As an important component part of the smart grid,the distribution network however suffers relatively low level of automation.A distribution network advanced application software system is developed,whose architecture is described and the key technical challenges are analyzed according to the actual state of automation level,network operation and onsite demand. The algorithms and the features of the main functions of the system are presented,including three-phase modelling,three-phase state estimation, three-phase power flow, voltage/reactive power optimization, network reconfiguration, service restoration,security evaluation,etc.The strategies of integration with the geographic information system (GIS) platform and other systems are also briefly treated and illustrated with typical examples of engineering applications.
