火电厂光火储一体多能供给系统的应用分析

Analysis of the Application of Solar Photovoltaic,Coal-fire,and Storage Multi-energy for Thermal Power Plants

光伏发电在低碳节能的能源体系构建中起到了重要的作用,但由于其自身的不确定性和波动性,给电力系统的可靠性和灵活性造成了挑战,因此使用多能互补技术,提升电能质量是行业发展的必然选择。本文介绍了某电厂的光火储一体多能互补供电系统,并对其运行效果进行分析,结果显示:本系统25年内可累计节省年发电量854.76万千瓦时,总经济收益387.21万元。本光火储一体系统能有效充分利用各种能源,在提高能源利用效率的同时,保证电能质量,减少能源供应成本,对火电厂应用“光伏+储能”发电有借鉴意义,值得推广。

Photovoltaic power generation plays an important role in the construction of a low-carbon and energy-saving energy system,but due to its own uncertainty and volatility,it poses a challenge to the reliability and flexibility of the power system.Therefore,the use of multi-energy complementary technology to improve power quality is the inevitable choice of PV industry development.This paper introduced a solar-coal-storage integrated multi-energy complementary power supply system for a power plant and analyzed its operation effect.The results showed that this system could save a total of 8,547,600 kWh of annual power generation in 25 years,and had obvious economic benefits with a total gain of ￥3,872,100.The solar-coal-storage integrated system could effectively make use of all kinds of energy,improve energy utilization efficiency,ensure power quality and reduce energy supply cost.This system has certain significance for the application of "photovoltaic + energy storage" power generation in thermal power plants,and is worth promoting.
