Risk Assessment of Power System with Wind Farm Considering Weather Impacts
A method of risk assessment considering weather impacts is proposed for power system with wind power.Firstly,the mechanism of the weather affecting the risk of power system is analyzed,and the facilities reliability model based on weather is established for wind turbine,transmission lines and other system components,among which the transmission line model taks into account the situation that the line may pass through a variety of climatic zones.Secondly,combine the above-mentioned model with the existing risk assessment methods,and proposes a new risk assessment method for power system with wind farm considering weather impacts,as well as its specific assessment procedures.Through the modified IEEE-RTS79 node system with wind power,the feasibility and reasonableness of the proposed model and approach are verified.The results show that it is necessary to consider weather especially when the system is integrated with large-scale wind power or the system passes through zones with particularly higher possibility of bad weather.Compared with the existing risk assessment methods,the proposed method is more in line with the actual system,and the assessment results are more reasonable.
