摘要

This paper introduces a new method to analyze the connection of an intermittent generation unit to an active distribution network. This method permits the assessment of the voltage/current constraints that the unit might generate during its operation, and also the study of various smart solutions, alternative to grid reinforcement, like advanced voltage regulation schemes or generation curtailment. To do that, time series are used as inputs (for generation profiles, load profiles on the studied network, etc ...) but a clustering technique is employed to generate a limited number of equivalent scenarios in order to reduce the number of points for which a load flow is calculated. This clustering technique allows a significant reduction of the computation time, thus making it possible to simulate very effectively one or multiple years of operation of the distributed generation (DG) unit(s) in a network. These simulations give useful results such as critical yearly quantities (like for instance losses or energy curtailed) that can be used to perform a proper technical and economic analysis.
