Prevention and Control Method of Security and Stability Risk for Power System with Large-scale Wind Power Integration
Aiming at the challenge of wind power output uncertainty to the safe and stable operation of power systems
a prevention and control method for security and stability risk of power systems with large-scale wind power integration is proposed. Considering that the optimization objective is to minimize the control cost of preventive control measures
including the control cost of adjusting the output of thermal power units and the curtailment risk of limiting the output of wind power clusters
the allowable operation risk is transformed into opportunity constraints with reference to the accident level evaluation standard of the power system. By calculating the control performance indices of thermal power units and wind power clusters
the effective control measures are selected
and the control quantities of effective control measures are classified and enumerated to obtain all possible control schemes. The control schemes are verified by parallel implicit enumeration based on the cluster parallel computing platform to obtain the control measures that meet the target function. The example analysis of a practical system verifies the practicability and effectiveness of the proposed method.
