Optimization analysis of active distribution network operation considering grid reconstruction

Considering the influence of grid structure adjustment on system voltage and power transmission capacity, a stochastic optimization method for active distribution network operation is proposed, and the mathematical expression of topology reconstruction of distribution network is given. The stochastic uncertainty of renewable power generation power id described in the form of random scenes. The minimum operating cost of the distribution system is the goal. The electrical physical constraints and safe technical requirements that the distribution system needs to meet are taken as constraints. A stochastic optimization model of active distribution network considering grid reconfiguration is constructed, and the model is solved by firefly algorithm. The effectiveness of the network reconfiguration to participate in the methods of eliminating uncertainty is verified by a modified IEEE 33 distribution system.
