Abstract
The key to a Smart Grid is to manage electric power within the grid efficiently. There are many advantages in building a smart grid but it is useful in using it as an ancillary power grid for the business that can be damaged extensively due to blackout or interruption of power caused by hurricanes at power plants, substations and other related infrastructures. Fish farms in the republic of Korea use a considerable power and suffer a serious loss from a mass stranding caused by power interruptions. This chapter introduces a case study which aims to design a power line-based communication for the fish farms/vertical farms as the cost of constructing an internet network at the farm with UTP cables and other communication equipment is very high. This section includes a designing technique for the entire system and its necessary applications.
