Smart Grid Secure Data Transmission for High Voltage Grid

Smart grid is a new breakthrough in terms of transmission and distribution power lines from power plants. All communication data transmission that occurs on the smart grid is done digitally, making it easier for operators to control and monitor every transmission data as well as monitor any equipment connected to the smart grid. However, the use of digital technologies makes the security becomes an important aspect of any communication that occurs in a smart grid system. The security will focus on the delivery and transmission of data transmitted from the power plant to any existing substations, as well as data communication that occurs between substations and also inside the substation. Data communications between substations is a very critical thing, so need for security mechanisms are applied to that communication. The addition of security against any communication will affect the performance of the data transmission in smart grid. The implementation of IPSec is used as security protocols are applied to each gateway that resides on each substations. This is done so that any communication between substations can be done safely. It is also necessary that the exact configuration of the encryption and authentication algorithms used in the implementation of IPSec protocol could potentially provide the best performance. Implementation substation network design on smart grid and security of data transmission is done by simulation using OPNET modeler 14.5.
