Quantitative Method of Wind Power Peak Shaving Cost Based on Mean Output

With the rapid development of large-scale wind power, the demand for peak shaving service in power system is increasing, and the cost of peak shaving service is also increasing. Reasonable calculation of peak shaving service cost caused by wind power is the premise to encourage conventional units to provide peak shaving service. Proposes a quantitative method of peak shaving cost caused by wind power, which is called wind power mean reference method. In this method, the output of wind power in a certain period is evenly distributed to each dispatching period to obtain the reference scenario for peak shaving cost calculation by wind power average output profile. Then the peak shaving cost in specific scenarios can be calculated and expressed clearly based on this average output profile. The proposed method is verified on a 5 thermal power units system with wind farm, and the results demonstrate the correctness and effectiveness of the proposed method.
