Information Quality Aware Data Collection for Adaptive Monitoring of Distribution Grids

Abstract

Smart Grid systems not only transport electric energy but also information which will be active part of the electricity supply system. This has led to the introduction of intelligent components on all layers of the electrical grid in power generation, transmission, distribution and consumption units. For electric distribution systems, Information from Smart Meters can be utilized to monitor and control the state of the grid. Hence, it is indeed inherent that data from Smart Meters should be collected in a resilient, reliable, secure and timely manner fulfilling all the communication requirements and standards. This paper presents a proposal for smart data collection mechanisms to monitor electrical grids with adaptive smart metering infrastructures. A general overview of a platform is given for testing, evaluating and implementing mechanisms to adapt Smart Meter data aggregation. Three main aspects of adaptiveness of the system are studied, adaptiveness to smart metering application needs, adaptiveness to changing communication network dynamics and adaptiveness to security attacks. Execution of tests will be conducted in real field experimental set-up and in an advanced hardware in the loop test-bed with power and communication co-simulation for validation purposes.

Visualization Techniques for Electrical Grid Smart Metering Data: A Survey

“…The main source of data in a smart grid is the adaptive metering infrastructure (AMI), where a large number of smart meters are deployed at the user end side [5]. Mechanisms for collecting data from the smart meters are addressed in [6] for the real-time state estimation of the grid. They are advantageous because they can facilitate the power flow control and identify exceeding limits of current and voltages.…”

“…The delays involved in the delimitation of the real-time definition can be defined as the transmission and the processing delays, represented in Figure 2. The transmission delay (smart meter -database) is bound to the adaptive data collection mechanisms presented in [6]. The data processing delay (database -visualization) is the aspect to be analyzed in this research and it will be used for defining the use case related to the real-time display of information.…”
