【摘要】:分散式的電采暖負(fù)荷是一種典型的熱儲(chǔ)能設(shè)備,功率較大,電能產(chǎn)出的熱量具有滯后性和存儲(chǔ)性,現(xiàn)有運(yùn)行方式單一且僅針對(duì)單個(gè)設(shè)備,無法實(shí)現(xiàn)區(qū)域范圍內(nèi)電采暖負(fù)荷的協(xié)同優(yōu)化。針對(duì)上述問題,文中首先提出了智能電暖網(wǎng)絡(luò)的概念、架構(gòu)以及衡量該網(wǎng)絡(luò)運(yùn)行效果的優(yōu)化指標(biāo)。其次,提出了智能電暖網(wǎng)絡(luò)的確定性優(yōu)化運(yùn)行模型,該模型首先在保證最大功率限制的約束下,求解可達(dá)到的最大舒適度;再將最大的舒適度作為約束,尋求使運(yùn)行電費(fèi)最小化的運(yùn)行策略。進(jìn)而,在等效熱參數(shù)模型的基礎(chǔ)上引入溫度波動(dòng)不確定量,構(gòu)建了確定性模型對(duì)應(yīng)的魯棒優(yōu)化模型。算例分析表明,相比現(xiàn)有的實(shí)時(shí)溫控策略,確定性優(yōu)化策略可有效控制尖峰負(fù)荷,明顯提高溫度效用,降低運(yùn)行電費(fèi);魯棒優(yōu)化策略比確定性優(yōu)化策略更好地保證了用戶舒適度,但運(yùn)行電費(fèi)略有升高。所提優(yōu)化策略充分響應(yīng)峰谷電價(jià),在實(shí)現(xiàn)經(jīng)濟(jì)運(yùn)行的同時(shí),可以間接響應(yīng)電網(wǎng)削峰填谷。
[Abstract]:Distributed electric heating load is a kind of typical thermal energy storage equipment, which has a large power, and the heat produced by electric energy has hysteresis and storage. The current operation mode is single and only for a single device. The cooperative optimization of electric heating load in the area can not be realized. Aiming at the above problems, the concept, architecture and optimization index of the intelligent electric heating network are put forward in this paper. Secondly, the optimization index of the network operation effect is put forward. The deterministic optimal operation model of intelligent electric heating network is proposed. Firstly, under the constraint of the maximum power limit, the maximum comfort can be obtained. Then the maximum comfort is taken as the constraint to find the operation strategy to minimize the electricity cost. Furthermore, the uncertainty of temperature fluctuation is introduced on the basis of the equivalent thermal parameter model. The robust optimization model corresponding to the deterministic model is constructed. The example analysis shows that the deterministic optimization strategy can effectively control the peak load, improve the temperature utility and reduce the running electricity cost compared with the existing real-time temperature control strategy. The robust optimization strategy is better than the deterministic optimization strategy to ensure the comfort of the user, but the electricity cost is slightly higher. The proposed optimization strategy fully responds to the peak and valley price, and realizes the economic operation at the same time. It can indirectly respond to the peak of the grid and fill the valley.
