摘要
针对光伏发电的波动性和随机性造成太阳能资源利用率低,光伏企业经济效益较差及其他间接成本高的问题,通过对实际工程的研究,本文提出了储能系统能量时移作用方法。结果表明:储能装置能量时移方法可有效减少光伏电站弃光现象,降低旋转备用容量补偿成本、AGC调频容量补偿和可靠性成本及电网扩建成本和环境治理成本,提高光伏发电系统的潜在经济效益。
The fluctuation and random of the photovoltaic power generation cause the low utility of the solar energy resources,the poor economic benefit of the photovoltaic enterprises and other high indirect cost.Aiming at the above problems,by the study of the practical engineering,puts forward the method of energy time shift effect of energy storage system.The results show that the method of energy time shift effect of energy storage system can effectively reduce the power abandon phenomena of the photovoltaic power station,decrease the compensation cost of whirling standby capacity,AGC frequency regulation capacity compensation,reliability cost,power grid expansion cost and environmental treatment cost,and the method can promote the potential economic benefit of the photovoltaic power generation system.
