This paper addresses a new concept for optimizing the power flow in a multilateral open access power system. Using a full AC power flow in this optimization permits the system operator to determine the optimum feasible system operating point based on predefined transactions and contracts. Inntroduction of fuzzy constraints to power transactions helps the financial entities to sell or buy their definitive and possible power with a more profitable cost while the system flexibility will increase to face with changes in operating conditions. The proposed approach is tested on IEEE RTS 24-bus network with satisfactory results.
