Abstract :
An improved analysis approach for wind power integration capacity (WPIC) is proposed. In this paper, WPIC is composed of two parts, one provided by hydro power and the other provided by thermal power. After proper consideration of wind power randomness, WPIC provided by hydro power is determined by the regulation ability of reservoir in hydro power plants. Then, a concept of equivalent thermal power units output duration curve is proposed to accurately evaluate WPIC provided by thermal power in a probabilistic perspective. Numerical tests are conducted on Gansu power grid in 2015. Monthly WPIC under different scenarios are determined, which validates the effectiveness of this approach.
