This proposed control technique is used for three-phase interleaved inverter based shunt active power filter (SAPF) to enhance the power quality in the electrical distribution system. The conventional voltage source inverters are being used as a SAPF, which severely suffering with shoot- through problem. This shoot-through problem creates electromagnetic interference (EMI), ringing, temperature rise, etc. These problems have been considered for the analysis purpose to design the interleaved inverter based SAPF. The proposed PTF is sensitive to detect the distortions in the supply voltage and extract the fundamental component of supply voltage from the distorted supply voltage without distortions and phase delay. The complete system is modelled using MATLABo/Simulink software to analyze the working with available, distorted and unbalanced supply voltage.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"24 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":"116998018","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 improvement in stability can be achieved through rapid temporary increase of generator excitation. In this method, the IEEE type 1 exciter is employed. A multi machine system with two generators and a load is modelled and then the frequency is analyzed before and after the fault condition.

A high value of droop coefficient causes low frequency power oscillations between sources.

The paper presents a novel method to damp out these power oscillations in microgrid and stabilize the grid with higher droop coefficients.

Even though wind power is abundant in nature only a few countries have shown interest to potentially utilize the wind power for electricity generation. India is one among the countries which utilize wind power potential for the purpose of electricity generation. This paper embarks upon some major possibilities in India for exploration on wind power employment in electricity generation. Furthermore, the survey also summarises advanced technology implemented, future opportunity, government initiatives, important achievements and guiding principle on wind power consumption.

Hence, Plug-in Hybrid Electric Vehicles (PHEVs) usage has become an alternative solution due to the depletion of resources and the increasing price of fossil fuels. In this work, the driving pattern of the vehicles is calculated using probability density function. A Fuzzy Logic based method is used to correlate the arrival and departure time of the vehicle with the daily mileage as they are independent in nature. The total operating cost minimization is the main objective of the work by adopting controlled charging strategy. The controlled charging strategy comprises of three different modes: charging, discharging and idle mode. Thus, the economic scheduling of PHEVs using the controlled charging strategy is implemented considering two different test cases namely residential and commercial area, each with a parking lot for charging the vehicles. Finally, the scheduling of PHEV is performed using MATLAB and the results of the two different cases were analyzed under different charging levels and three All Electric Range (AER)-30,40 and 60 ranges of PHEVs.","PeriodicalId":170822,"journal":{"name":"2018 National Power Engineering Conference (NPEC)","volume":"87 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":"134560289","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}

Switched Capacitor MLI (SCMLI) is an alternative inverter with reduced power supplies compared to conventional inverter. It has self-voltage balancing and boosting capability. In this paper, a new three phase SCMLI topology and its closed loop control using Model Predictive Control (MPC) for output load current is presented. The proposed MLI topology is modular in nature and number of source module can be increased for more levels of output voltage. The implementation ofMPC control ofthe proposed MLI has been discussed and it was observed that the output load current follows the reference input. Further, a comparison study is presented between the open loop Phase Disposition PWM (PDPWM) control and Model predictive control.

To enhance the output voltage levels, cascaded MLI structure using proposed basic SCMLI structure has been introduced. Further, the analysis has been carried out for cascaded SCMLI for the symmetric as well as asymmetric dc source configurations. In comparison with other topologies, the presented topology provides more output voltage levels using reduced components. In the comparison study, different aspects of the number of switches, dc power supplies, capacitors, diodes for producing specific output voltage levels are accounted. Further, the switching stress and Total Standing Voltage of the inverter has been determined and compared with that of other topologies.
