This paper shows that the power grid topology can be approximately estimated simply by observing multiple power injection measurement data and exhibits almost similar patterns and characteristics to the original topology. Power grid topology is essential for various aspects of smart grid monitoring and operations. Recent studies show that by using the grid topology, an
This document discusses smart grid technology. It defines smart grid as an electric grid that uses information and communication technology to gather data and act on information about supplier and consumer behavior. The key components of a smart grid are smart meters, phasor measurement, information transfer, and distributed generation.
Cyber attacks on a smart grid aiming at misleading the control center with incorrect topology information are considered, and an undetectable attack that requires the modification of only a few meter data is proposed. Cyber attacks on a smart grid aiming at misleading the control center with incorrect topology information are considered. In such

The coordinated topology attacks in smart grid, which combine a physical topology attack and a cyber-topology attack, are investigated and a deep-reinforcement-learning-based approach is proposed to determine the minimal attack resources. In this article, we investigate the coordinated topology attacks in smart grid, which combine a physical topology
• An Energy Services Interface (ESI), possibly the Smart Meter (SM) itself, acts as a gateway between utility and user domains, relaying, filtering or generating cross-do-main messages according to a control model. • Control is hierarchical, with messages being sent up or down the grid by the control devices in each section.
This paper proposes an efficient channel impulse response (CIR)-based technique to detect topology changes in the power grid. The features of the proposed approach include the following aspects: (i) it is a software-only solution, not requiring any intervention on the current smart grid architecture; (ii) topology changes can be detected via a simple distributed

Smart grid (SG) technology transforms the traditional power grid from a single-layer physical system to a cyber–physical network that includes a second layer of information. Collecting, transferring, and analyzing the huge amount of data that can be captured from different parameters in the network, together with the uncertainty that is caused by the distributed
The explanation of the smart grid is not essentially unique, as its visualization to the investors and the technological complications can be different . The US Department of Energy (DOE) has suggested the definition of smart grid as "Smart Grid is an automated broadly distributed energy delivery network".

The smart grid is a highly relevant application area for distributed algorithms. Many of these algorithms use a predefined topology to control the information exchange between the distributed entities. Consequently, this exchange topology has a strong impact on the performance of the distributed algorithm.
