考虑制氢设备效率特性的煤风氢能源网调度优化策略
|
摘要
风电的反调峰特性导致在调度过程中机组压力大、存在严重的弃风现象,建设大型可转移新能源消纳设备是一个可能的解决思路。该文提出了将大型新能源消纳设备的负荷特性纳入考量的煤风氢能源网综合调度优化策略。首先建立了典型新能源消纳设备——电解水制氢设备的产出模型,研究其在不同运行功率下的效率–功率特性关系。在此基础上,以产出电力与氢气的复合煤风氢能源网整体利益最大化为目标对网内常规机组、风电及制氢设备进行短期调度经济性优化。仿真结果表明,依据消纳设备效率特性关系可制定出更为精准、灵活、经济的调度运行策略,在保证煤风氢能源网风电消纳能力的同时,提高了常规机组和消纳设备的运行经济性。该文为含风电场、制氢设备的煤风氢能源网的经济运行策略制定提供了一个全新的视角。
The reverse peak characteristics of wind power lead to unit operating pressure and a serious phenomenon of abandoned wind, and equipping large-scale transferable new energy consumptive devices is a possible solution. This paper presented the integrated energy scheduling optimization strategy in the coal-wind-hydrogen energy grid which takes the load characteristics of hydrogen production equipment into consideration. Firstly, the production model of hydrogen production equipment, as the typical large-scale transferable new energy consumptive devices, was established, and the relationship of the efficiency-power characteristics under different operating power was studied. On the basis of this model, aiming at maximizing the overall benefits of the combined energy network producing electricity and hydrogen, the short-term dispatching economic in the network with conventional units wind power and hydrogen production equipment was optimized. The simulation results verify that a more accurate, flexible and economic operating strategy can be made according to the efficiency characteristics of consumptive equipment, which improves the operation economic of conventional units and consumptive equipment, and ensures that the energy of wind power is consumed at the same time. The paper provides a new vision of optimizing the economic operation strategy of energy net with wind farm and large-scale new energy consumptive equipment.
