Risk Assessment of Power System with Wind Farm Considering Weather Impacts

Abstract:

A method of risk assessment considering weather impacts was proposed for power system with wind power. Firstly, the mechanism of the weather affecting the risk of power system is analyzed, and then the component reliability model based on weather was illustrated. The transmission line model takes into account of 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, a new method was obtained. By using of the modified IEEE-RTS79 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 probability 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.
