This paper addresses the use of nanogrid technology in resolving the issue of blanket load shedding for domestic consumers. This is accomplished by using different load management techniques and load classification and utilizing maximum solar energy. The inclusion of DC-based load in basic load and DC inverter load in regular load and scheduling of the burst load during the hours of maximum solar PV generation bring novelty in this work. The term “nanogrid” as a power structure remains ambiguous in various publications so far. An effort has been done in this paper to present a concise definition of nanogrid. Demand side load management is one of the key features of nanogrid, which enables end users to know major characteristics about their energy consumption during peak and off-peak hours. A microgrid option with nanogrid facility results in a more reliable system with overall improvement in efficiency and reduction in carbon emission. PV plants produce DC power; when used directly, the loss will automatically be minimized to 16%. The AC/DC hybrid nanogrid exhibits 63% more efficiency as compared to AC-only nanogrid and nearly 18% more efficiency as compared to DC-only nanogrid. Smart load shifting smoothens the demand curve 54% more adequately than during conventional load shifting. Simulation results show that real-time pricing is more economical than flat rate tariff for a house without DG, whereas flat rate results are more economical when DG are involved in nanogrids. 12.67%-21.46% saving is achieved if only flat rates are used for DG in nanogrid instead of real-time pricing.

混合交直流纳米电网的可变负载需求方案

本文讨论了使用纳米电网技术解决国内消费者的全面减载问题。这是通过使用不同的负载管理技术和负载分类以及利用最大的太阳能来实现的。在基本负载中包含基于直流的负载，在常规负载中包含直流逆变器负载以及在最大太阳能光伏发电时间期间调度突发负载为这项工作带来了新颖性。迄今为止，“纳米网格”作为一种电源结构在各种出版物中仍然含糊不清。在本文中已努力提出纳米网格的简明定义。需求侧负载管理是纳米电网的关键特性之一，它使最终用户能够了解高峰和非高峰时段能源消耗的主要特征。带有纳米电网设施的微电网选项可产生更可靠的系统，整体提高效率并减少碳排放。光伏电站产生直流电；直接使用时，损失会自动降到16%。AC/DC 混合纳米电网的效率比纯交流纳米电网高 63%，与纯直流纳米电网相比效率高近 18%。智能负荷转移比传统负荷转移更充分地平滑需求曲线 54%。仿真结果表明，对于没有 DG 的房子，实时定价比统一费率更经济，而当 DG 参与纳米电网时，统一费率结果更经济。如果纳米电网中的 DG 仅使用统一费率而不是实时定价，则可节省 12.67%-21.46%。
