风光互补可再生能源发电的综合效益优化研究

在可再生能源发电系统中,为平缓系统输出功率的波动,使其可控性和稳定性更强,普遍利用储能系统作为能量缓冲装置.由于储能装置的资金投入与其容量基本上成正比,合理评估计算储能容量对于整个系统的综合经济效益较为重要.提出利用太阳能和风能的互补性,组成风光互补系统,基于频谱分析,对风、光的能量配比进行仿真计算.结合实测数据,确定了风、光最佳能量配比,减小了对储能系统的容量要求.可以优化风光互补系统的综合经济效益,为今后风光互补系统的设计提供参考.

Research on the Optimization of Comprehensive Benefits of Wind-solar Hybrid Renewable Generation System

The energy storage system is generally utilized as an energy buffer system in the renewable power generation system to obtain more controllable and continuous output power. Since its capital investment is basically proportional to its capacity, a reasonable evaluation of the storage capacity is important for the comprehensive economic benefits of the whole system. This paper proposes a wind-solar hybrid system, as well as a simulation computation of the wind and solar energy ratio on the basis of spectrum analysis. The measurement data are used to determine the optimal wind and solar energy ratio and lower the requirement on the capacity of the energy storage system. It optimizes the comprehensive economic benefits of the wind-solar hybrid system and offers a reference for its future design.
