Abstract |
The larger and the more complicated the system size and configuration grow, the more serious the system loss problem becomes. Exessive system loss causes severs system voltage depression, which even may result in system voltage collapse. This paper proposes an effective tool for minimizing the system power loss by optimal re-location of the static condenser based on the system loss sensitivity index .lambda._{Q}. It is possible to determine the optimal location and amount of VAR investment for minimizing the system loss by priority of .lambda._{Q} index given for each bus. Several computational techniques for avoiding divergency of the load flow solution are proposed. The loss sensitivity index .lambda._{Q} uses information of normal power flow equations and their Jacobians. Two case studies proved the effectiveness of the algorithm proposed.posed. |
