Determination of unserved load and distributed generation for power system planning purposes

A fundamental step in power systems planning is the distribution of the load in the network. By the actual structure of electricity markets and the consideration of massive growth of distributed generation units, it is necessary to consider the influence of these connection points in power system planning. It has to be investigated how this effects the reduction of the active power losses and the load distribution in the network. This paper outlines a method on how the load in the network can be forecasted and the location of the distributed generation units. The proposed method is based on the spatial distribution of the load, parameter of the network and active power losses caused by each new generation facility. The model is applied to a real system showing the potential for its use.
