TL;DR: In this article, the authors define an algorithm that allows the requirements of both classes to be met simultaneously, thus avoiding an a priori selection of either the fast response time of class P or the accuracy of the class M. The validation of the solution, performed by means of simulations in all the static and dynamic conditions defined in the standard, confirms that the method is able to comply with all the limits indicated for both classes for synchrophasor and frequency measurement.

TL;DR: The impact of the phasor estimation models on the accuracy of these devices, focuses on algorithms proposed in the literature for the estimation of dynamic phasors, and studies their performances under several different conditions.

TL;DR: A new PMU-based iterative line parameter estimation algorithm for DNs, which includes in the estimation model systematic measurement errors, is presented, and exploits the simultaneous measurements given by PMUs on different nodes and branches of the network.

TL;DR: A novel adaptive distribution system state estimation (DSSE) solution that relies on distributed decision points and exploits the Cloud-based Internet of Things (IoT) paradigm is presented and discussed, which is adaptive in the use of updated accuracies for the measurement devices.

TL;DR: A new distributed architecture to measure synchrophasors in power substations, inspired by the standards IEC 61850 is proposed and suitably modified to have high performance also in terms of response time in presence of step change conditions.
