Development of On-site Monitoring Terminal and Source-Load Coordination Strategy for Gridized Distribution Networks
With continuous diversification of source and load types,and increasingly complex structure of in distribution networks,how to quickly coordinate internal source-load power balance has become an urgent problem.First in-grid source and load compositions of gridized distribution networks were analyzed.Second a monitoring and communication scheme for collecting and communicating in-grid source-load information was studied from the perspectives of common in-formation and communication technologies.Then an on-site monitoring terminal was designed with functions of both in-grid source-load information collection and inter-grid communicative source-load power balance coordination.Consequently a source-load information-based inter-grid power coordination strategy was proposed,and verified along with the designed terminal by experiment.The results indicated that the monitoring terminal and the embedded coordination strategy facili-tate quickly and accurately coordination and transfer of source-load power of distribution network grids,and have certain applicative value for ensuring distribution systems'overall reliable operation.
