Abstract: Simulation architecture of intelligent distribution network was investigated based on component service, Service Oriented Architecture computing framework, modules coordination mechanism and component deployment and realization method were proposed. And data interactive interface, transmission and integration method with online data resources were proposed. Meanwhile, distribution network simulation model, including photovoltaic, wind power and other distributed generation was established, which designed online power flow, fault calculation, reliability, reactive power optimization, distributed generation locating and sizing function module. An online simulation system of intelligent distribution network was realized on basis of the architecture and method above. Through a 10 kV distribution network example, feasibility of the simulation method proposed was verified.
