【摘要】：電力系統(tǒng)靈活性是系統(tǒng)響應(yīng)負(fù)荷功率和(或)波動(dòng)電源功率變化而隨之調(diào)節(jié)的能力,主要是15min-1h時(shí)間尺度內(nèi)系統(tǒng)功率調(diào)節(jié)能力,表征了系統(tǒng)在調(diào)度周期內(nèi)調(diào)節(jié)資源的充裕性,取決于電源功率調(diào)節(jié)特性和負(fù)荷需求響應(yīng)特性(由于目前缺乏有效的需求響應(yīng)激勵(lì)機(jī)制,系統(tǒng)靈活性主要取決于電源的功率調(diào)節(jié)特性)。傳統(tǒng)的機(jī)組組合編制方法通�；陔娏ζ胶忪o態(tài)約束,忽視了機(jī)組調(diào)節(jié)性能的差異性,可能會(huì)導(dǎo)致所制定的機(jī)組組合方式不能適應(yīng)可再生能源功率的波動(dòng),進(jìn)而造成棄風(fēng)棄光現(xiàn)象。因此,就需要結(jié)合負(fù)荷、可再生能源的波動(dòng)特性,對(duì)調(diào)度周期內(nèi)系統(tǒng)調(diào)節(jié)資源的充裕性進(jìn)行量化評(píng)估,指導(dǎo)調(diào)度運(yùn)行人員根據(jù)不同的運(yùn)行情況合理安排靈活調(diào)節(jié)資源。本文圍繞電力系統(tǒng)靈活性的定義,針對(duì)系統(tǒng)內(nèi)多種資源在靈活性方面的供給及消耗情況進(jìn)行了量化分析。由于考慮到當(dāng)前高比例可再生能源滲透系統(tǒng)在跟蹤負(fù)荷波動(dòng)過(guò)程中主要困難為功率調(diào)節(jié)范圍不足,因此本文選擇將調(diào)節(jié)范圍作為靈活性的量化指標(biāo)。分析了網(wǎng)絡(luò)約束對(duì)系統(tǒng)靈活性傳輸情況的影響,定義了靈活性判定矩陣,通過(guò)對(duì)各分區(qū)凈靈活性與網(wǎng)絡(luò)功率傳輸限制的判定,得到考慮網(wǎng)絡(luò)約束下的系統(tǒng)靈活性充裕度情況。基于對(duì)系統(tǒng)靈活性充裕度的分析,提出了應(yīng)用于開(kāi)機(jī)方式制定階段的可再生能源消納能力評(píng)估方法。本方法能夠針對(duì)特定開(kāi)機(jī)方式下各時(shí)段系統(tǒng)靈活調(diào)節(jié)能力、可再生能源消納情況以及造成棄風(fēng)棄光的原因進(jìn)行分析,并能夠輔助調(diào)度運(yùn)行人員根據(jù)一定的可再生能源消納指標(biāo)調(diào)整系統(tǒng)內(nèi)的靈活調(diào)節(jié)資源。不同場(chǎng)景下的運(yùn)行約束將一定程度上限制儲(chǔ)能裝置及電加熱負(fù)荷靈活調(diào)節(jié)能力的展現(xiàn)。本文針特定的場(chǎng)景下,不同裝置參數(shù)下所能對(duì)電力系統(tǒng)靈活性的提升情況進(jìn)行了分析。最后,基于上述理論研究并結(jié)合實(shí)際運(yùn)行需求,研發(fā)了系統(tǒng)靈活性評(píng)估軟件。
[Abstract]:Power system flexibility is the ability of power system to adjust in response to changes in load power and / or fluctuating power supply, mainly in the 15min-1h time scale. The adequacy of regulating resources in the scheduling cycle is characterized by the characteristics of power supply regulation and load demand response (due to the lack of an effective demand response incentive mechanism at present). The flexibility of the system mainly depends on the power regulation characteristics of the power supply. The traditional method of generating unit configuration is usually based on the static constraints of power balance and neglects the difference of the unit regulation performance. It may result in the unit combination mode can not adapt to the fluctuation of renewable energy power, and then cause the phenomenon of abandoned wind and light. Therefore, it is necessary to combine the load, the fluctuation characteristics of renewable energy. This paper evaluates the adequacy of the system regulation resources in the dispatching cycle and instructs the dispatching operators to arrange the flexible adjustment resources according to different operation conditions. This paper focuses on the definition of power system flexibility. The supply and consumption of various resources in the system in terms of flexibility are analyzed quantitatively. Considering that the main difficulty in tracking load fluctuation in the current high proportion renewable energy permeation system is the power regulation norm. Inadequate perimeter. Therefore, this paper chooses the adjustment range as the quantitative index of flexibility, analyzes the influence of network constraints on the flexible transmission of the system, and defines the flexibility decision matrix. By judging the net flexibility of each partition and the network power transmission limit, the system flexibility adequacy under the network constraints is obtained. The analysis of the system flexibility adequacy is based on the analysis of the system flexibility adequacy. An evaluation method of renewable energy absorption capacity is proposed, which is applied to the development stage of startup mode. This method can flexibly adjust the capacity of the system in each period of time under a specific start-up mode. The situation of renewable energy consumption and the causes of wind abandonment and light loss are analyzed. The flexible adjustment resources in the system can be adjusted according to certain renewable energy consumption index. The operation constraints under different scenarios will limit the flexible adjustment of energy storage device and electric heating load to a certain extent. Ability to demonstrate. This article needle specific scene. The flexibility of power system is analyzed under different device parameters. Finally, the system flexibility evaluation software is developed based on the above theoretical research and practical operation requirements.
