Abstract:
The paper proposes a distribution network planning method to be used in low voltage (LV) networks. Future development of power grids must pursue different goals; the main objective of network planning is to determine a technical and economical optimal solution that will enable long-term quality electrical supply. Established planning guidelines are not uniquely determined regarding the introduction of distributed generation (DG) and how they should be taken into account. Further integration of DG should not be limited, despite their substantial impact on network performance. The presented method is based on statistical approach. Due to the fact that LV networks reflect stochastic nature and that the future location of DG in the network is usually unknown, the network planning is upgraded using Monte Carlo method. With random patterns and repetition of experiments the voltage situation in the future can be assessed and thus results of different voltage management strategies compared. For the evaluation of the presented planning method, the simulations were carried on an actual LV Slovenian distribution network model.
