【摘要】：提出了一種在現(xiàn)有電源結(jié)構(gòu)水平下利用棄風優(yōu)化風電場裝機容量的方法。在滿足系統(tǒng)靜態(tài)安全約束的條件下,基于機會規(guī)劃約束,建立了以風電場凈收益最大為目標、計及棄風的風電場最優(yōu)裝機容量模型。在此基礎(chǔ)上,以小時為時間尺度,將風電不同季節(jié)、不同時刻調(diào)峰特性對棄風電量的影響引入最優(yōu)模型,通過精細化模型得到統(tǒng)計意義上更為合理的最優(yōu)裝機容量。最后,以IEEE 30節(jié)點系統(tǒng)為例,基于某風電場的年風速分布特性及典型日每時刻的風速分布特性,采用基于隨機模擬的粒子群算法進行模型求解,分析計算棄風、時間尺度、上網(wǎng)電價及其他因素對風電場裝機容量的影響。
[Abstract]:A method of optimizing the installed capacity of wind farm by using abandoned wind at the level of existing power supply structure is presented. Under the condition of satisfying the static security constraints of the system, a model of optimal installed capacity of wind farm with the maximum net benefit of wind farm and considering the abandoned wind is established based on the constraint of opportunity planning. On the basis of this, the influence of peak shaving characteristics of wind power at different seasons and different times on the output of abandoned wind power is introduced into the optimal model based on the hour as the time scale, and the more reasonable optimal installed capacity in statistical sense is obtained through the refined model. Finally, taking the IEEE 30-bus system as an example, based on the annual wind speed distribution characteristics of a wind farm and the wind speed distribution characteristics of a typical day at every moment, the particle swarm optimization algorithm based on stochastic simulation is used to solve the model, and the abandoned wind and time scale are analyzed and calculated. The influence of electricity price and other factors on installed capacity of wind farm.
