This task focuses on the data analytics and its applications in Smart Grid where communication protocols enable power system operators $($PSO$)$ to collect real$-$time$/$near real$-$time data from various assets within different sections of the power system network. As core of the report, you are supposed to describe the prospect of using data analysis techniques for improvement of power system operation at different levels of generation, transmission, distribution and revenues. Therefore, in this task certain functionalities and services associated with operation of smart grid have to be highlighted taking into account data analytics and optimal decision making within different sections in power system. The following aspects should be included as criteria for assessing the report $($assessment criteria$)$: $$ Utilizing data analytics $($opportunities and challenges$)$ Infrastructure, platforms and technologies $($enabling big data analytics$)$ Master of Engineering $($Electrical Systems$)4$ MEE$605\_$Assessment$3\_$PaperB$\_$v$1$ Functionalities and services within different levels $($Generation$,$ Transmission, Distribution, etc.$)$ Integration of the Distributed Energy Resources $($DERs
