Investigating and simulating DGs to improve voltage profile and reducing power loss in unbalanced distribution networks [PDF]

, 2014
Development of Distributed generations (DGs) has changed the nature of power networks from passive to active. In order to specify a proper model for DG units, function and connection style of DGs to the network (direct or indirect) must be clarified.
