Sensors in the smart grid provide a way for utilities to obtain measurements that can be used to assess grid health. However, the vast majority of physical grid assets do not have sensors attached to them. For example, a utility may have hundreds of thousands of poles, many of which are part of an aging physical infrastructure. The utility, however, does have a wealth of information concerning pole...
Capital planning of a distribution electric power utility aims to improve the reliability of energy delivery to its customers. It is critical to prioritize capital investments on problematic feeders in a distribution network. SAIDI is one of the most commonly used key performance indicators of a utility. An optimal capital investment strategy should seek to maximize the intrinsic reliability of feeders...
.We describe a randomized algorithm that, given an integer a, produces a certificate that the integer is not a pure power of an integer in expected (log a)1+o(1) bit operations under the assumption of the Generalized Riemann Hypothesis. The certificate can then be verified in deterministic (log a)1+o(1) time. The certificate constitutes for each possible prime exponent p a prime number qp, such...
