Two new indices for the assessment of regional transmission connection capacities

Güverçinci, Ali Haydar
Traditionally electrical power industry has been regulated and monopolized. However, since 1980s it has undergone a period of restructuring throughout the world. This privatization procedure has made the planning and operation of the generation, transmission and distribution parts of power system relatively more independent and disconnected. The transmission system planners lost their direct control over plant investments. As a result, planning of the transmission system became more complex than it ever was. This created a need for mechanisms to assess the economics and reliability of transmission expansion planning. This thesis presents a methodology to determine the maximum amount of new generation that can safely be connected from a region to the transmission system. Two new indices are developed to monitor impact of additional generation in a specific region. The first index examines the effect of additional generation to the transmission system as a whole by taking into account the overloading amount and possibility of each line in the region. The second index identifies the weak points in that region that needs to be strengthened by evaluating the impact of the additional generation on each line separately. The proposed methodology was applied to Turkish Transmission Network model of 2026 considering four different case studies. These are peak demand and minimum loading scenarios where high and low wind energy investments are considered separately.
