System state estimation relies heavily on the measurements. With the advance of sensing technology, the ability to measure is no longer a bottleneck in many systems, and more and more researchers now focus on the rich-information setting, i.e., big data. However, although information never hurts, it does not help unconditionally. How to make the most of it depends on whether we can process the data...
State estimation in smart grid highly relies on the availability of measurements. Due to the interconnected nature of the power grid, the measurements at different substations are not totally independent and thus contain some redundancy. Among the various environments the power grid work in, there are certain circumstances the system communication capability is limited such that transmitting a lot...
Distributed state estimation in smart grid highly relies on the availability of measurements. Transmitting a lot of measurements within a small time interval is costly and sometimes even impossible. This paper explores the problem of distributed state estimation in smart grid with constraint on the number of measurements that is able to be transmitted in one step. It is shown that there exists a lower...
