Abstract: Embodiments of the present disclosure relate to a time-skew correction unit and a method thereof. The time-skew correction unit classifies the electric grid into plurality of regions with one or more generators in said plurality of regions and obtains response time of one or more generators corresponding to each of the plurality of regions from a simulator. The time-skew correction unit further monitors the plurality of regions in real-time for predefined value of change of load data from one or more loads in the electric grid and determines time-skew offset for each of the plurality of regions based on the response time of the one or more generator and corresponding real-time data from the plurality of regions. Further, time-stamp of the real-time data from each of the plurality of regions is adjusted based on the time skew offset of corresponding plurality of regions for time-skew correction in the electric grid.
