Show moreThe thesis focuses on the reconfiguration process of the electrical distribution system, which reduces the real power loss in the system through optimizing the topology of the distribution system. The model selected for the reconfiguration process of the distribution system is an MILP (mixed-integer linear programming). In addition, an adjusted MILP model with distributed generator. DG is formulated, in which the DG can follow the requirement of real operation in an active way. The major contribution of this thesis is to add the time-dimension and uncertainties. In addition, compared to other methods, the addition of other features into the MILP model can be done easily since the linking constraints can be added into the whole model in a simple way. Through the linking constraints, the reconfiguration of distribution system can transfer from a static model of one time spot with constant supply and demand data to the dynamic optimization-based model that can deal with the entire time horizon and the uncertainty at specific hour. It makes the model closer to the reality. Finally the numerical result is used to verify the concept proposed in this thesis. M.S. in Electrical Engineering, May 2015 Show less
