摘要
为减少高耗能机组出力,同时增加风电消纳能力,考虑负荷和储能两类灵活调用资源,提出基于荷-储碳放流模型的电力系统双层经济低碳优化调度方法.基于电力系统碳排放流理论,分别建立负荷和储能设备的碳排放流模型;设计考虑荷-储协同优化的低碳调度策略,在负荷侧建立基于负荷节点碳势的电-碳耦合价格需求响应模型,同时鉴于荷侧降碳调节的局限性,在储能侧建立基于碳流模型的低碳调度策略,实现荷-储协同低碳调度策略;考虑经济性和低碳性,建立包含上层经济调度、下层低碳调度的双层优化调度模型.通过改进IEEE-14节点系统对优化调度方法进行仿真验证,结果表明:提出的优化调度方法在保证经济性的同时,减少了弃风,并降低了高耗能机组出力,从而有效降低了全系统的碳排放.
Abstract
In order to reduce the output of high energy consuming units on the power generation side,increase the absorption capacity of wind power,and consider the flexible resource allocation such as load and energy storage,a two-level economic low-carbon optimal scheduling method for power systems based on a carbon storage and discharge model is proposed.Based on the carbon emission flow theory of power system,a model for load and energy storage equipment is established;A demand response model based on the electricity carbon coupling price is established on the load side,and in view of the limitation on the load side,a low-carbon scheduling strategy based on the carbon flow model for energy storage is established to realize a coordinated low-carbon scheduling strategy for load storage.Considering the economy and low carbon,a two-level optimal scheduling model including upper economic scheduling and lower low-carbon scheduling is established.Simulation on an improved IEEE-14 bus system show that the proposed optimal scheduling method can reduce the wind abandonment,promote the replacement of high energy consumption units,and effectively reduce carbon emissions while ensuring the economy.
