100%可再生能源综合能源系统容量优化配置

Capacity Optimal Allocation of Integrated Energy System Consisting of 100% Renewable Energy

为实现100%可再生能源综合能源系统的安全稳定运行,合理的容量配置至关重要。首先,考虑氢能的利用特性,构建电热氢多能耦合的综合能源系统。其次,以运行成本最低和污染物排放量最小为目标,建立一种100%可再生能源综合能源系统的容量优化配置模型,并采用折衷规划和模糊方法构造Pareto前沿对多目标问题进行求解。最后,基于3个不同季节典型日风光出力和电、热、氢负荷特性曲线,通过仿真算例验证所建模型的有效性,并证明氢能的应用能为综合能源系统带来明显的经济效益。

In order to realize the safe and stable operation of the 100%renewable energy integrated energy system,reasonable capacity allocation is very important.Firstly,considering the utilization characteristics of hydrogen energy,an integrated energy system with multi-energy coupling of electricity,heat and hydrogen was constructed.Secondly,aiming at the lowest operating cost and minimum pollutant emission,a capacity optimal allocation model of a integrated energy system with 100%renewable energy was established,and the Pareto frontier was constructed by the compromise planning and fuzzy method to solve the multi-objective problem.Finally,based on the characteristic curves of typical diurnal output and electric,thermal and hydrogen loads in three different seasons,the validity of the model is verified by simulation examples,and the application of hydrogen energy can bring obvious economic benefits to the integrated energy system.
