摘要
综合能源系统有利于实现多能互济、能源高效利用。以含电、热、冷、氢负荷的园区综合能源系统为研究对象,分析了可再生能源制氢系统及掺氢燃气轮机运行中多种能源的耦合及梯级利用特性,考虑了掺氢比对燃气轮机效率以及热电比的影响,以系统运行成本最小为目标函数,建立了阶梯式碳交易机制下的园区综合能源系统优化调度模型。采用分段线性化和大M法将包含多个0–1变量和连续变量的非线性模型转化为混合整数规划模型,并调用Cplex求解器实现快速求解。算例分析表明,所提调度策略可有效提高园区能源系统运行经济性,合理调控燃气轮机掺氢比有利于降低园区系统的碳排放。
The integrated energy system is conducive to the realization of multi-energy mutual benefit and efficient use of energy.This paper focuses on a comprehensive energy system in a park that incorporates electricity,heat,cold,and hydrogen loads.The study analyzes the coupling and cascade utilization characteristics of multiple energy sources in the operation of a renewable energy hydrogen production system and hydrogen-blended gas turbine.The impact of hydrogen blending ratio on gas turbine efficiency and the thermoelectric ratio is considered.With the objective of minimizing the operational cost of the system,an optimization and dispatching model for the park’s comprehensive energy system is established under a tiered carbon trading mechanism.Segmented linearization and the big M method are employed to transform a nonlinear model containing multiple 0-1 variables and continuous variables into a mixed-integer programming model.The model is then solved using the Cplex solver to achieve fast solutions.Case analysis shows that the dispatching strategy designed in this paper can effectively improve the economic performance of the park’s energy system.Properly controlling the hydrogen blending ratio in gas turbine helps reduce carbon emission in the park’s system.
