Abstract

A method and system for power grid optimization control based on a linear time-varying model is provided. The system model is first estimated offline using historical data combined with a piecewise linear regression method that supports a vector regression model. For online applications, a time-varying linear model prediction control framework based on a piecewise linear model coordinates the optimization control of both fast and slow regulating devices in the power grid. This approach does not require precise system model parameters, instead learning the power grid model from historical data. The method optimizes voltage distribution, reduces operating costs, and addresses issues like bad data and collinearity in the historical data, improving the voltage quality and enabling optimal operation even with incomplete models.

Abstract

The present disclosure relates to a non-destructive in-situ measurement device and method based on Raman analysis. The device comprises: a laser light source that emits a laser beam; a focusing component that focuses the laser beam above a movable sample stage, with the focal plane of the focusing component positioned at an initial position. During measurement, the focal plane is controlled to move from the initial position to the surface, side, or bottom of the structure under test. The movable sample stage holds the sample to be measured and can move in a plane perpendicular and/or parallel to the optical axis. The axis of the structure under test is parallel to the optical axis and located within the laser beam's focal region. A detection module collects specific Raman scattering signals returned from the sample under test, and the structure's planar and three-dimensional parameters are determined based on the collected results.
