Optimal location of DG and FACTS devices under Maximum loading Capacity

The Distributed Generator (DG) unit nowadays have become an integral part of any power system network. For the effective management of power flowing in a network, the size and position of the DG unit play the important role, but DG integration on the other side, also affects the operating characteristics of the system such as losses may be increased or decreased, variation in voltage and increases the cost for consumers or generators. To eliminate such effects, it is proposed that DG units can be integrated with FACTS devices, as these devices provide more reliability to the network. On the other side, load demand is also increasing day by day therefore, to fulfil the demand it is required to make use of these DG units at various locations. In this paper, an analytical approach with optimal power flow (OPF) method is used in MATLAB environment to identify the optimal location of DG and FACTS devices in maximum loading condition.
