An Algorithm for Calculating the Optimal Zoning Scheme Based on Artificial Neural Network

A mathematical model with the least tie lines between subsystems and the least supply complexity is proposed, aiming at the problem of black-start partition after large-scale power outage in power grid. The minimum topology matrix and partition state matrix are constructed to describe the mathematical model more clearly. The solution of the mathematical model is transformed into a 0-1 optimization problem. In the light of the current situation that most 0-1 optimization problems are NP hard problems, Hopfield neural network is proposed to solve it. In this paper, the energy function considering the objective function and constraints is established, and the solution method is given. IEEE-118 nodes verify the effectiveness of the method proposed in this paper.
