Vulnerable Node Assessment of Power System With Double-fed Wind Farms
With the development of wind power, it has the characteristics of stochastic volatility and absorbing reactive power on grid, so the wind power become a disturbances source of power grid, and further impact on the vulnerability of the system. This paper combined static energy function model with electrical betweenness and proposed a new set of comprehensive assessment indicators which reflect both the state of a node of vulnerability and fragility of the structure. At the same time, made discrete indicators serialization; got a set of comprehensive assessment indicator that changes with time. By building grid model with double-fed wind farm and simulating, this paper got a continuous curve that comprehensive assessment indicators changes with integrated wind, and compared different access points the changes in the vulnerability of the system nodes, and the results were analyzed.
