 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":"115310118","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 the proposed control strategy water heater loads are considered to be non-critical in nature and are scheduled in an efficient way to achieve certain benefits like reduction of peak loading, power rampage and electricity bills paid by the consumers. The noncritical loads are operated in different power saving modes instead of curtailing them completely. The required level of power saving is directly decided by the users, which in turn results in utmost consumer satisfaction. The scheduling of water heater loads is performed using electric springs. Electric springs are connected in series to the water heaters and based on the power savings specified by the users the heating loads are operated in different power saving modes. The robustness of the proposed methodology is tested on a 14 bus micro grid system and the simulation studies are carried out in MATLAB","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"14 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":"116923952","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}

DC Microgrid protection is substantial in order to provide reliable and continuous power supply to the customers. The objective of this proposed work is to detect and locate the fault for fast restoration of the system to normal operation. The proposed protection scheme for DC Microgrid uses Intelligent Electronic Device for detecting and locating the fault. For accurate fault location, the Least Square based estimation technique is used to estimate the fault inductance from which the fault direction will be identified. The fault direction information from the ends of the line segment in the DC ring Microgrid is used to discriminate the internal and external faults. The proposed algorithm is analyzed with different fault conditions and locations in DC Ring Microgrid. The 350V DC Microgrid with ring configuration and its protection schemes are simulated using MATLAB/Simulink environment and the simulation results will be analyzed. The results obtained prove that the proposed method is essential in identifying fault in DC Microgrid and more effective even with high fault resistance values.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"147 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":"115185765","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}

AGC is a system, for adjusting the power output and change in frequency of a generator in the power plants, in response to changes in the sudden load. The controller aims to adjust the power output at the nominal values. Due to lack of control performance with nonlinearities in the conventional PID controller, in this work consider as an intelligent controller such as Fuzzy Logic Controller is proposed. Fuzzy logic controller is used to restore the frequency and tie line power to its nominal value with minimum computational effort in the shortest possible time as well as handling the system nonlinearities.

The voltage vector selection strategy is based on flux and torque response. A common strategy to control induction motor using DTC is through “Proportional– Integral (PI) speed controller as reference torque estimator” and “flux weakening controller as reference flux estimator This paper makes an attempt to replace the conventional reference flux estimator by an Adaptive Network Based Fuzzy Inference System (ANFIS). Also the PI controller used for estimating the reference torque is tuned using Genetic Algorithm (GA). The Proposed DTC system is tested for both load and source variations. To analyse the performance, the flux, torque and speed variations are measured using the performance indices like Integral Squared Error (ISE), Integral Time Absolute Error (ITAE) and Integral Time Squared Error (ITSE). The analysis proves that the proposed ANFIS based reference flux estimator and GA tuned PI controller provides better robustness and disturbance rejection ability.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"33 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":"132904609","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 this article the teaching learning based optimization (TLBO) technique variant bare bones TLBO has been applied for solving proposed problem with linear and non-linear constraints. Traditional TLBO has two phases. In first phase learners improve their knowledge by absorbing teacher’s knowledge and in second phase by sharing knowledge with themselves.
