摘要
针对储能系统如何配合电网高效消纳风电的问题,基于计及储能系统的风电最大接纳调度模式和风电经济接纳调度模式,建立了相应的数学模型和求解方法。以此为基础分析了两种接纳模式在不同风电渗透率和不同储能容量场景下的风电接纳能力及系统经济性,重点分析了储能装置对系统风电接纳能力的影响以及经济弃风产生的原因。通过10机系统算例分析,表明调峰容量比对系统接纳风电能力有着较大影响,储能系统可明显地提高系统接纳风电的能力,但在经济接纳模式下储能装置的引入并不一定能减少系统弃风。
As for the coordination between energy storage system（ESS） and power grid for efficient wind power access,this paper proposes the corresponding mathematical model and solutions based on the scheduling model for maximum wind power access and that for economical wind power access considering ESS.Then it analyzes the wind power integration capacity and system economy under different scenarios of wind power penetration and storage capacity in these two modes,and emphatically,the effects of ESS on the wind power integration capacity of the power system,as well as the reasons for economically-abandoned wind.As indicated in the case study of 10-unit system,the peaking capacity has a greater impact on the wind power integration capacity;the ESS can significantly improve the integration capacity;however,the introduction of the energy storage device does not necessarily reduce the abandoned wind in the economical-access mode.
