Abstract The schema in the Relational Database Management Systems is used because of the unstructured data and the overhead of Extract, Transform and Load. Schema is important in the data analysis particularly in the tools such as Hadoop. Schema enables the loading of raw data and processing and ultimately help to interpret the data. Data sharing is important in the public... Read More


Use of Controllers for High Order Linear Models

Jordan Badev, Angel Lichev and Georgi Terziyski

https://doi.org/10.6025/jdp/2021/11/1/7-14

Abstract To locate and find the high order linear models, the method for organizing experiments and to collect the required data is important. We perform the experiment with the help of a controller in the closed loop. We have used the frequency characteristics for collecting the variables with the performing mode values.... Read More


Designing a Micro-grid to Optimize the Energy Storage Capacity using GridLab-D

Vassil Guliashki, Galia Marinova

https://doi.org/10.6025/jdp/2021/11/1/15-23

Abstract We in this work have designed a micro-grid to optimize the energy storage capacity. For this exercise we have used an open source tool called GridLab-D for simulation of micro-grid elements. We have use the Matlab environment to run the optimization solver. We have also deployed the GridMat as the interface between Matlab and GridLab- D. To run the experiment,... Read More
