Optimal Scheduling of Reconfigurable Micro-grid in Normal and Emergency Conditions

Dou to penetration of stochastic resources in the microgrids, the need for new control and scheduling method is essential. Reconfiguration strategy can be considered as a practical solution for network performance improvement. Therefore, in this paper the scheduling of reconfigurable microgrid (RMG) in the normal and emergency conditions are analyzed. It is assumed that microgrid consists of several small neighboring microgrids, so in addition to the microgrid scheduling in the normal condition, the problem of neighboring microgrid management will be solved in the emergency condition. In the first condition, microgrid total cost minimization is considered as an objective while in the emergency condition, the microgrid divided to several neighboring microgrids and the proposed method tries to find the optimal structure for neighboring connection and minimizes the total load shedding, until the return to the normal condition. The results show the effectiveness of proposed method from the cost and load shedding minimization point of view.
