The identification experiment involves the collection of data samples with the application of step input, which is popular due to its simplicity. The gain elimination method is employed to bring dead-time into the parameter vector. The model parameters are estimated using two stage identification approach, where the first stage is simple least square and the second stage is instrument variable. The over-parameterized information vectors are computed using filtered derivatives. Simulation experiments are performed on benchmark systems to validate and compare the efficacy of the proposed approach with sensor noise.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130132477","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 single-phase grid-tied PV inverters are widely used to connect the low power, roof-top, and residential photovoltaic systems to the grid and these are in the distribution side of the power system network. In grid-tied PV systems normally a transformer is employed to provide galvanic isolation between the input side and the output side with voltage level transformation. However, if we use a transformer the weight or size of the whole system increases, which is to be installed at the distribution side which makes the whole system size bigger. So, for PV systems it is better to use an inverter topologies that is without transformer. However, extra care must be taken while designing the transformerless inverters to avoid safety hazards like leakage and ground fault currents which will be discussed in this article.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117190941","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}

As a result, an ac/dc converting system will be placed at the system's front end to convert alternating current mains into direct current sources for system operation. Load-end characteristics of the system will increase the phase shift between the voltage and current of the input AC power source. This has a detrimental impact on the system's power quality indicators and causes instability. In an ac/dc converter that needs power quality improvement, a power factor corrector converter is required between the uncontrolled rectifier and the load. Different converter topologies have been investigated and compared in this paper. The self-PFC features of various converter topologies are examined.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127559429","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}

Digital images form a large chunk of this digital data. Therefore, techniques like digital image watermarking are used for assuring image security. In this paper application of DNN based compression algorithm is examined for implementation of color image tampering detection and self-recovery system. The DNN based image compression is used to compress the host images and multiple copies of compressed images are embedded in the host image for self-recovery. Due to the smaller size and better quality provided by DNN based compression algorithm, the watermarked images have high PSNR (peak signal to noise ratio). Similarly, the quality of recovered images is also high. The DNN based algorithm is analyzed for different images and tampering conditions. In the best-case scenario, the algorithm can recover the image from about 88% tampering.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117072306","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}

So, uncertainty should be considered while analyzing the performance of system. The uncertainty can be included by considering model as interval system. This study develops an interval model for Doha water treatment system. Firstly, interval model is obtained while considering finite range of uncertainty in transfer function. Then, order reduction method is applied to reduce the order of interval system. To derive the model, an objective function is designed which is a function of time moments and Markov parameters. The objective function minimization is obtained through grey wolf optimization (GWO) algorithm. The GWO is found to be very effective in exploring and exploiting the search space. Due to this, the GWO is considered for minimization of objective function in this study. The results obtained support the efficacy and effectiveness of GWO for minimization of objective function designed for model reduction of interval system of Doha treatment plant.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129651520","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}

So there is a need to correctly predict the load and make a proper plan to handle the situation. It can be expected that the power management structure can be used to improve the stability of power supply and demand. The proposed flow regulator is mainly based on the rules of demand supply modeling of energy. In order to manage energy, this paper provides a method for predicting future power use of residential structures. Load forecasting allows an electric powered application to make crucial choices on buying and producing electric power, load switching and infrastructure development. However, with the deregulation of the power, load forecasting is even extra crucial. Short time load forecasting (STLF) can assist to estimate load flows and to make choices which could save overloading. MATLAB Simulation for the purpose of forecasting, using Artificial Neural Network (ANN) is performed for the assessment of real and forecasted load. The predicted performance is calculated with root mean square error (RMSE) and mean absolute percentage error (MAPE) in this paper. At the end, the predicted performance is also compared with the regression methods using neural regression.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126265945","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 distributed generators (DGs) used in the microgrid are interconnected to the grid through power electronic converters which do not provide any mechanical inertia due to which the stability issues arise in the grid. This paper focuses on control techniques for grid-forming inverters in islanded mode. This paper proposes an adaptive virtual synchronous generator (VSG) control for the grid forming inverter, in which online control of moment of inertia and damping coefficient are exercised to improve the frequency response in the islanded operation of AC microgrid. A simple microgrid including, a three-phase inverter, in which the input is fed by a DC voltage, and coupled to the load via LC filter, is considered for the simulation study. Different loading scenarios are studied with loads of type constant impedance, constant power, non-linear and dynamic load. To check the efficacy of the proposed scheme, real-time simulation is executed through the TYPHOON HIL-402 device. The real-time simulation results demonstrate the superior performance of adaptive VSG control over the conventional VSG control and droop control techniques.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127636754","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}
