A New Approach for Optimal Allocation and Economical Capacity of Generation Reserve

Determination of the installed reserve capacity is an essential part of the power system planning. Considering the network limitations, not only the amount of installed reserve capacity, but also the location of this capacity is an essential factor in improving the reliability level of the system. A new appoach to select the most suitable locations for the installed reserve capacity and its distribution between these locations was developed. The problem was formulated as a mathematical programming problem and was efficiently solved using linear programming technique. The optimal reserve capacity in the system was calculated as the amount which minimizes the total system costs, with the capacity added at the preselected locations. The developed approach was applied to the 220 KV system of A.R.E The final results are presented and discussed in this paper.
