“…A run/trip decision threshold can then be defined in a slip vs. acceleration space [16]. The concept is based on the assumption that when the DGs are grid-tied, the (stiff) utility system will force S k and A k to be near zero and the operating point is near the origin.…”

Detection and prevention of unintentional islands powered by distributed generators like photovoltaics remains a key concern of utility protection engineers, especially in highpenetration and grid-support environments. These evolving circumstances dictate that new island detection tools are needed. Synchrophasors are highly promising in this regard, but some in the community remain skeptical about them due to costs. This paper discusses synchrophasors, how they may be used to detect islands, their cost-reducing value-added features, and synchrophasor-based island detection methods.

As increasing numbers of photovoltaic (PV) systems are connected to utility systems, distribution engineers are becoming increasingly concerned about the risk of formation of unintentional islands. Utilities desire to keep their systems secure, while not imposing unreasonable burdens on users wishing to connect PV. However, utility experience with these systems is still relatively sparse, so distribution engineers often

“…A solution to power swing problem is addressed using PMU data in [10]. PMU data is also used in generator black start [10] islanding and anti-islanding conditions with Distributed Energy Resources (DER) [11], to measure transmission relay parameters [12] and in protective relaying applications [13]. A basic PMU can provide a minimum of 30 samples of data per second.…”

This paper presents a density based clustering (DBSCAN) technique to visualize and analyze the smart-grid data. The technique will aid in detecting bad-data, various fault types, deviation on frequency, voltage or current values for better situational awareness. Synchrophasors (or a PMU) is a sensor placed on a transmission line that tracks voltage, current, phase and frequency of the line. To improve situational awareness of the smart grid monitoring in real-time, the utility must monitor the phasor data measurement delivered by the sensors. Time-stamped synchronized measurements offer tremendous benefit for pre and post-event analysis. The paper uses data from openPDC framework to aid system operators in carrying various predictive analytics, decisions.
