Optimal Long Range Transmission Planning with AC Load Flow

摘要: This paper describes a new procedure for the optimal long range expansion planning of transmission network. In addition to providing an plan, set cost competitive plans can be generated. System is specified in terms discrete lines and two kV levels. Economic impact factors such as escalation, economy scale, right-of-way unavailability, external system interconnections, etc., are incorporated formulation. A dynamic optimization based on nonlinear branch bound algorithm employed. The resulting plan specifies when, where, what type construction should occur. unique feature method, which reduces considerably computational burden, automatic generation alternatives associated procedures elimination infeasible non-optimal early process. Computational speed also affected by user option employing either dc or ac load flow calculations.
