ZEH是目前日本低碳示范项目的主要实践之一。广泛实施HEMS的ZEH预计将提供能源和成本节约的机会，并在合作设计的电力定价计划下更多地发挥生产者的作用。本研究的重点是调查日本真实的ZEH应用的技术经济性能。首先，我们介绍了当前的技术创新和协调智能管理策略，以优化ZEH的成本或节能性能。然后，我们说明了四个典型的ZEH的运行性能，重点是自给自足的功率和动态功率平衡。与此同时，我们根据历史数据研究了HEMS在管理综合现场发电机方面的作用。结果表明，提前预测有助于提高日耗热量与热泵预生产量的匹配性，燃料电池能有效应对同时发生的电力和供热负荷变化，热电联产系统能提高当地电力自给率，减少净负荷波动，尤其是在高供热需求时期。我们还得出结论，ZEH的高效性能不仅是先进技术的问题，而且还高度依赖于实时需求侧管理和本地负载匹配方案。最后，我们分析和比较的影响，综合现场发电机之间的ZEH提高经济和环境性能，从整体能源系统。分析表明，光伏发电对ZEH的年度经济效益贡献很大。燃料电池在降低CO2年排放量方面具有优势.

ZEHs are one of the main practices in current Japanese low carbon demonstration projects. ZEHs with wide implementation of HEMS are expected to provide energy and cost-saving chances and are playing more as prosumers under collaboratively designed power-pricing schemes. This research focused on investigating the techno-economic performance of real ZEH applications in Japan. Firstly, we introduced the current technological innovations and coordinated smart management strategies to optimize the cost or energy-saving performance of the ZEHs. Then, we illustrated the operational performances of four typical ZEHs focused on the power of self-sufficiency and dynamic power balance. Meanwhile, we examined the role of HEMS in managing integrated on-site generators based on how they operated according to historical data. Results indicated that day-ahead prediction helped enhance the matching scenario between daily thermal consumption and preproduction of heat pumps, fuel cells could respond effectively to changes in simultaneous electricity and heating loads, and cogeneration systems could enhance the local electricity self-sufficiency ratio and reduce net load fluctuations, especially under high heating demand periods. We also concluded that efficient performance of ZEHs is not just a matter of advanced technologies but is also highly dependent on real-time demand-side management and local load-matching scenarios. Finally, we analyzed and compared the impacts of integrated on-site generators among ZEHs on improving economic and environmental performance from an overall energy system. The analysis indicated that PV contributed to a significant ratio of annual ZEH's economic profit. Fuel cells presented an advantage in reducing annual CO 2 emission. (C) 2020 Elsevier B.V.
