Improper operation and late response of control and protective device lead to cascaded events which if not attended properly and timely than blackout condition may arise. The witnessing reports on the past decades blackouts reveal this unavoidable truth. Among the several natural causes, protection system failure is one of them. In the past fifty years, several major blackouts were mandatory and transparently reported to the public. These reports helped researchers in their research paper to study and suggest various solutions for aforementioned problem.

Managing EVs with vehicle-to-grid (V2G) scheme can help in softening electricity demand and making grid more reliable and economic. In this paper, plugged in EVs are managed to facilitate demand response (DR). The modeling of V2G network is performed based on the dynamical complex network methodology in which EVs are moving among different districts. It is clearly seen from the simulations that incoming EVs affect the DR stability as it carries new energy and storage facility into a district. The robustness of the technique is studied by varying the parameters such as rate of convergence and willingness to pay. Moreover, to further reduce the electricity price for the prosumers, peak clipping objective is introduced in the DR program. The main intension of the peak clipping objective is to control the charging/discharging of EVs during peak hours based on the available state-of-charge (SOC) of the fleets. Proposed DR program effectively reduces the electricity price during peak load hours and help EV owners maximize their profits.","PeriodicalId":385912,"journal":{"name":"2018 2nd International Conference on Power, Energy and Environment: Towards Smart Technology (ICEPE)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122135309","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}

It is mandatory to produce quality of power from solar systems by using efficient inverter control operation with robust and flexible control design. The objective of this paper is to present a comprehensive analysis on two adaptive current controllers used for inverter operation and compare their performances based on THD for the grid injected currents under system dynamics. These artificial intelligent adaptive controllers are driven by neural network concepts followed by reformed weight updation process which entirely helps in minimizing current harmonics generated due to the application of inverter units, non-linear loads or distorted grid.

Local defect resonance (LDR) is one of such method which is based on intensifying the vibrations at the contacting surfaces. This method is found to be very efficient in early detection of cracks or any flaws in the material. In the present work, nonlinear vibration response of a fibre metal laminate (FML) having a circular delamination is studied in order to determine its local defect resonance frequency. The concept of LDR has been provided analytically and is validated using linear steady state analysis of Glass Reinforced Aluminium (GLARE) model in ABAQUS 6.13 software. Moreover, the nonlinearities caused due to intermodulation and interaction terms are observed by performing explicit dynamic analysis at LDR, super harmonic and sub harmonic frequencies. The explicit dynamic analysis is performed by considering four different forcing frequencies in form of continuous periodic excitation. It was evident that the effect of these excitations can be seen from any point on the GLARE model, independent of its location. Subsequently, the proposed study is validated by considering two different locations of the delamination in the GLARE model. The results obtained from the present study will be of high importance in performing structural health monitoring and high resolution imaging of defects in fibre metal laminates.","PeriodicalId":385912,"journal":{"name":"2018 2nd International Conference on Power, Energy and Environment: Towards Smart Technology (ICEPE)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115307416","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 STA of SOSMC attenuate the chattering effect that predominates in the classical sliding mode controller. The efficacy of the controller is checked in both simulation as well experimentally. The simulation is carried out using MATLAB R2016. The experiment is carried out on a laboratory setup using QUARC software (for hardware interfacing) and MATLAB R2016.
