| 摘要: |
| 配置电锅炉可削热峰填电谷，是消纳“三北”地区弃风的主要途径之一。对比分析源侧集中式与荷侧分布式配置电锅炉的弃风消纳效果。首先在机理上从热网衰减对热源供热功率影响、热网延时对热电机组供热功率影响、热网延时对电锅炉供热功率和填谷效果的影响三个方面分析了两种电锅炉配置方式的消纳弃风效果的异同。然后分别构建了两种电锅炉配置方式的电热联合系统的调度模型。通过实例仿真分析，证明了荷侧分布配置方案的热网总损耗更小，热电机组供热功率和“以热定电”功率更小，电锅炉的填谷效果更好，弃风消纳效果更佳。 |

| Abstract: |
| Configuration of electric boilers to cut heat load peak and fill power load valley is one of the main ways to reduce wind power abandoning in Northeast, North, and Northwest China. This paper compares and analyses the effect of centralized source-side and distributed load-side electric boilers on wind power curtailment. Firstly, from three aspects of the influence of heat network loss on heat power of heat source, and the influence of heat network delay on heat power of thermoelectric unit, on heat power and on effect of filling power load valley of electric boilers, the similarities and differences of wind power curtailment effect between two different electric boiler configurations are analyzed on mechanism. Then, the dispatching models of the combined heat and power system of two different electric boiler configurations are constructed respectively. Results of case simulation show that the configuration of distributed load-side electric boilers has lower total heat loss, lower heat power and power determined by heat of thermoelectric units, better effect of filling power load valley by electric boilers, and better effect of wind power curtailment.
