In recent times, the power grids are being challenged with different problems of power quality and voltage fluctuations, which are occurred due to large-scale Renewable Energy Sources (RES) integration with the complex grid network and load demand variations. In concern with this monitoring and control of the grid, state operation is very crucial. Smart grid security is provided with electronics control because energy demand increases daily, and electronics cost increases daily. It will cause an electricity burden on the government due to the significant electricity demand. Development of new energy sources is required with S.G. development for electricity demand fulfillment. After a few years of engineering ideas, the smart grid system developed the energy & fulfilling the demand.In this paper we have performed the Matlab simulation to analyse the performance comparison of different SE techniques for SG security analysis.
