The Design of the Model of Wind Power Integration Based on Thermal Power Peak-shaving

With the country promoting the power from new energy sources, wind power was attached with great importance gradually. However, there is an existing major problem in the field of wind power, that it is the lack of peak-shaving capacity, which leads the capacity of wind power integration to be limited. For solving the problem of the lack of peak-shaving capacity, the models of "equivalent load" and "equivalent power injection" and the wind power integration model based on thermal power peak-shaving capacity is built in this paper, which takes controlling the capacity of wind power integration reasonably as target. The model can forecast the maximum power of wind power integrated in the power grid in real time. The reasonability of the model is verified by an actual example. Furthermore, for obtaining more social benefits and economic benefits, this paper analyzes wind power control strategies in both cases of conventional peak-shaving and deep peak-shaving. Finally, the paper gets the following conclusion. In the case of conventional peak-shaving, wind power should be controlled reasonably according to the peak-shaving capacity of thermal power. In the case of deep peak-shaving, peak-shaving cost should be increased for eliminating the crowding-out effect.
