Cyber physical system approach for design of power grids: A survey

Cyber physical systems (CPSs) refer to the class of systems which offer close integration of computation, networking, and physical processes. CPS approach to system design has been conventionally used in several domains, such as smart homes and health-care systems, however, its use in the design of power systems is relatively new. The unique features of CPSs are expected to greatly benefit the smart power grids of tomorrow. In this paper, we review several recent advancements made in the field of CPS approach in design and operation of power grids. We also discuss the application of CPSs in other domains to gain insights into the techniques and design approaches which could also be beneficial for power systems. We present a classification of research work and identify the challenges in wide-scale adoption of CPSs. This survey is intended to enable the researchers and power system operators to get insights into working of CPSs and understand their potential in transforming the future power grids.
