摘要
太阳能发电功率逐日增加,以往单一的光伏发电系统并网运行的可调度性和可控性不足,提出了一种新的混合发电系统以提高调度的灵敏性。此系统包括风电场、光伏电厂、光热电站和电加热器。电加热器主要是将多余的风能、光能转化为热能并储存在太阳能发电厂的储热罐中,利用储热光热电站良好的可调度性和可控性,提高系统的旋转备用和爬坡能力,削减风光出力随机性与不确定性,从而提高新能源的消纳量。以系统净收益最大为目标建立模型,在技术约束下最大限度地提高系统利润并研究了不同气候条件下混合发电系统对新能源消纳的影响。
Solar power is increasing day by day,and the scheduling and controllability of the previous single photovoltaic power generation system running on the grid are insufficient.A new hybrid power generation system is proposed to improve the sensitivity of scheduling.The system includes wind farms,photovoltaic power plants,solar thermal power plants and electric heaters.The electric heater is mainly to convert the excess wind and light energy into heat energy and store it in the heat storage tank of the solar power plant.By using the good scheduling and controllability of the heat storage thermal power station,it improves the rotating reserve and climbing capacity of the system,reduces the randomness and uncertainty of the scenery output,so as to improve the consumption of new energy.In order to maximize the net income of the system,the model is established to maximize the system profit under technical constraints,and the influence of the hybrid power generation system on the new energy consumption under different climate conditions is studied.
