Abstract: A cyber-physical power system (CPPS), as the main energy source for other infrastructure, stands central and is essential to the operation of all other systems. In practice, various technologies are used to generate electricity, the combination of which is often referred to as the “plant mix.” The utility is constantly investigating other forms of energy and renewable energy sources that could be used to expand its current plant mix and has initiated various research projects looking at wind, solar, tidal, wave, and biomass sources of energy. Nevertheless, with the rapid expansion of a country’s power plant mix, the security of the CPPS (on both the cyber and the physical side) has become a crucial issue confronting practitioners. In this chapter, a knowledge-based representation, which is based on the purpose-function-working space-structure-behavior (PFWSB) paradigm, is adopted for designing a cloud-facilitated intelligent embedded system, which can be used for inpipe security inspection. Since most of the cyber-physical system (CPS) security studies are mainly focused on the cyberside, the purpose of this study is to fill such a gap by adding the physical security issue. At the conclusion of this work, we outline the technical challenges in the PFWSB framework and provide some recommendations for future work.
