Network operation and reconfiguration to maximize social welfare with distributed generations

With increasing use of distributed generations, revising management and operation of distribution network like reconfiguration, in existence of retail market and distributed generations is necessary. The aim of this paper is to present a coordinated methodology for operation and management of active and reactive power and distribution network reconfiguration with regard to costs related to active and reactive power generation of distributed generations and price of energy purchasing from retail market. On the other hand, in this paper, selecting an optimal network topology integrated with optimal using of distributed generations and retail market, including active and reactive power, has been tried to minimize related costs and satisfy technical and physical constraints. Since optimal operation and reconfiguration of distribution network is a complicated and discrete problem, the genetic algorithm has been used for implementing and solving proposed algorithm. Simulations have been applied on 33-bus IEEE test systems.
