    摘 要:充分考慮工業(yè)園區(qū)用能、降碳需求,結(jié)合不同能源轉(zhuǎn)換的耦合關(guān)系及設(shè)備運行特點,對園區(qū)典型設(shè)備進行建模,并采取合適的約束條件進行安全管控;引入碳排放成本精確計算方法,結(jié)合碳排放分配額量化碳交易成本,以經(jīng)濟性、低碳性為目標,提出園區(qū)綜合能源系統(tǒng)運行優(yōu)化方法。以某工業(yè)園區(qū)為算例,在 MATLAB 環(huán)境下使用 Yalmip 語法編程并調(diào)用 Gurobi 求解器求解,將所建立的非線性模型轉(zhuǎn)換為易于求解的 MILP 問題,并對子系統(tǒng)分立運行以及綜合能源系統(tǒng)優(yōu)化運行兩種場景下的結(jié)果進行對比分析。結(jié)果表明,構(gòu)建基于碳交易的園區(qū)綜合能源系統(tǒng)及進行優(yōu)化方法對實現(xiàn)節(jié)能減碳、降低成本有著顯著效果。

    Abstract: The paper, considering the needs of energy consumption and carbon reduction in industrial parks, builds models of typical equipments according to the coupling relationships of different energy conversion and the characteristics of equipment operation, and adopts appropriate constraints for safety management and control. Then, it introduces an accurate method of calculating carbon emission costs,quantifies the carbon transaction cost according to carbon emission allocation, and proposes an optimization method for the park comprehensive energy system operation. Third, the paper, taking an industrial park as an example, adopts Yalmip syntax programming and Gurobi solver in the MATLAB environment. It transforms the established nonlinear model into an easy-to-solve MILP problem, and makes comparative analysis of the subsystem separate operation and the comprehensive energy system optimal operation. The results show that the construction of an integrated energy system in the park based on carbon trading and relevant optimal methods have great effects on energy saving, carbon reduction, and cost reduction.
    Key words: carbon trading; park integrated energy system; cooling-heat-electricity-gas subsystem; mixed integer nonlinear programming
