Information reliability in smart grid scenario over imperfect communication networks using IEC-61850 MMS

Abstract

The trend of producing energy from Renewable Generation (ReGen) plants is greatly increasing. This leads to the objective of building future power generation system entirely based on renewable sources. Since the power output of ReGen plants, such as wind power plants (WPP), varies continuously and thereby the voltages in the distribution grid, an effective control system is required, to govern the production from all ReGen plants. For this, control messages must be exchanged between the grid assets with reliable information to achieve optimum efficiency. This raises a challenge to assess information reliability and evaluate the performance of a controller. Therefore, considering the dynamic nature of information, this paper analyzes the information reliability in terms of correct and timely delivery of message signals, for remote control of a WPP using IEC-61850 MMS in a smart grid scenario. Based on this measure, the quality of controller performance is also calculated over various imperfect network conditions.
