Study of modeling and scheduling control of distributed generation on distribution automation system

An important feature of smart distribution different from traditional distribution network is to support a large number of distributed generation (DG) access. Modeling and scheduling control problems of DG need to be resolved on distribution automation system in the smart grid. In this paper, effect of DG on distribution network is analyzed first, and DG access requirements for distribution automation system are put forward. Considering the DG characteristics and scheduling control requirements for distribution automation system, DG modeling method and scheduling control function design are proposed on distribution automation system according to IEC 61968 modeling principles. Correctness of modeling method and feasibility of control principle are verified through using them in pilot project on OPEN-3200 distribution automation management system.
