The analysis of the information needed for the planning of active distribution system

As the increasing application of ICT technology in power system, the information available is getting more and more, which has provided a firm foundation and possibility to the implementation of Active Distribution System (ADS). The key challenges at the ADS planning is how to integration with the optimization operation of DER (generation (DG, RES), Electricity Energy storage (EES) and interactive load). The questions firstly is how to make use of the available information,secondly is which information is primary needed and have to be provided , and thirdly is how to coordinate the information resources. This paper presents an analysis of the information which is necessary to be used on the planning and optimization of passive distribution networks (PDNs),including existing information system and available information, then analyses the differences between PDN and ADS, lastly, presents a simplified the future information model for ADS planning.
