In recent years, the growth of behind-the-meter distributed energy resources (DERs) and smart loads (e.g., air-conditioners, storage devices, electric vehicles) have brought distribution grids to the forefront of smart grid advancement [85].

Estimation of smart grid topology using SCADA measurements

Power grid topology is essential for various aspects of smart grid monitoring and operations. Recent studies show that by using the grid topology, an adversary can construct stealthy attacks that can cause significant disruption to power delivery and the critical infrastructure. This paper shows that the power grid topology can be approximately estimated simply by observing

From the grid to the smart grid, topologically

In its more visionary acceptation, the smart grid is a model of energy management in which the users are engaged in producing energy as well as consuming it, while having information systems fully aware of the energy demand-response of the network and of dynamically varying prices. What is the actual cost of adding an edge to the topology
