An electric power system includes an OLTC transformer including a plurality of primary and secondary windings inductively coupled to each other. The electric power system includes at least one on-load tap changer coupled to at least one of the primary and secondary windings that is selectively configurable to regulate the portion of the primary and secondary windings inductively coupled to each other. The electric power system also includes a plurality of buses coupled to the transformer and are positioned downstream therefrom. The electric power system further includes at least one processor coupled to the tap changer configured to regulate a voltage bandwidth of the tap changer as a function of estimated voltage values of at least one bus as estimated based on a priori values of power/current transmitted through each bus. The a priori values are substantially based on measured power/current transmission through the on-load tap changer.

System and method for regulation of voltage on an electric power system

A physical effect (optical effect), which may be observed in solar irradiance as shading due to a cloud passing overhead may be approaching a given location (e.g., a location at or proximate a solar power generator), has been discovered. This optical effect takes place prior to an occurrence of a solar obscuration event by the cloud, and thus this optical effect may be effectively sensed and processed in apparatuses, systems and methods to predict the occurrence of a solar obscuration of the power generator.

Prediction of solar obscuration events based on detection of spectral distribution shifts caused by approaching clouds

A prediction system for predicting solar irradiance based on cloud characteristics includes a sky imager that includes a customized lens configured to capture one or more substantially planar images of the sky. The prediction system further includes an image processor coupled to the sky imager and configured to process the one or more substantially planar images. Moreover, the prediction system includes a computing system coupled to the image processor and configured to detect cloud characteristics based on the one or more substantially planar images, and predict the solar irradiance based on the cloud characteristics.
