Optimization Decision-making Method for Looped Network Restoration to Eliminate Transmission Line Overload in Network Reconfiguration
摘要
Abstract
Power system restoration after blackout is a complex process.During the network reconfiguration process,transmission line overloads may possibly occur with gradual pickup of loads due to the weak structure of the restored network.In view of this problem,a looped network restoration strategy was proposed to eliminate the line overloads by restoring some unenergized lines in this paper.The looped network restoration strategy from a tree-type network to a looped network was analyzed first.Then,a mixed-integer nonlinear programming (MINLP) model considering AC power flow constraints was established.In order to improve the computational efficiency,a fast hierarchical optimization method for looped network decision-making was proposed,in which the original problem was decomposed into a master problem and two sub-problems solved iteratively.The master problem was defined as the looped network decision-making optimization problem with the DC power flow constraints.The sub-problems were defined as checking of the SPA constraint and AC power flow constraints to validate feasibility of the solutions of the master problem.The effectiveness of the proposed method was validated on the IEEE 39-bus and the IEEE 118-bus test system.关键词
