【摘要】：目前基于能量樞紐(energy hub,EH)的區(qū)域綜合能源系統(tǒng)的優(yōu)化運(yùn)行缺乏對(duì)EH內(nèi)熱電聯(lián)產(chǎn)(combined heat and power,CHP)機(jī)組熱電比可調(diào)的考慮,且在此類場(chǎng)景中參與需求側(cè)響應(yīng)的負(fù)荷種類單一。針對(duì)此狀況,構(gòu)建雙層優(yōu)化模型,建立EH機(jī)組內(nèi)部能效特性與外部能源分配的聯(lián)系,實(shí)現(xiàn)內(nèi)部機(jī)組高效運(yùn)行和外部能源經(jīng)濟(jì)分配。模型通過卡羅需-庫(kù)恩-塔克條件(Karush-Kuhn-Tucker Conditions,KKT)將雙層優(yōu)化轉(zhuǎn)換為單層優(yōu)化,并用確定性優(yōu)化軟件求解。算例結(jié)果表明,EH雙層優(yōu)化運(yùn)行模型可減少用能成本,提高用能效率。通過調(diào)節(jié)CHP熱電比,同時(shí)利用廣義彈性負(fù)荷參與響應(yīng),可以減小CHP熱電比與區(qū)域內(nèi)熱電負(fù)荷比之間差距,從而提高CHP供能比例,實(shí)現(xiàn)區(qū)域綜合能源系統(tǒng)高效經(jīng)濟(jì)運(yùn)行。
[Abstract]:At present, the optimal operation of regional integrated energy system based on energy hub energy hub (EH) lacks the consideration that the heat and power ratio of combined heat and power CHP units in EH can be adjusted, and there is a single type of load involved in the demand-side response in this kind of scenario.In view of this situation, a double-layer optimization model is constructed to establish the relationship between the internal energy efficiency characteristics of EH units and the external energy distribution, and to realize the efficient operation of the internal units and the external energy economic distribution.By Karush-Kuhn-Tucker conditions KKT (Karush-Kuhn-Tucker ConditionsKKT), the two-layer optimization is transformed into single-layer optimization and solved by deterministic optimization software.The results show that the two-layer optimal operation model of EH can reduce the cost of energy use and improve the efficiency of energy use.By adjusting the CHP thermoelectric ratio and using generalized elastic load to participate in the response, the gap between the CHP thermoelectric ratio and the thermoelectric load ratio in the region can be reduced, thus increasing the ratio of CHP energy supply and realizing the efficient and economical operation of the regional integrated energy system.
