以太阳能-水联合发电系统为对象,基于抽水蓄能运行模式,提出了独立运行、并网运行和恒功率输出三种运行方案。在建立联合发电系统数学模型的基础上,分析了三种运行方案的实现方法。仿真试验结果表明,三种运行方案均具有可行性和有效性,且太阳能与水的能量互补效果显著,太阳能-水联合发电系统具有较高的能量利用率,并从提高能量利用率的角度探讨了上水库库容、水源和光伏电站装机容量问题。
Taking the solar-water power generation system as an example, three operation schemes of independent operation, grid-connected operation and constant power output are put forward based on the operation mode of pumped storage. Based on the establishment of the mathematical model of the combined power generation system, the methods to realize the three operation schemes are analyzed. The simulation results show that the three operation schemes are feasible and effective, and the energy complementarities between solar energy and water are significant. The solar-water power generation system has a higher energy utilization rate, and from the perspective of improving the energy utilization rate Up reservoir capacity, water and photovoltaic power plant installed capacity issues.
