摘要: |
风火打捆送出是提高风电消纳能力的重要方式,其难点之一在于整定打捆的最优风火容量配比。提出了基于时序运行模拟的风火打捆容量最优配比整定方法。首先,通过气象数据获取规划中风电的全年出力特性。然后,以机组总运行成本最低及清洁能源消纳率最高为目标,建立小时级时序运行模拟模型,采用时序分解及自动回滚技术实现模型的快速求解。此外,针对为期一年的模拟结果,进一步利用暂态稳定约束进行校核与调整,消除潜在的暂稳风险。最后,以广东电网珠西北地区为例,通过对比不同风火配比下的风电消纳能力及运行经济性数据,给出了兼顾环保性、安全性与经济性的风火配比。运行结果可为地区的海上风电规划与建设、电力系统调度提供指导。

Abstract: |
Wind-thermal bundled transmission is considered an important way to promote wind power accommodation. One of the difficulties lies in setting the optimal bundled wind-thermal capacity ratio. This paper proposes a method for setting the optimal ratio based on chronological operation simulation. First, the annual output characteristics of the planned wind power are obtained through meteorological data. Then, an hourly chronological operation simulation model is established, aiming at the lowest total operating cost of the system and the highest clean energy accommodation rate. The simulation model is analysed with time domain partitioning and a rollback mechanism to accelerate the computation speed. One-year hourly simulation results are further checked and adjusted to avoid potential transient stability risks. Finally, taking the Northwest region of Guangdong Power Grid as an example, by comparing the wind power accommodation capacity and operating economic data under different wind-thermal ratios, the optimal setting of the wind-thermal-bundled capacity ratio is recommended considering the effects of environmental protection, safety and economy. The results of the simulation can provide guidance for the planning and construction of offshore wind power and power system dispatch.
