基于新能源的电力经济调度分析研究

Analysis and Research on Dispatch of Power Economy Based on New Energy Source

随着全球对新能源需求的日益增长,风能、太阳能等新型能源得到了广泛的关注,逐渐成为能源体系的重要组成部分,但是由于其随机性、间歇性的特点,也对电力系统的稳定运行产生了影响。本文将新能源引入到电力系统经济调度中,搭建了基于多种能源组合的电力系统经济调度模型,将新能源容量引入到电力系统经济调度的成本控制函数中。对调度模型进行了仿真,结果表明新能源发电并网后,发电成本显著下降,证明了新能源的经济效益。在进行基于新能源组合经济调度条件下,多种能源组合并网发电的输出功率更加稳定,加强了电力系统的供需平衡性。该电力经济调度方案适宜在加入新能源并网条件下大规模推广应用。

With the increasing global demand for new energy sources,new energy sources such as wind and solar energy have gained widespread attention and gradually become an important part of the energy system,but due to their random and intermittent characteristics,they also have an impact on the stable operation of the power system.This paper introduces new energy sources into the economic dispatch of power system,builds a power system economy dispatch model based on the combination of multiple energy sources,and introduces new energy capacity into the cost control function of power system economic dispatch.Simulations of the dispatching model are conducted,and the results show that the cost of power generation decreases significantly after the new energy generation is connected to the grid,proving the economic benefits of new energy.Under the condition of conducting economic dispatch based on new energy combination,the output power of multiple energy sources combined with grid-connected power generation is more stable,which strengthens the balance of supply and demand of the power system.This power economy dispatching scheme is suitable for large-scale application under the condition of joining new energy sources to the grid.
