| description | Today, with the high penetration of renewable, ensuring the safety of the system is one of the major cases in electrical system operation, thus the operator must evaluate the sensitivity analysis of the network in N-1 contingencies to be aware of the situation of the network in any failure events. In this paper, two major factors that impact the safety of the system are considered. They are the substitution of injecting power at a bus and the line outage. The paper implements a model based on these two factors to quickly identify congestions in post-contingency relating to losing a generator considered as a sudden change of a large amount of renewable energy or opening of a transmission line. Eventually, the model is tested with the 110kV transmission network of Khanh Hoa Province to identify sensitivity elements of the network which need to be considered in stability or reliability analysis. |
