楼宇智能微网采用一个多输入直流变换器，代替多个单输入直流变换器，实现风光水储能量汇集，简化电路，降低成本，提高能源综合利用率。它优先利用分布式能源，并能根据大电网动态引导电价移峰填谷，降低楼宇总电费，还利用储能装置和抽水储能赚取电网峰谷差价。多种分布式能源单独/同时连续供给负荷，增加新能源消纳能力，提高自动需求响应的快速性、可靠性和灵活性。小功率仿真实验验证了多源能量汇集的可行性和混合供电系统的稳定性。

Research of Comprehensive Energy Management for Multi-resource in Wind-PV-Water Storage Power System Based on Dynamic Price Guide

In intelligent building microgrid, a multiple input Buck-Boost DC/DC converter was adopted to replace many single input DC/DC converters, so all energy of wind-PV-water battery can be collected, the circuit structure can be simplified, the cost can be reduced, and the comprehensive utilization rate of distributed energy can be increased. By dynamic price guide, the distributed energy is prior to being used, so the load shifting can be achieved, and the total electricity fees of intelligent building microgrid can be reduced. The price difference between peak and valley of power grid can be earned by energy storing and pumped storage. Multi-distributed energy can continuously power to load individual or synchronous to increase the distributed energy absorptive capacity, which can improve the rapidity, reliability and flexibility of automatic demand response. The feasibility of multi-resource collection and stability of wind-PV-water battery hybrid power supply system can be verified by small power MATLAB simulation.
