【 摘 要 】

For the impact of the Dynamic line rating application on ancillary service, it is necessary to offer a better understanding of real lines capacity to the operator, in order to choose this technology as an alternative. An extended case study with the influence of applying the DLR in the Europe interconnected network is presented. This data have then been simulated through the 118-bus transmission expansion benchmark case with renewable generation capacities systems which calculated optimal investments in generation considering static rating or DLR, and provided historical time series of power flows through the interconnections in the two scenarios. Thereby, the simulation results are analysed with the objective to determine the impacts of applying the DLR on the power system's hosting capacity for fluctuating wind power infeed and the requirement for dispatchable generation units. The economic aspect is also discussed based on the simulation result of the electricity price.
