A Micro-grid Control System Based on EtherCAT
In micro-grid control system, control strategies and communication which can directly influence the speed and reliability performance of the system are the two main problems which need to be considered. In order to improve these performances, this paper presents a new structure which classified the components into levers according to their characteristics. This lever structure makes the system very clear, which is very helpful for making right control strategies. More importantly, an excellent communication protocol Ether CAT which is well known for its capability of speed is adopted to transform data in this paper. Finally, a contrast experiment exactly proved that Ether CAT is greatly improved the communication speed in this lever structure micro-grid control system.
