Design of Flexible Interconnection Nodes in a Regional Multi-Energy Hybrid Energy Grid

With the wide application of distributed power generation and energy storage devices, the construction of energy Internet based on new energy and Internet technologies has been developing rapidly. The design of power routers connecting power grids, distributed power generation devices, energy storage devices and loads can meet the demand for energy interconnection, thus realizing the optimal scheduling and management of power consumption by loads and power generation by distributed power sources. This paper proposes the basic composition of a community energy network, with the power router as its smallest terminal to control and dispatch the home power generation system. On the basis of analyzing the design requirements of the power router, we propose a plug-and-play, multi-input and multi-output power router scheme based on solid-state transformers to realize the connection of new energy outputs, energy storage devices and loads of the home power generation system, and to carry out unified control and scheduling.
