摘要: |
目前,世界各国正处于清洁能源转型发展的关键时刻。未来,随着风电比例的增加,以功率调节为主的储能技术将难以满足高比例风电渗透下长时间尺度的系统需求,亟需统筹优化短时功率和长期能量的双重调节。在源-储-输联合规划模型的基础上,考虑长短期储能的相互配合,提出了以系统综合成本最小化为目标的优化模型。结合负荷数据刻画不同风速变化的极端场景,重点对比分析了不同风荷匹配类型下源-储-输的规划结果。算例结果表明,在新型电力系统的发展过程中,所提联合优化模型能提高电网整体的经济效益,对推动“双碳”目标的实现具有重要的意义。 |

Abstract: |
At present, countries all over the world are at a critical juncture in the transformation and development of clean energy. In the future, with the increase of the proportion of wind power, energy storage technology based on power regulation will be difficult to meet the long-term scale system requirements under the high proportion of wind power penetration, so it is urgent to optimize the dual regulation of short-term power and long-term energy. Based on the joint planning model of source-storage-transportation, considering the cooperation of long-and short-term energy storage, an optimization model is proposed to minimize the system comprehensive cost. Combined with the load data, the extreme scenarios of different wind speed changes are described, and the planning results of source-storage-transportation under different wind-load matching types are mainly compared and analyzed. The example results show that the proposed joint optimization model can improve the overall economic benefits of the power grid in the development process of the new-type power system, which is of great significance to promote the realization of the dual carbon target. |
