Orthogonalized correlation–distribution method for acquiring power offer and demand in energy informatics

Abstract

Groups of decentral power systems are usually managed in an integrated way to keep efforts reasonable. For fluctuating power offer and demand, i.e., their time series of monitoring data, a generic description is proposed based on decoupled modelling of correlation and distribution functions. Distributed monitoring databases together with standardized evaluation tools give a broad representation of operation experience for the variety of dispersed power supplies, e.g., by normalized yields of irradiation reference and load. They allow for supply quality management, system design, comparison and continuous improvements.
