Study On The Acceptance Capacity Of Wind Power Under The Yangjiang Grid Peaking Constraints

China’s wind power cannot successful interconnection is the main reason for power grid peak shaving ability is insufficient, therefore, according to the analysis of the limit load performance, can effectively improve the efficiency of solving the problem of power grid peak shaving.Wind power grid scale increasing, sometimes, period of time in wind power grid peak shaving is affected by the negative, so if you want to wind power into the grid system, must ensure that the former does not exceed the load of power grid can accept ability. The reason will appear this situation, with factors such as wind power, wind power fluctuations between close contact. According to these three elements, this paper expounds in detail and, on the one hand, the quantitative analysis of the influence of large-scale wind power on power grid peak shaving, and on this basis, establish a load capacity as the constraint of wind power capacity calculation, effectively restrain power grid peak shaving capability.In order to further understand the detailed characteristics of large-scale wind power output power, an actual operation data of four wind farm as sample. Through the analysis of the data sample, describing \ "single- a single wind farm- wind group of\" power output characteristics, convenient for further research of the relationship between mass and wind power grid peak shaving.The author active on wind farm output and load effect between each other, the wind power the load after an in-depth analysis, found the most unfavorable acceptance period is between load low moment; Combined with the feature of wind farm power output of a cluster effect, parsing load performance of the conventional power, at the same time find out the most suitable method, capacity constraints on peak trough time under wind power capacity calculation.Above all, on the basis of planning of yangjiang power again, calculated in 2015, yangjiang trough time large and small ways winter winter load of power grid wind power acceptance capacity; At the same time in order to adopt the method of practice research, yangjiang for an argument, boot method and load of power grid through the check to determine the best parameters.
