Optimal power flow emulation of interchange brokerage systems using linear programming

摘要

The authors propose an interchange brokerage system based on an optimal power flow (OPF) solution using linear programming (LP). Interchange brokering schedules power imports and exports between interconnected electric utilities to maximize profits for all participating parties and enhances the security of power systems. The data required for interchange brokerage systems are the amount of power available for trading and the system incremental cost. An LP software package called STORM was used to solve the active and reactive OPF subproblems and the interchange brokerage systems. The steps required for the implementation and problems involved in loss minimization are considered. The development of LP theory for OPF and interchange brokerage systems and its limitations are discussed. The experimental results are included.
