【摘要】：應(yīng)對(duì)風(fēng)電消納問(wèn)題,價(jià)格型需求響應(yīng)通過(guò)價(jià)格信號(hào)參與電網(wǎng)實(shí)時(shí)調(diào)度,以保持電力供需平衡。然而,風(fēng)電出力和負(fù)荷的改變,使電網(wǎng)潮流和節(jié)點(diǎn)電壓面臨越限風(fēng)險(xiǎn),從而網(wǎng)絡(luò)安全約束成為制約風(fēng)電消納的關(guān)鍵因素。首先基于價(jià)格彈性系數(shù)分析價(jià)格型需求響應(yīng)調(diào)度成本與互動(dòng)響應(yīng)量之間的關(guān)系。其次,描述價(jià)格型需求響應(yīng)的互動(dòng)響應(yīng)量靜態(tài)算法,并將其作為預(yù)期分配原則之一。在此基礎(chǔ)上,同時(shí)考慮網(wǎng)絡(luò)安全約束和價(jià)格型需求響應(yīng)互動(dòng)響應(yīng)滿意度約束,以電網(wǎng)側(cè)的價(jià)格型需求響應(yīng)調(diào)度成本最小化為目標(biāo),建立實(shí)時(shí)優(yōu)化調(diào)度模型,保證實(shí)時(shí)調(diào)度中電網(wǎng)的安全運(yùn)行。應(yīng)用靈敏度分析方法將網(wǎng)絡(luò)安全約束轉(zhuǎn)化為負(fù)荷節(jié)點(diǎn)互動(dòng)響應(yīng)量約束,并通過(guò)內(nèi)點(diǎn)法求解模型。最后,以某省實(shí)際電網(wǎng)為例分析驗(yàn)證建模和求解的有效性和可行性,結(jié)果表明通過(guò)價(jià)格型需求響應(yīng)消納風(fēng)電的同時(shí)可將穩(wěn)定斷面有功功率控制在允許范圍內(nèi)。
[Abstract]:In order to maintain the balance of power supply and demand, price type demand response participates in real time dispatching of power grid through price signal. However, wind power output and load change. The power flow and node voltage of the power network are exposed to the risk of exceeding the limit. Therefore, network security constraints become the key factor to restrict wind power consumption. Firstly, based on the price elasticity coefficient, the relationship between the cost of price demand response scheduling and the interaction response is analyzed. This paper describes the static algorithm of interactive response to price-based demand response, and takes it as one of the expected allocation principles. On this basis, we consider the network security constraints and the price demand response interactive response satisfaction constraints at the same time. Aiming at minimizing the cost of price-based demand response scheduling on power grid side, a real-time optimal scheduling model is established. In order to ensure the safe operation of the power network in real-time dispatching, the security constraints of the network are transformed into the interactive response constraints of load nodes by using the sensitivity analysis method, and the model is solved by the interior point method. Finally. The validity and feasibility of modeling and solving are verified by taking the actual power grid of a province as an example. The results show that the active power of the stable section can be controlled within the allowable range by the price type demand response to absorb wind power at the same time.
