This chapter compares the system explained throughout this book with other systems expressed in other research. ‘The Trend on the Smart Grid Systems in the Republic of Korea' shows a normal system in Smart Grid Test Bed in Jeju-island, and the author distinguishes this approach with that of a new proposed method using RUDP (Reliable User Datagram Protocol).

1. Introduction

The preceding research Figure 1 is ‘The Trend on the Smart Grid Systems in the Republic of Korea’, which describes a typical system selected at the Smart Grid Test Bed in Jeju-island.

This study in Figure 2 distinguishes itself from the preceding research by proposing the PLC communication system and presenting the benefits of using RUDP in the Transmission Layer.

Smart grid test bed (proposed method)


The preceding research (Yao, 2011) has been written as a graduate of Purdue University and the difference with this book is that it uses a different simulation tool. To be specific, while a DDoS detection system was simulated in the application of the precedent research, the same was tested by directly implementing it in the Application Layer used in this study.

The preceding research is a Paper published on Journal and has different test bed software and the range of implementation Figures 3-9 (Soetedjo, Lomi & Nakhoda, 2015).

Figure 3 describes the architecture of the power distribution network of proposed Smart Grid test bed. The network is comprised of three separate power resources such as PV generator, wind turbine and utility grid, two power demanders (Home-1 & Home-2) and five power switches. These are linked with 12V DC-bus. The power switch assumes the vital role of managing the flow of electricity and controlled by the micro-controller which acquires commands sent from the Smart Grid Center through wireless communications.

Figure 4 shows the architecture of information network within the test bed. The architecture includes five nodes and a single center linked through Xbee communications. The Xbee module is mounted on an embedded system utilizing the Arduino micro-controller. The Smart Grid Center uses the SCADA software which runs on PC. Embedded Xbee module-equipped system interfaces with PC to establish a connection with each node. Followings are the detailed description of the components being discussed in this section.

PV simulator including the simulation software and the adjustable power supply is described in Figure 5. This power supply controlled by the Arduino micro-controller correlates with the output of the model. For a simple implementation model, the micro-controller sets the position of servo motor mounted on the potentiometer of current-controlled power supply, and the current and voltage level measured by each exclusive sensor will be checked by the Arduino micro-controller who sends the data to the Smart Grid Center through Xbee module. Simultaneously, it controls the power switch(s) following the commands given by the center.

Designing a wind turbine simulator is similar to that of PV simulator but the difference can be found in software simulations. That is, the Simulink models the wind turbine generator, not the PV generator. Hardware interfacing is analogous to the PV simulator.
