Evaluation of technical risks in distribution network along with distributed generation based on active management

Abstract

One of the main purposes of distribution network operators is increasing the participation of distributed generations (DGs). The DGs contribute in reduction of power losses, improvement of voltage profile and reliability and the postponement of network reinforcement costs. New control methods are required for DG management in order to provide more flexibility in distribution networks. In this study, the authors discuss a specific aspect of active management (AM), which is an effective approach for increasing the penetration of DG units and their management. AM is based on using the control and communication links for better operation of DGs. The effect of AM on the DG integrated distribution network in an uncertain environment is assessed. Fuzzy technique is implemented for modelling the uncertainty of loads, generation of DGs, purchased power from the grid and electricity price. By considering an uncertain environment, in this study, the effect of AM on decreasing the risk of technical issues (active loss and voltage profile) in distribution network is evaluated.
