摘 要:豐水期時小水電無法滿發(fā)運行,成為阻礙水電資源的高效利用的重要因素。電轉(zhuǎn)氣(Power to Gas,P2G) 設(shè)備的發(fā)展為多能互補(bǔ),提升水電利用效率提供了新的手段。以小水電站收益最大為目標(biāo),構(gòu)建了含P2G設(shè)備的小水電站經(jīng)濟(jì)運行模型。分析對比了P2G設(shè)備在不同時期對小水電站運行的影響,并進(jìn)一步對比了平水期時P2G設(shè)備和儲能設(shè)備對運行的影響。仿真驗證了P2G設(shè)備對提升水電利用效率的有效性。
關(guān)鍵詞:小水電站;電轉(zhuǎn)氣設(shè)備;儲能設(shè)備;經(jīng)濟(jì)運行

Abstract: Small hydropower can't maximize its benefits in the wet period which impedes the efficient use of hydropower resources. The development of power to gas (P2G) facilities was multi-complementary to provide the new means for the improvement of hydroelectric utilization efficiency. This paper established a small hydropower economic operation model taking the maximal profit of small hydropower as the goal, and analyzed and compared the impact of P2G facilities on the operation of small hydropower stations in different periods. Furthermore, this paper compared the impact of P2G facilities and energy storage facilities on operation in the normal season. The simulation shows the effectiveness of P2G facilities in improving hydropower efficiency.
Key words: small hydropower; power to gas facilities; energy storage facilities; economic operation
