| Abstract: |
| The communication system and the power grid are synchronously expanded along with the development of wide-area measurement technology, which makes their interaction more complicated. The framework for researching the effect of communication system fault is proposed and the impact of electric power-communication business failure on the observability and controllability of power grid is analyzed. A method for evaluating the effect of communication interrupt fault on the business of power system real-time load control based on the optimal load shedding algorithm is proposed, which adopts the post-fault load control cost to evaluate the impacts of control equipment and communication link failures on the power grid. Case study shows the rationality and effectiveness of the proposed method. |
