Apparatus and Method for Selective Delivery of Distributed Energy Resources Information from Multiple Slave Devices in Smart Grid Environment

摘要

In order to selectively transmit only the subscription-requested management information to the real-time distributed power management server after the master device establishes a connection with multiple slave devices, the distributed power management information of the slave devices is polled for master/slave communication in real time It is collected and temporarily stored in a hash table, which is a data memory, and when the data value of an item requested to be subscribed by the distributed power management server is changed, the data of the item temporarily stored from the hash table is read and converted into a data packet that can communicate with the distributed power management server to an apparatus and method of a distributed power information management system for real-time transmission.
