【摘要】：為促進(jìn)節(jié)能減排,擴(kuò)大系統(tǒng)對(duì)可再生能源的接納,可通過負(fù)荷調(diào)度將負(fù)荷側(cè)可調(diào)節(jié)資源常態(tài)化地納入到電力系統(tǒng)調(diào)度運(yùn)行中。文章研究將需求側(cè)資源進(jìn)行虛擬機(jī)組建模的方法,分析虛擬機(jī)組的成本特性及負(fù)荷調(diào)度對(duì)參與方的經(jīng)濟(jì)利益影響,同時(shí)分析了負(fù)荷的物理特性以及作為虛擬機(jī)組需要遵循的約束。在此基礎(chǔ)上,建立節(jié)能發(fā)電調(diào)度模式下的日前負(fù)荷調(diào)度模型,通過日前小時(shí)電價(jià)調(diào)用小時(shí)響應(yīng)負(fù)荷和日內(nèi)可轉(zhuǎn)移負(fù)荷,以更少的發(fā)電成本實(shí)現(xiàn)電力行業(yè)更高層次的節(jié)能減排,最后通過對(duì)負(fù)荷調(diào)度結(jié)果的還原將虛擬機(jī)組出力轉(zhuǎn)換為實(shí)際負(fù)荷值。算例表明所建立的日前負(fù)荷調(diào)度模型可方便地進(jìn)行負(fù)荷調(diào)度,有效降低煤耗和污染物排放,并達(dá)到較好的削峰填谷效果。
[Abstract]:In order to promote energy saving and emission reduction and expand the system's acceptance of renewable energy, load side adjustable resources can be regularized into power system dispatching operation through load dispatching. In this paper, the method of modeling the virtual machine group with demand-side resources is studied, and the cost characteristics of the virtual machine group and the impact of load scheduling on the economic benefits of the participants are analyzed. At the same time, the physical characteristics of the load and the constraints to be followed as a virtual machine group are analyzed. On this basis, the pre-day load dispatching model under the mode of energy-saving generation dispatching is established, which calls the hourly response load and intra-day transferable load through the electricity price before the day, so as to achieve the higher level of energy saving and emission reduction in the power industry with less generation cost. Finally, the virtual machine group output is converted to the actual load value by restoring the load scheduling results. The example shows that the pre-day load dispatching model is convenient for load dispatching, which can effectively reduce coal consumption and pollutant emission, and achieve a better effect of peak cutting and valley filling.
