摘要
结合多种储能方式的建筑供能系统已成为减少建筑能耗、提高可再生能源利用率和用户负荷满足率的有效途径。构建一种融合光伏、储电、储氢的多元储能供能系统,提出适配该系统的能量管理策略。以严寒地区超低能耗住宅为研究对象,通过Trnsys模拟计算住宅全年逐时冷热电负荷,并建立多种供能系统仿真模型,对比分析不同供能系统案例的弃光量和负荷不满足率。结果表明,光储氢系统可以有效削峰填谷,能够满足光伏与蓄电池电能不足时的用户负荷需求。相较于光伏系统和光储系统,光储氢系统的弃光量减少了93.50%和77.73%,负荷不满足率减少了68.08%和36.49%。通过模拟分析光储氢系统夏季、冬季典型日的能量供需平衡,进一步表明了系统的可行性,为严寒地区超低能耗建筑的供能系统优化提供了参考。
Building energy supply systems that integrate multiple energy storage methods have become an effective way to reduce building energy consumption,improve the utilization rate of renewable energy and the load satisfaction rate of users.Construct a multi-energy storage and supply system integrating photovoltaic,electricity storage and hydrogen storage,and propose an energy management strategy suitable for this system.Taking ultra-low energy consumption residences in extremely cold regions as the research object,the hourly cooling,heating and power loads of the residences throughout the year are simulated and calculated through Trnsys,and multiple simulation models of energy supply systems are established.The amount of abandoned light and the load non-compliance rate of different energy supply system cases are compared and analyzed.The results show that the photovoltaic energy storage and hydrogen system can effectively reduce peak loads and fill valleys,and can meet the load demands of users when the power of photovoltaic and battery is insufficient.Compared with the photovoltaic system and the photovoltaic storage system,the photovoltaic hydrogen storage system has reduced the amount of abandoned light by 93.50%and 77.73%,respectively,and the load non-compliance rate has decreased by 68.08%and 36.49%,respectively.The feasibility of the system is further demonstrated by simulating and analyzing the energy supply and demand balance of the photovoltaic hydrogen storage system on typical days in summer and winter.It provides a reference for the optimization of the energy supply system of ultra-low energy consumption buildings in extremely cold regions.
