Distributed energy resources (DERs) of Smart Grids should actively participate in the control of grid state variables frequency and voltage through their interfaces, namely inverters. As these DERs are joining the existing conventional power systems, they must follow the existing grid control. However, standard communication between utilities and consumers(More)
The power generation in power systems nowadays changes from the traditional centralized to contemporary decentralized structure that disperses widely in distribution grids. It results in power generation from the bottom level, i.e. in local area, which is contrary to the traditional centralized power generation that provides power flow in top-to-down(More)
Currently in the power supply system, a large number of decentralized energy conversion systems (ECSs) based on renewable energy sources (RESs) and intelligent infrastructures are installed into the conventional power systems in order to build up “Smart Grid”. These leads, the power systems have to be carefully clarified and managed for grid(More)
A new approaches of energy supply system management has been widely discussed due to a penetration of distributed generation based on renewable energy resources in distribution network. One approach to accomplish distribution network management is to turn a passive distribution network to be an active network like conventional transmission network, in which(More)
