First

the application demands of two-way interactive service of power utilization are analyzed. Based on the concept of advanced metering infrastructure (AMI)

a framework for the data acquisition and control communication system of two-way interactive service is developed. Secondly

in order to adapt to the diversity of data acquisition devices in the personal area network (PAN)

a data aggregation unit (DAU) based on IEC 61850 communication model is designed. Thus

the stability

reliability and interoperability between two-way interactive service systems

as well as the two-way interactive service systems and two-way interactive service platforms of power utilization are improved. Finally

based on the IEC 61850 standards

taking the two-way interactive service of distributed power generation systems as an exemple

an information communication model for the monitor terminal of distributed power generation systems is given. With the model

the two-way interactive services of distributed power generation can be included in AMI to satisfy the need of flexible and interactive intelligent power utilization. This work is supported by State Grid Corporation of China
