Abstract
Advanced metering infrastructure (AMI) is the basic support platform for intelligent microgrid system, but exorbitant construction cost is main reason of restricting its popularization and application. Power line carrier communication (PLCC) network based on orthogonal frequency division multiplexing (OFDM) technology is an available network construction scheme which can give consideration to transmission rate, transmission reliability and system construction cost simultaneously. To improve reliability and real-time of the PLCC network, a dynamic topology analysis algorithm for effective communication links based on signal broadcasting and transmission matrix is presented, and an routing optimization method by minimizing number of relay hops based on an improved Dijkstra algorithm is proposed. Example analysis shows their effectiveness and advantages.
