Abstract
In an interconnection, frequency error and interchange power errors on tie lines are two sorts of important indices reflecting the control performance. However, these two indices may be impacted when a DC transmission line is put into operation, or an AC tie line fault occurs. In this paper, a method for evaluating the impacts is proposed, based on the theory of Area Control Error (ACE). First, the impact in the worst situation is figured. Then, we propose a model for simulating the ACE in the case when a DC tie line is put into operation, or an AC tie line fault occurs, using which we can evaluate the long-term effect. Finally, a numerical simulation is done. Compared with the real data, it shows that the method has a good performance for evaluating the impact of DC interconnecting or AC tie line fault.
