The polynomial pattern recognition analyses enables the computation of winding responses (transient signal) measured at neutral terminal of the transformer winding due to impulse voltage excitation. Initially, simple polynomial analysis is performed through residual graph, mean square error to visualize the correlation between the transient signals. The polynomial analysis is further extended for identification of type of relationship between the transient signals. Further, polynomial approach is utilized through Akaike's information criterion to estimate the degree of association between the responses. It is a reliable additional tool which can be used to conclude if a winding insulation of transformer has withstood the rated lightning impulse test voltage or not. To prove the proposed analyses for lighting impulse test 66.7 MVA (138/69/13.8 kV) and 250 MVA (500/275/33 kV) are considered.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131100662","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}

Restructuring of energy sector is considered as a key initiative to obtain consumer benefits and social welfare. A power generating company has opportunity to maximize their profit in electricity market through selling the energy in competitive prices under incomplete information of other competing generators. In a day-ahead energy market, generating company (GENCO) sell the energy at optimal bid prices. In this paper the problem of finding market clearing price (MCP), load dispatch (LD) and bid cost under three different capacity and price blocks is carried out by oppositional theory enabled grey wolf Optimizer (OGWO) algorithm. Normal probability distribution function is used to model the rival behaviors. The bidding strategy of a generator for each trading period in a day-ahead market is formulated as a stochastic optimization and the same is solved through Monte Carlo method. The OGWO encompasses opposition concept with the grey wolf optimizer (GWO) algorithm to accelerate the convergence rate. The approach is tested over a dynamically changing electricity market. The results are compared with other techniques namely PSO and GWO. The OGWO shows competitive results.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126514924","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, a method is presented for the effective epilepsy region localization by analyzing electroencephalogram signals based on signal domain features. Features such as average signal energy and average log-energy entropy are extracted from signals and their differential signals in the signal domain. The experimental results show the ability of the proposed features to localize the epileptic regions by classifying the epileptic signals from non epileptic signals.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134114861","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 increasing use of electrical vehicles (EVs) and hybrid EVs raises the need of more charging stations. Increase in number of charging stations increases the power demand to high rate. This causes an extra burden on main supporting grid. And most importantly increases the load fluctuations on to the main distribution grid. In this novel control scheme, the different charging stations takes the constant power from grid throughout its operation and acts like constant load. The two layer control scheme is used to improve reliability of overall system in case of grid or any other charging stations failure. The charging stations consist of renewable sources like photovoltaic, wind, etc which helps in reducing green house gases as well as the operational cost of charging station. The simulation studies are carried out for proposed control algorithm in MATLAB Simulink environment and in real time simulator (OPAL-RT).","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115443297","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}

These ESDs are interfaced to the DC grid using bidirectional DC-DC converters. In an urban environment, where space is critical, a converter having small footprint is preferred. This necessitates a high switching frequency operation, which, in turn, increases the switching losses. To operate the converter at a high switching frequency while having low switching loss, soft switching is desired. For IGBT based converters, Zero Current Switching is the preferred mode for soft switching. In this paper, a zero current switching non isolated bidirectional converter employing two auxiliary switches for soft switching of the two main devices that form the power circuit of the bidirectional buck-boost converter has been proposed. The current stress on the main switches is only slightly increased as compared to a conventional bidirectional converter buck-boost converter. Simulation results are presented for the converter connecting two voltage sources while transferring power in either direction.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114503215","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}

{"title":"Acoustic emission techniques for transformers during lightning impulse voltage excitation","authors":"Jeyabalan Velandy, Satish Sundaresan","doi":"10.1109/PICC.2018.8384815","DOIUrl":"https://doi.org/10.1109/PICC.2018.8384815","url":null,"abstract":"Location of partial discharge (PD) is essential for transformer manufacturer to assess the dielectric integrity of the winding insulation during lightning impulse (LI) test in order to reduce the time and manpower utilization for diagnostics purpose at manufacturing place. As per international standards, there is a requirement of PD free behavior during impulse voltage excitation. Though, electrical methods are more sensitive for identification of PD, it is difficult to locate the location of the PD source accurately. Hence, with the increasing the use of Acoustic Emission (AE) techniques for acquisition of PD signal through acoustic sensor during power frequency voltage excitation, it would be instructive to provide the location of PD during impulse voltage excitation. Hence, the usefulness of AE technique is effectively adopted in this paper for location of the PD source during impulse voltage excitation. To study the impulse PD responses through AE techniques at different locations within the transformer, a PD source model is used to create the PD. The single and multi layer winding arrangements are also considered over the PD source model to analyze the AE signal propagation from PD source location to surface of the tank wall during impulse voltage excitations. The maximum cumulative energy criterion and variable S method are compared to estimate the relative time arrival of sensors responses. To avoid the convergence issues, non-iterative method is adopted for location of PD source accurately and it is compared with iterative method. 315 MVA, 400/220 kV auto transformer is utilized for validation of AE technique in order to declare whether the transformer has withstood the impulse test voltage or not. AE technique is verified with electrical method for detection purpose.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123582005","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}

Therefor for fair allocation of active losses in radial distribution network (RDN), a new strategy has been proposed in the paper. The proposed method is based on the current summation algorithm and adopted a branch-oriented approach. It also develops a relationship between current injected at a node and feeder power loss. Allocation of cross-terms of consumer/generator current is calculated using quadratic relation between power flows and losses. The advantage of the proposed method is that it does not consider any approximation to allocate the losses.

Cuk converter with inductors on both input and output sides reduces ripple on currents and improves the quality of source current. A Traditional Cuk Converter (TCC) is simulated and validated experimentally. But sharing of currents in inductors reduces ripples on source current further and also reduces peak current of the switch, improve the quality of input power of converters. Hence an Interleaved Cuk Converter (ICC) is proposed in this paper to share the source current in input inductors and to trim down the switch peak current hence to shrink ripples on source current. A Phase Shifted PWM (PSPWM) scheme is used in ICC and the switches are operated below 50% duty ratio to cancel the ripples on source and output sides. From the simulation and experimental results of TCC and ICC, it is observed that ICC reduces peak current of the switch, hence device rating and also delivers output power with better efficiency & improved transient performance. A modification on proposed ICC also provides boost operation with reduction in peak current of the switch.","PeriodicalId":103331,"journal":{"name":"2018 International Conference on Power, Instrumentation, Control and Computing (PICC)","volume":"146 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123375784","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}

Vector control scheme is being used in synchronously rotating reference frame for Rotor side converter (RSC) and Load side converter (LSC) does not require any special control scheme resulting in the lesser complex control circuitry. Reactive power demand for critical, non-critical loads and induction machine will be supplied from DC link capacitor.
