摘要
光伏电站受昼夜、季节、天气、温度等的变化,发电出力具有一定的波动性、随机性、间歇性;配置了大容量储热系统的光热电站,具有与光伏电站联合运行、提高发电利用小时数、提高外送通道利用率的潜力。文章通过研究发现：尽管光伏和光热电站发电在时间上不具备自然互补性,但通过储能系统的移峰填谷是可以实现互补的;考虑现阶段光热发电的发展水平,从电力平衡角度看,其装机容量配比应为1∶1。研究表明,仅有光伏和光热2种电源互补的供电保证率约为80%~90%,还需要其它多种能源形式对其进行补充。
The CSP output features fluctuation,randomicity and intermittence because of such changes as daytime and nighttime,seasons,weather and temperature,etc. The CSP equipped with the large- capacity thermal storage system,jointly operating with PV power plant,is with the potential of increasing power generation hours and improving the availability of power evacuation facilities. The study in this paper presents that both PV plant and CSP are complementary via the load peak adjustment and load valley filling of the energy storage system although they are not complementary in term of time. In consideration of the CSP development level at present,ratio of the installed capacities of PV power plant and CSP shall be 1∶ 1. The study also demonstrates the availability of power supply of hybrid of PV power plant and CSP only is 80% ~ 90% approximately. Other kinds of energy are demanded to complement further.
