Optimizing locations and capacities of distributed generation for improving voltage quality of distribution networks
Abstract
This paper presents an optimization method for determining locations and capacities of distributed generation types in order to reduce total loss and improve voltage quality of distribution networks. The location and active power of distributed generations are determined in such a way that the total loss of active power in the network is the smallest while it still ensures constraint conditions of power balances, voltage limits at the nodes and the current limits allowed on its branches. The IEEE 33-bus test network is used to verify the proposed method in this paper. The simulation results show that when the distributed generations with optimal position and capacity are connected to the network, the total loss is reduced and voltage quality of the grid is improved significantly.
