Abstract

IN THIS PAPER, FIRST, WE INTRODUCE UPFC MODEL AND DERIVE ITS EQUATIONS USING TWO POLE CIRCUIT PROPRIETIES. THEN WE EXPRESS OPTIMAL POWER FLOW (OPF). OBJECTIVE FUNCTION IN THE OPF, THAT IS TO BE MINIMIZED, IS TOTAL PRODUCTION COST FUNCTION OF THE GENERATORS. THE OPF CONSTRAINTS ARE GENERATORS, TRANSMISSION LINES AND UPFCS LIMITS. WE PROPOSE GENETIC ALGORITHM WITH AN EFFECTIVE FITNESS FUNCTION TO CONSIDER THE OBJECTIVE FUNCTION AND ALL EQUALITY AND INEQUALITY CONSTRAINTS. ALSO WE EXPLAIN IMPLEMENTATION OF THIS METHOD. WE DRIVE DC LOAD FLOW IN POWER SYSTEMS CONTAINED UPFC. DC LOAD FLOW IS USED TO SOLVE THE OPF PROBLEM. WE APPLY THE PROPOSED METHOD TO A TEST POWER SYSTEM AND STATE ITS RESULTS. THE RESULTS SHOW GOOD EFFICIENCY OF THE GENETIC ALGORITHM AND PROPOSED FITNESS FUNCTION TO SOLVE THE PROBLEM WITH ALL GENERATION AND TRANSMISSION AND UPFC CONSTRAINTS. ALSO WE SHOW THAT THE UPFC CAN CONTROL THE POWER FLOW IN LINES AND HELP KEEP RE-DISPATCHED VALUES OF GENERATORS TO CLOSE TO PREFERRED SCHEDULES. THE UPFC CAN BRING THE SYSTEM INTO A FEASIBLE OPERATING CONDITION IN CASES WHERE SECURITY CANNOT BE ACCOMPLISHED WITH EXISTING NETWORK CAPACITIES AND MAY ALLOW MORE CONTRACTS TO BE HELD IN A RESTRUCTURED ENVIRONMENT.
