摘要：
DC Micro-grid stability controller (SC) which is connected with storage plays an important role in DC micro-grid. However, the converter losses will be increased when the load is light under the condition of island operation while multi SCs are parallel operating. In order to increase the efficiency when multi SCs parallel operating, the optimization scheme based on the autonomous decentralized system was proposed. Every SC can receive the other SCs information by logical operation iterative algorithm, thus binding local voltage detection the quantity and droop characteristic of operating SC can be real time regulated. Ensuring micro-grid steady operation under the condition of grid connected and the condition of island, all the running SCs efficiency will approximate to maximum and the globe efficiency optimization can be realized. Based on optimizing, every SC can self adaptively regulate its droop characteristic, and the optimization effect will be more obvious as the load decreases. © 2016 Chin. Soc. for Elec. Eng.
