Abstract :
Distribution system companies (DISCOs) can reduce their cost by reconfiguration as the economic way for loss reduction. This paper presents a new method for reducing DISCO costs in deregulated environment by loss reduction and power generation control of Distributed Generators (DGs). Because of changing the price of energy in this environment, different network load levels with different prices were considered. This complex optimization problem is solved by a new method based on shuffled frog leaping algorithm (SFLA). Also, influence of DG presence on objective function and load flow is considered. The proposed method is applied to IEEE 33-bus and 69-bus test systems to decrease the activity cost of DISCO in deregulated environment and its capability relative to other methods is shown.
