摘要
丰水期时小水电无法满发运行,成为阻碍水电资源的高效利用的重要因素。电转气(Power to Gas,P2G)设备的发展为多能互补,提升水电利用效率提供了新的手段。以小水电站收益最大为目标,构建了含P2G设备的小水电站经济运行模型。分析对比了P2G设备在不同时期对小水电站运行的影响,并进一步对比了平水期时P2G设备和储能设备对运行的影响。仿真验证了P2G设备对提升水电利用效率的有效性。
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.
