摘要
大规模风电接入给电力系统运行带来很大不确定性,增加了系统发电调度和备用决策的难度。深入分析了大规模风电接入电力系统备用决策的影响因素。在传统确定性决策方法的基础上,重点梳理和对比计及风电影响的概率性决策方法,指出各类方法的特点及可能存在的问题。从电源侧和需求侧两个方面深入探讨了大规模风电接入电力系统的备用配置问题,指出风、火等多电源打捆和电动汽车等储能设备以及其他技术在解决备用配置问题中的应用潜力。综合大规模风电接入对电力系统生产、运行以及消费环节的影响,对传统的电力系统备用的概念进行了扩展。
With large scale wind power integration, system operators are now facing more uncertain factors in power dispatch and reserve decision. This paper analyzes the influencing factors in power reserve decision. Deterministic and probabilistic methods of reserve decision are summarized, especially their differences and characteristics. The problem of reserve configuration can be achieved both from demand side and power supply side with some feasible options such as the combination of wind and thermal power, electric vehicles and other energy storages. Considering the influence of power system production, operation, and consumption comprehensively with large scale wind power integration, the general concept of power reserve is extended based on all the above.
