【摘要】：電池儲能系統(tǒng)(BESS)可使風(fēng)電場具備一定的發(fā)電計劃跟蹤能力,有必要研究風(fēng)電場中的BESS容量優(yōu)化問題。根據(jù)BESS技術(shù)特性與風(fēng)功率波動特性制定發(fā)電計劃,BESS分兩部分運(yùn)行,分別處于充、放電狀態(tài),交替平抑風(fēng)功率與發(fā)電計劃間的正、負(fù)偏差。一旦任一部分BESS到達(dá)滿充或滿放狀態(tài),則同時切換兩部分BESS的工作狀態(tài)。采用蒙特卡洛模擬技術(shù)對風(fēng)-儲混合電站一年內(nèi)的運(yùn)行狀況進(jìn)行模擬,并計算發(fā)電計劃跟蹤概率與BESS運(yùn)行利潤。在確保風(fēng)-儲混合電站按期望置信度跟蹤發(fā)電計劃的基礎(chǔ)上,依據(jù)利潤最大化的原則對BESS容量進(jìn)行優(yōu)化。基于某風(fēng)電場歷史數(shù)據(jù)的仿真實驗證明了所提模型及算法的有效性。
[Abstract]:The battery energy storage system (BESS) can make the wind farm have the ability to track the power generation plan. It is necessary to study the optimization of BESS capacity in the wind farm. According to the technical characteristics of BESS and the characteristics of wind power fluctuation, the power generation plan is made. The BESS is operated in two parts, which are in charge and discharge states respectively. The positive and negative deviations between the alternately balanced wind power and the generation plan are determined. Once any part of the BESS reaches the full charge or full discharge state, it switches the working state of both parts of the BESS at the same time. Monte Carlo simulation technique is used to simulate the operation of the wind-storage hybrid power station within one year, and the tracking probability of the power generation plan and the operation profit of the BESS are calculated. According to the principle of profit maximization, the capacity of BESS is optimized on the basis of keeping track of the scheduled reliability of the wind-storage hybrid power station. Simulation experiments based on historical data of a wind farm demonstrate the effectiveness of the proposed model and algorithm.
