Reconfiguration optimization of DC zonal distribution network of shipboard power system

摘要

The ability of reconfiguration is critical to the survivability and reliability of the shipboard power system. This paper presented a Mixed-Integer Nonlinear Programming optimization method to achieve the multiple objectives of reconfiguration, maximizing the restored load and minimizing the number of the switch operations. First, the shipboard DC zonal electrical distribution system (DC-ZEDS) is introduced, and a mathematical model is established to achieve the aforementioned objectives. Then, a typical DC ZEDS is token as an example, both line fault and generator fault are considered, the reconfiguration method is implemented by means of the GAMS platform, which proves the correctness and feasibility of the proposed method.
