Low voltage distribution planning considering micro distributed generation

•It solves the problem of size, quantity and siting of distribution transformers in low voltage distribution network.•This paper takes into account the micro distributed generation injected by the costumers.•The model optimizes an objective function that considers the investments and operational costs of the electric network.•This paper includes aspects such as the evaluation of three-phase power losses and system reliability evaluation.

This paper presents further advances to the low voltage distribution optimization problem by considering micro distributed generation injected by costumers. To this purpose the proposed model presented in [1] has been improved including aspects such as the evaluation of three-phase power losses, system reliability evaluation and mainly the impact of micro distributed generation (micro DG) on the overall process of Low Voltage (LV) network planning. Finally, results are shown on the application of the algorithm on a test and real urban networks.
