The Comprehensive Evaluation Study On Pumped Storage Power Station's Benefits

Pumped Storage Power Station starts fast and adjusts flexibly, so it could take the tasks of peak regulation, valley filling, spinning reservation, accident reservation, phase modulation and frequency regulation in the power system. Along with the reform of Chinese electricity market, the peak regulation, safe and stable operation and reliable power supply of the power system would face more severe situation. Pumped Storage Power Station plays an important role on the security, stability and economy operation of the power system. The comprehensive evaluation study of Pumped Storage Power Station's benefits could contribute to a scientific, systematic and comprehensive understating of Pumped Storage Power Station's benefits. This plays a vital role on the construction and development of Pumped Storage Power Station, and has an important theoretical value and practical significance.In order to overcome one-sided benefits evaluation of Pumped Storage Power Station made by conventional evaluation methods, this article builds a comprehensive and integrated evaluation index system from three areas of Pumped Storage Power Station's benefits-static benefits, dynamic benefits and environmental benefits, and establish a attribute recognition model on a comprehensive evaluation of Pumped Storage Power Station's benefits. Then the model is applied to a real case-the comprehensive evaluation and analysis of Pumped Storage Power Station's benefits. The result is expected to provide a theoretical reference and decision-making basis for reasonable, accurate and scientific evaluation on Pumped Storage Power Station's benefits in future.
