All aggregators engage in the congestion control technique that adopts a decomposition-based optimization method. As a result, as compared to the traditional approach of day-ahead dynamic tariff, this method gives more predictability and clarity. In DDT approach aggregators provide their complete accumulated demand response (DR) and must be consider it during the operation. The DSO estimates congestion in days ahead and releases the DDT before to the settlement of the day-ahead market, using iterative interactions between the DSO and aggregators congestion control framework. As a result, the aggregators optimize their energy purchase portfolio considering expected price and publicly available DDT. The Roy Billinton Test System (RBTS four-feeder)'s network is being employed to perform case studies to illustrate the efficiency of the established approach towards preventing distribution network congestion caused by EV charging. The case study results show that the DDT technique, when compared to alternative decomposition-based approaches such as the multiagent system method, may minimize total energy usage and power losses costs.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"27 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":"124902908","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 traditional time-frequency (TF) transforms always generate low-resolution Time-Frequency Responses (TFR). However, Synchrosqueezing transform is a reassignment method that provides a high-resolution time-frequency spectrum while being invertible. In this paper, the focus is put on the wavelet-based synchrosqueezed transform (SWT) that represents the joint application of time-frequency transformation and T-F enhancement. The transient events considered in this study, include single line-ground (L-G) fault, three-phase fault (dead short circuit), load switching, grid disconnection, and distributed generation (DG) switching. SWT is also compared with other time-frequency transforms, namely, continuous wavelet transform (CWT) and S-transform. SWT gives a more concentrated and sharp TFR which improves the readability of the spectrum. Secondly, the effectiveness of the synchrosqueezing wavelet transform (SWT) over other time-frequency transforms including continuous wavelet transform (CWT), S-transform is verified by computing Renyi entropy as a performance indicator.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"1 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":"130359474","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}

P-bus is a reactive power support bus that maintains specific voltage at a minimum voltage bus, i.e., PQV-bus. Optimal locations of multiple DGs are determined using sensitivity factors based on reducing power loss and improvement in voltages. The capacity of reactive power support, ratings of DGs, and switching configuration are optimized by employing the recently developed Jaya algorithm. DGs accommodation is followed in sequential and non-sequential approaches. Topology constraints of reconfiguration are validated utilizing a spanning tree concept from smart graph theory. The following constraints are applied to study the problem: voltage limits at buses, current-carrying limits of lines, radial configuration, and no isolated node in the network. The proposed method's applicability is demonstrated on IEEE 33 and 69 bus radial DNs. Numerical results illustrate the validity and efficacy of the suggested method in comparison with the other existing algorithms.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"25 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":"130564412","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 event of grid failure, back up power sources must support the network. Thus, optimal planning of distributed generations (DGs) in power distribution networks need to be done so that in addition to grid power support, ancilliary services such as minimized real power losses and voltage deviations are attained. In the present work, combined resilience evaluation and analytic operational enhancement strategy has been studied in a radial power distribution network. To achieve overall minimal power losses and better voltage control, the Marine Predator (MPA) meta-heuristic optimization technique is adopted. The MPA is utilised to discover the best DG location and size at the same time. The proposed method is applicable to both single and multiple DG unit sizing and siting. Furthermore, to calculate the best size of DG unit, the suggested method just requires the results of the base case load flow. The proposed approach is tested on a IEEE 33-bus radial distribution test system.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"27 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":"130574120","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 manuscript unifies the idea of transient event detection and localization with the analysis of the oscillation mode that accompanies these impulsive events. The paper employs Discrete wavelet transform (DWT) to segregate transient events from oscillatory behavior that follows these events. The paper also proposes a novel indicator for the classification of transient events based on the most affected signals in due course of the event. Empirical Mode decomposition (EMD) and Hilbert spectral analysis (HSA) are utilized on the PMU signals severely affected by the event and further examine the oscillatory modes succeeding the real-time events. Oscillatory modes deduced from the above adaptive transformations are further categorized into three frequency bands based on power system control applications, thus helping operators provide efficient control actions. The novel methodology discussed in the paper has been applied to the IEEE 39 bus system with a dataset generated using the RTDS power system simulator and GTNETx2 based PMUs.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"10 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":"121197095","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}
