Determination of regional transmission connection capacities in a deregulated environment

Assessment of regional transmission connection capacity based on two novel indices

“…During the study, authors add new generation units gradually to supply area until the N − 1 limit is reached. The transmission system planning of Turkey is evaluated in [12], such that capacities of pre‐determined regions are found step‐wise. In [13], a method is presented for transmission system capacity assessment for generation connection using pre‐fault and post‐fault conditions.…”

“…This paper proposes use of two novel indices to determine the transmission connection capacity which indicates the amount of generation that can be connected to the network from a specific region in a safe manner. While a single capacity is calculated in [11, 12], in this study three different capacity values are calculated for each region based on those two indices, namely region‐based evaluation index (REI) and line‐based evaluation index (LEI). REI‐based transmission connection capacities are useful for evaluating the reaction of the regional system against additional generation, while LEI‐based capacity determines the weak points of the considered network, and the possible generation increment without any transmission system investment.…”
