Fuzzy Set Pair Analysis Method and Its Application in Multi-objective Transmission Network Planning

摘要

A novel method of Fuzzy Set Pair Analysis (FSPA) is introduced to solve the problems in multi-objective transmission network planning. In the planning model economics, reliability and flexibility are emphasized as three important factors to evaluate the schemes. Economics and reliability are indicated by the investment cost and the outage cost respectively, and flexibility of the network is quantified by Available Transfer Capability (ATC) for the first time. By employing the FSPA method, these objectives are independently evaluated from viewpoints of identity-discrepancy-contrary (IDC), and then assembled into single index. The evaluation is more comprehensive and can provide more information for expansion decisionmaking. An actual example is given to demonstrate the effectiveness of the proposed model.
