چکیده مقاله :

Nowadays, congestion management is one of the major tasks accomplished by system operators to warrant the operation of transmission system within operating limits. This has resulted in unanticipated congestion interfaces in regional transmission systems. The system is, however, unable to evolve at a rate which is required to meet the quickly changing demand of competitive markets. To make the matters worse, the functional unbundling of generation company and system operator will further threaten reliable operation of entire grid due to the lack of coordination between generation and transmission. Thus, a sensible way of dealing with congestion has become vital to maintaining current level of high reliability. In this paper Firefly Algorithm (FA) is used for solving economic load dispatch problem for raise efficiency, increase safety margins and reduce cost of distribution network unit production regarding to practical constraints such as maximum network voltage, maximum transmission line current, power balance and load level. The proposed technique is applied on 30 and 118 buses power system in comparison with CPSO, PSOTVAC, PSOTVIW and ABC
