摘 要:基于江蘇沿海地區(qū)某風電場與光伏電站實測數(shù)據(jù),研究了江蘇風電、光伏出力相關(guān)性,闡述了風電、光伏出力特性與江蘇電網(wǎng)負荷特性的關(guān)系,并統(tǒng)計分析了風電、光伏以及風光互補對江蘇電網(wǎng)峰谷差的影響,得出風光互補有利于改善風電的反調(diào)峰特性,在系統(tǒng)同樣的調(diào)峰容量下,可消納更多的新能源電力,提高系統(tǒng)的新能源消納能力。
關(guān)鍵詞:風光互補;相關(guān)性;調(diào)峰;峰谷差;消納能力

Abstract: Aiming at the defect that there exist problems of much more overshoot and voltage ripple in traditional PI control method, this paper proposed a kind of new type compound control strategy for capacitor voltage at direct current side in active power filter. The errors caused by self-adaptive detection deadbeat control were controlled repetitively to decrease the control errors further. The traditional PI control method was compared with the self-adaptive prediction deadbeat control method based on repetitive control and the control of capacitor voltage at direct current side was carried out simulation. The results show that this new type of control strategy is feasible and superior.
Key words: complementation of wind and sunshine; correlation; pitch peak; difference between peak and valley; digestion and save ability
