With the proposition to install a large number of phasor measurement units (PMUs) in the future power grid, it is essential to provide robust communications infrastructure for phasor data across the network. We make progress in this direction by devising a simple time division multiplexing scheme for transmitting phasor data from the PMUs to a central server. Time is divided into frames and the PMUs...
We consider fault detection through apparent changes in the bus susceptance parameters of modern power grids. We formulate the problem using a linear errors-invariables model and derive its corresponding generalized likelihood ratio (GLRT) based on the total least squares (TLS) methodology. Next, we propose a competing detection technique based on the recently proposed total maximum likelihood (TML)...
Using a linear DC power flow model, the power flow calculation can be determined by the bus susceptance matrix and the voltage angles. In this paper, we consider a power system where the voltage angle measurement at each bus is transmitted to a control center via a wireless communication channel. In order to model unsuccessful transmissions, we derive a two-component Gaussian mixture model to describe...
