摘要
在综合能源系统向复杂化、高耦合度发展的过程中,设备单元运行可靠性降低与高昂的设备运维成本问题难以忽视.针对上述问题,从内部配置结构优化的角度,将系统工程中主、被动冗余思路引入综合能源系统,完成子系统单元的冗余设计.提出了一种针对冗余设备逻辑最优工况匹配的两阶段流程,以实现全系统整年运行优化.从经济、能源和环境 3 方面建立评价指标,基于蜜獾算法对两建筑、四系统进行案例研究.结果表明:所提 3种冗余系统均实现了可靠性与各性能指标的明显提升;主动冗余系统年度总运行成本最低,热备用系统可靠性表现最好,冷备用系统综合性能最佳.
Abstract
During the development of comprehensive energy system towards complexity and high coupling,the reduced operational reliability of equipment units and high equipment operation and maintenance costs are hard to ignore.In view of the above problems,from the perspective of internal configuration structure optimization,the idea of active and passive redundancy in system engineering was introduced into the integrated energy system to complete the redundancy design of subsystems.A two-stage optimization process was proposed to achieve the logical optimal working condition matching of the redundant equipment and the whole system process.Evaluation indexes were established from economic,energy and environmental aspects,and case studies were conducted for two buildings and four systems based on the honey badger algorithm.The results showed that all three redundancy design options bring significant improvements in system reliability and performance indicators;the active redundancy system had the lowest total annual operating cost,the hot standby system had the best reliability performance,and the cold standby system had the best overall performance.
