On the use of information quality in stochastic networked control systems

Approximation of the Time Alignment Error for Measurements in Electricity Grids

“…The impact of timing in access to measurement information in distributed systems has earlier been analyzed in [6] and such analysis put into context of different electricity grid applications in [8], [9] and also in generalized networked control applications [10]. This paper instead focuses on the deviations of a measurand caused by time alignment deviations at the sensor.…”

Improving the reliability of information­control systems at power generation facilities based on the fractal­cluster theory

“…Authors of paper [8], when examining existing ICS for STC in APCS at power plants, typically employ the averaged, or root-mean-square, values for electrophysical characteristics of technological parameters (current, voltage). As a rule, they underlie the formation of informational signals about changes and deviations, registering only at specified time intervals with a delay (2 s), for the assigned setpoints interrogating every 0.5 s. Such an approach does not make it possible to timely detect the misinformation that leads to false triggering and failures [9].…”

Using Smart Meter measurements to manage accuracy of current calculations in LV feeders

“…Furthermore, not all customer connections may be measured and not necessarily all deployed measurement devices can provide data for a specific time interval of interest, e.g. due to bandwidth constraints of low-bandwidth communication networks, [1], [2] or for non-technical reasons [3]. Inaccuracies or missing data from customer connections limits or reduces the benefit of grid observability applications.…”
