Optimal reconfiguration of the active distribution network with distributed generation and electric vehicle

Abstract

It is a challenge to the stable operation of the active distribution network (ADN) with the distributed generation (DG) and electric vehicle (EV), and the reconfiguration is an important method to improve the stability of the system. The multi-objective reconfiguration model is established under the battery-swapping mode, the network loss and the voltage deviation index (VDI) are set up as the optimisation functions, and the number of switching operations is considered as the constraint. The global optimal position is updated through the niche technique; the optimal compromise solution is chose from the Pareto solutions using the fuzzy satisfaction evaluation decision method. Finally, the effects of different scenarios on the target value and the voltage of each node are compared and analysed from the simulation results in IEEE69 nodes system. The results show that the proposed method can effectively improve the stability of the system.
