Application of active management in operation of distribution network using NSGA II

One of the main aims of distribution networks is increasing the participation of distributed generation. One of the methods that can determine the maximum penetration of DG in distribution network is use of active network management. Active network management has essential role to facilitate the connection of new generations without need of reinforcement traditional network. This paper proposes a multi- objective idea based on minimizing costs of active and reactive power of DGs and network. In addition, the mentioned objective function is includes cost of active power losses and reactive power generated (absorbed) by Reactive Power Compensators (RPC). The proposed objective function is determined based on optimal power flow and with considering the technical constraints. For active management of distribution network, coordinated control of voltage and reactive power of network equipment are implemented. Non-dominated Sorting Genetic Algorithm (NSGA II) is employed to solve the optimization problem.
