Validation of a State-Space Load Flow Simulation Depicting an Energy System with Sector-Coupling Technologies

This publication outlines the principles for carrying out load flow calculations using the mathematical state-space representation which are applied for modelling the loading behavior of a medium-sized German power grid. A method of verifying the results is presented which relies on a comparison of simulation results. Furthermore, the simulated load flows are analyzed by correlating each sub-grid’s simulation results with corresponding real, calibrated measurements. In this context, a feeder-specific scaling procedure is demonstrated, used for optimizing each feeder’s load profile.
