摘要： Embodiments of the disclosure includes operating a power grid, including: generating, by a power management system of the power grid, a power grid resource allocation profile indicative of an operation of the power grid constrained by operational information of the power grid; generating a difference between a value of upper bounds from a plurality of obtained convergence paths and a value of lower bounds from the obtained convergence paths, the obtained convergence paths being based on a plurality of different initial conditions for the generated power grid resource allocation profile; and generating a resource allocation schedule for power grid resources operating within the power grid if the generated difference is smaller than a pre-determined threshold, the resource allocation schedule corresponding to a convergence path associated with the value of the upper bounds, the resource allocation schedule being configured to be received at the power grid resources.

摘要： Systems, methods, techniques and apparatuses of state estimation are disclosed. One exemplary embodiment is a method comprising determining, with a state estimator, a state estimate based on power grid data corresponding to characteristics of a power grid; calculating, with the state estimator, a gradient based on the state estimate; calculating, with the state estimator, a first gain matrix based on a Gauss-Newton method and a second gain matrix based on Newton's method; selecting, with the state estimator, either the first gain matrix or the second gain matrix for calculating a correction of the state estimate; calculating, with the state estimator, the correction of the state estimate; updating, with the state estimator, the state estimate; and determining, with the state estimator, whether the updated state estimate has converged.
