摘要
近年来,风储联合发电系统取得了一定的发展,但在网络约束下的储能系统储放范围与风电渗透率之间存在着制约的关系,导致原有调峰资源的配置方案会对储能系统的储放空间及运行效率产生一定的影响。为解决该问题,文章引入风储联合系统接入配网后的多维运行边界并将其转化为调峰资源优化配置过程中的约束条件,建立综合考虑风储容量与调峰资源经济性的优化配置模型并进行求解。仿真算例验证结果表明,文章提出的考虑风储多维运行边界下调峰优化配置模型可实现风电与储能利用最大化及调峰资源配置经济性最优。
With the development of hybrid Wind-ES power system,there is a restriction between the storage range of energy storage system and the permeability of wind power under the restriction of network.As a result,the the original peak shaving resources configuration plan will have certain limitations on the storage space and operation efficiency of the energy storage system.In this paper,the multi-dimensional operation boundary of hybrid Wind-ES power system after access to the distribution network is introduced and transformed into the constraints in the process of optimal allocation of peak shaving resources.An optimal allocation model consider-ing the capacity of wind storage and the economy of peak shaving resources is established and solved.Finally,a simulation is given to verify that the optimal configuration model of peak load regulation considering the hybrid Wind-ES power system multi-dimensional operation boundary can maximize the utilization of wind power and energy storage and achieve economic optimization.
