Transient analysis of the power network using complex models of WFs is normally difficult. This paper, thus, proposes a Doubly-Fed Induction Generators (DFIGs) based equivalent model of large WF with its parameters estimated by the Extended Kalman Filter (EKF) approach. The proposed equivalent model of the wind farm is obtained by representing the rotor circuit of the DFIG as a constant current source. Hence, no measurements are required on the rotor side. The small-signal stability analysis proves the adequacy of the proposed model. The results are demonstrated for a practical model of the HornsRev1 WF integrated to the IEEE 39-bus system, and dynamic simulations of the aggregated model are compared to the complete detailed model. The simulation results show the efficiency, accuracy, and fast steady-state and dynamic analyses with the proposed aggregated model.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"23 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":"122291739","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 primary idea of the work presented in this paper is to leverage the dynamic voltage support capability of the grid-connected energy storage units during voltage fault ride through conditions on the distribution network. Firstly, a detailed analysis about the role of energy storage units in providing dynamic voltage support for both low and high voltage disturbances is presented and the conditions for maximizing the voltage support are derived. Further, the dynamic voltage support oriented control strategy for the converters of the energy storage unit is presented in detail along with the state-of-charge management of the storage device. Finally, a simulation study considering a supercapacitor energy storage unit connected to the CIGRE European LV residential distribution test feeder is carried out using Matlab/Simulink to validate the proposed control strategy. The results assert the fact that the grid-connected energy storage units aid the network voltage during disturbances with the proposed control strategy within their design limits.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"108 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":"122298486","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}

Distributed generations now stand as a potential replacement to suffice for the vast spectrum of power requirements. As an efficient amalgamation of distributed resources, microgrids deliver dependable and cost-effective power. In the instances of faults being induced in the main grid, it becomes pertinent that the distribution system operates separated from grid generators, which results in the microgrid becoming islanded. Islanded microgrid, due to inverter-based sources, has a limitation of maximum 2 p.u fault current. These reduced fault currents along with alteration in their magnitude and direction, and transition between connected to grid and islanded operation, renders conventional schemes of protection ineffective. This paper addresses to various protection issues and protection schemes in a microgrid. The advantages and limitations of various protection schemes are also covered.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"23 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":"115260717","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 paper presents the optimized scheduling of the flexible energy resources under Real-Time Pricing (RTP). The objective of the optimization is to reduce the energy cost of the residential end-consumer, which includes an Electric Vehicle (EV) with a vehicle-to-grid facility enabled and three extra appliances, with the minimal possibility of compromise in comfort and levelized energy cost. The RTP price variation depends on the system condition, and the consumption of the end consumer under optimized scheduling depends upon the RTP. So indirectly, consumers participate in system stability and quality improvement by curtailing the load at a higher price and shifting it to a lower price. The scheduling problem is formulated as a non-linear optimization problem. The two cases viz optimization problem with and without the discomfort index and levelized cost of energy are presented through the simulation results in this paper.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"18 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":"128504014","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}

Solar Photovoltaic (PV) technology is considered to be the future of energy. Small-scale rooftop plants are favorable for the fulfillment of consumer demand and generating revenue from surplus energy. Traditional distribution systems face power quality issues as a result of rooftop solar plant integration. For distribution networks with high PV penetration, Local Voltage Rises and reverse power flow (RPF) are major concerns. In this work, the author has proposed a Phase Shifting Strategy (PSS) for mitigation of Local Voltage Rises and Reverse Power Flow. Under high PV penetration, the IEEE 906 Bus European LV Test feeder was investigated. Co-simulation using OPENDSS and MATLAB has been performed to validate PSS in solving Local Voltage Rise and minimizing Reverse Power Flow issues. The results show that the voltage profile of all the consumers is significantly improved with the PSS.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"34 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":"125749319","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}

Nonstandard time inverse overcurrent relay characteristics are further used for minimization of operating time of overcurrent relays in the distribution system where fault current contribution from the distributed energy resources (DER) is extremely weak. In practical, this fast optimized operating time of relay is very hard to realize in field. If this fast operating time is realized in field, then it may cause unwanted tripping of feeders during the network temporary faults. This article discusses a modified relay coordination algorithm in which, a lower limit is provided on the operating time of overcurrent relays to block their operation during the temporary fault periods. In addition to this contribution, the application of the customized time-inverse relay characteristics are also extended for maintaining the relay coordination in distribution system with integration of distributed energy resources.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"57 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":"128254824","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 use of IEC 61850 based Client-Server communication service and Publish-Subscribe communication-service, which include Generic Object Oriented Substation Events (GOOSE) and Sampled Values (SV) have aided in the deployment of a more communication-intensive architecture in substation when compared to a non-IEC 61850 based substation. Performance of Protection and Control Systems (PACS) is now additionally influenced by the communication system in a substation. The fault-clearance time in an IEC 61850 based substation now includes the operating time of the protection Intelligent Electronic Device (IED) relay and the communication delay between protection IED and a Switchgear Control Unit (SCU). This paper proposes a method to calculate communication latency in a complex IEC 61850 based substation. It is vital to determine communication latency for understanding the overall performance of PACS. Latency calculation is also essential to optimize PACS design to achieve the requirements of various applications. The communication latency calculation method proposed in this paper uses the Substation Configuration Description (SCD) file to accurately determine the communication path and data flow between a publisher and subscriber. The method also calculates the coincident messages or traffic in the communication path between publisher and subscriber, which aids in determining the latency accurately.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"28 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":"130420840","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}

Blackout is a phenomenon that occurs not because of a single cause, but due to multiple cascading disturbances. A critical review of such events can help in drawing preventive strategies and ensures readiness to mitigate the risk of blackouts. In this context, the work reviews the causes and severity of blackouts of various geographical locations in the past decade. An attempt has been made to summarize major blackouts and their effects. Some recommendations are also presented to provide strategies for grid protection and to mitigate the severity of blackouts. Further, an index to identify potential category of events that may cause a blackout in a geographical location is formulated.
