Transmission Expansion Planning Using Loss of Capacity Probability Tables in the Generation-transmission Model

Electrical power systems, in the generation - transmission stage,have great importance worldwide. These systems are the way todistribute large amounts of electrical energy from the electricalgeneration centers to different kind of consumers. The generation– transmission system expansion planning is highlyrepresentative, so meeting the demand response and its growth isthe challenge for companies which are in this line of business. Inthis work, the generation – transmission system expansionplanning is carried out in a test system through two phases. In thefirst phase, an algorithm is developed to build capacity lossprobability tables and use reliability criteria to determine newgeneration projects necessary to cover demand and have thenecessary reserve for a defined planning horizon year. Using theresults of the first stage, the second phase begins, in this stage anoptimization algorithm is used for a mixed integer linear problemand application of the optimal DC power flow to determine thetransmission projects necessary to connect, to the base system,the new generation projects determined in the first phase and theiroptimal power dispatch to minimize investment and operatingcosts.
