Operational risk assessment of electric-gas integrated energy systems considering N-1 accidents

... This paper establishes a risk assessment system of electric-gas integrated energy system (EGIES) considering the risk security of components. According to the mathematical model of each component, the EGIES steady state analysis model considering the operation constraints is established to analyze the operation status of each component. Then the EGIES component accident set is established to simulate the accident consequences caused by the failure of each component to EGIES. Furthermore, EGIES risk ...

Forecasting the Total Transfer Capability of Intersystem Lines for On-line Control of Electric Power System Operation

... Dynamic state estimation yields the predicted values of the state variables. Modified state estimation calculates the total transfer capability on the basis of the forecast data. The obtained state is called the resultant steady state. Depending on operation constraints, the modified state estimation program parameters to be adjusted to provide optimal result of the modified state estimation are taken from the database by using ANN, and the resultant state variables of the interconnected power system ...
