摘要:
针对含分布式变速抽水蓄能和多灵活性资源的新能源发电系统,在分析定、变速抽水蓄能运行特性差异的基础上,提出含分布式变速抽水蓄能的灵活性资源规划模型。该模型详细考虑了定、变速抽水蓄能的运行约束和库容约束,以及电池储能、需求响应、火电机组资源配置。通过松弛变速抽水蓄能的双线性约束,将所建立模型转化为以期望成本最小为目标的混合整数线性规划问题,通过两阶段随机优化方法求解得到最优的规划方案。通过与定速抽水蓄能规划方案对比,分析验证了所提分布式变速抽水蓄能规划方案的可行性以及在经济性和灵活性方面的优越性。

Abstract:
Aiming at the renewable generation systems with distributed variable speed pumped storages and multiple flexible resources, based on the analysis of the operation characteristics of fixed and variable speed pumped storages, a flexible resource planning model with distributed variable speed pumped storages is proposed. The model not only considers the operation and capacity constraints of fixed and variable speed pumped storages, but also considers the resource allocation of battery energy storages, demand response and thermal power units. By relaxing the bilinear constraints of variable speed pumped storages, the established model is transformed into a mixed integer linear programming problem with the objective of minimizing the expected cost, which is solved with a two-stage stochastic optimal method to obtain the optimization planning scheme. By comparing with the fixed speed pumped storage planning scheme, it is verified that the proposed planning scheme of distributed variable speed pumped storages has the feasibility and superiority on system economic and flexibility.
Key words:  renewable energy  flexible resource planning  pumped storage  distributed variable speed pumped storages
