The conventional grid system the world has been using ever since its advent in 1890s, but this aging infrastructure of demand driven control structure, has made in way for more robust, fast, inter-connected and a smarter system with a cutting-edge technology called the Smart Grid. Smart grid uses a bidirectional communication model between the consumer and the utility service. The sensing along the communication line is what makes the grid system smart. Linking the smart grid with fog and cloud not only makes the process extra firm but also more secure and reliable. This paper presents a mechanism to reduce the response time in the smart grid architecture so as the system is more responsive. We have introduced a system which reduces the response time in grid system using fog computing. © 2019, Springer Nature Singapore Pte Ltd.
