The future of the grid includes distributed generation and smart grid technologies. Demand Side Management (DSM) systems will also be essential to achieve a high level of reliability and robustness in power systems. To do that, expanding the Advanced Metering Infrastructure (AMI) and Energy Management Systems (EMS) are necessary. The trend direction is towards the creation of energy resource hubs, such as the smart community concept. This paper presents a smart multiconverter system for residential/housing sector with a Hybrid Energy Storage System (HESS) consisting of supercapacitor and battery, and with local photovoltaic (PV) energy source integration. The device works as a distributed energy unit located in each house of the community, receiving active power set-points provided by a smart community EMS. This central EMS is responsible for managing the active energy flows between the electricity grid, renewable energy sources, storage equipment and loads existing in the community. The proposed multiconverter is responsible for complying with the reference active power set-points with proper power quality; guaranteeing that the local PV modules operate with a Maximum Power Point Tracking (MPPT) algorithm; and extending the lifetime of the battery thanks to a cooperative operation of the HESS. A simulation model has been developed in order to show the detailed operation of the system. Finally, a prototype of the multiconverter platform has been implemented and some experimental tests have been carried out to validate it.
电网的未来包括分布式发电和智能电网技术。需求侧管理（DSM）系统对于实现电力系统的高可靠性和稳健性也至关重要。为此，扩展高级计量基础设施（AMI）和能源管理系统（EMS）是必要的。发展趋势是朝着创建能源资源枢纽的方向，比如智能社区概念。本文提出了一种用于住宅/住房领域的智能多变换器系统，该系统带有一个由超级电容器和电池组成的混合储能系统（HESS），并集成了本地光伏（PV）能源。该装置作为一个分布式能源单元，位于社区的每一户住宅中，接收智能社区EMS提供的有功功率设定点。这个中央EMS负责管理电网、可再生能源、储能设备和社区内现有负载之间的有功能量流。所提出的多变换器负责以适当的电能质量符合参考有功功率设定点；确保本地光伏模块采用最大功率点跟踪（MPPT）算法运行；并通过HESS的协同运行来延长电池的使用寿命。为了展示系统的详细运行情况，已经开发了一个仿真模型。最后，已经实现了多变换器平台的原型，并进行了一些实验测试来对其进行验证。
