Abstract :
Under deregulation, the loads are difficult in forecasting, there are large differences between the actual demand of electric power and the load forecast in bulk power system. Transmission planning becomes very complex under deregulation. It is very important to transmission planning that analyzing and evaluating of the transmission network adaptability to the future loads. This paper adopts DC power flow method and branch-node real power sensitivity to evaluate the transmission network adaptability to node load. The adaptability to node load includes single-node real power load and the total of all nodes real power load. Garver-6 test system illustrates the adaptability evaluation method is effective and feasible, and it can offer the guidance signal to new additional generation connection.
