A Review On Cyber Security Challenges In Smart Grid System

The Smart Grid is the innovativeness of the electricity system. A smart grid altercates from the conventional grid in that it readies two-way communication of electricity data, instead of one-way flow. Smart grids ratify real-time data collection niggling electricity supply and demand towards the transmission and distribution process, making monitoring, generation, consumption and maintenance more effective. The role of the grid is to provide omnipresent communication capability for collecting data from sensors and meters and provide congruent information to support multiple activities such as affirming grid stability, detecting and resolving aberrations, forecasting load, and overseeing demand response [7]. Although smart grid expresses various problems of the traditional grid, it faces a number of security confrontations like Physical attacks, cyber-attacks or natural disasters are major nameable form of threats to Smart Grid s deployment which could lead to infrastructural failure, blackouts, energy theft, customer privacy breach, endangered safety of operating personnel, etc. so in this paper we study on security challenges and solutions in Smart grid System.
