Transmission Sections Search Method Based on Weighted Maximum Edge Betweenness
In order to use transmission sections to reduce the dimension of power system,search of transmission sections based on complex network theory is carries out.The weighted maximum edge betweenness is proposed to divide the power network.The influence of network topology and Current operation mode on the dividing is both considered.The weighted maximum edge betweenness trims the defect of edge betweenness who takes the shortest path as the only path of power flow,so it prevents the subarea division form ignonng some important transmission lines.The ending criterion of subarea division is proposed to effectively utilize the key branches,which reduces the computation amount and prevents the isolated nodes from being a single zone.Finally,transmission sections are obtained by searching the cut sets of network based on the subarea division.A case study of practical system verifies the feasibility of this method.Compared with the other two methods.this one neither depends on the selection of overload branches,nor requires the calculation of all cut sets,which can be better applied to the actual power grid.
