This paper proposes an efficient methodology to optimally determine the best location and optimum size for Distributed Generators (DG), in a distribution network, while minimizing energy losses and improving voltage profile. The proposed methodology has been designed to consider variable demand and variable DG production scenarios, offering a set of optimum values for DG active power output and power...
The rapid increase of distributed generations (DGs) has many benefits for distribution systems and could result in some negative effects. Identifying the optimum locations and sizes for these units increases the benefits and limits the negative effects. Many researches tried to define the optimal DG siting and sizing. Either normal operation or faulty conditions have been considered in this process...
Penetration of Distributed generation (DG) in a distribution system changes the fault current and unidirectional nature of power flow. This leads to loss of coordination between various relays present in the system. This paper discusses formulation of the problem to determine optimal relay settings of an overcurrent relay with and without DG added to a system. A proper combination of primary and backup...
This paper proposes a service restoration algorithm considered with priority customers and Distributed Generation (DG). By establishing an index of service restoration rate considering load grade, the power supply to the priority customers is ensured. Taking advantage of DG with regard to the service restoration in distribution networks, when the grid does not have enough capacity to restore the entire...
