离网型海岛综合能源微电网架构设计与实现

Architecture Design and Implementation of Off-grid Multi-energy Micro-grid in Marine Areas

传统的海岛微电网能源形式单一,考虑柔性负荷参与能量调节较少,网架结构简单。设计海岛综合能源微电网功能架构,充分利用波浪能、风能、太阳能等清洁能源,通过虚拟同步发电机技术提高分布式能源发电的稳定性,以能源路由器作为控制核心,灵活调节海水淡化装置、电转气装置等柔性负荷,实现源荷互动控制,研究能源路由器、虚拟同步发电机、源荷互动、信息物理融合系统在海岛微电网中的实现方式,并应用到车牛山岛微电网示范工程。

Traditional micro-grids in marine areas have the disadvantages of single energy, less participating in energy regulation of flexible loads, and simple grid structure. Against these disadvantages the functional architecture of multi-energy micro-grid in marine areas was designed in this paper. The micro-grid made full use of the characteristics of clean energy such as wave, wind and solar, and took advantage of VSG technology, to improve the stability of distributed energy generation. Energy router was treated as the control center of the micro-grid to realize controlling source-load interaction by adjusting flexible loads such as seawater desalination device and P2 G device. Implementations of energy router, VSG, source-load interaction, CPS in micro-grid in marine areas were studied and applied to the micro-grid demonstration project in Cheniushan island.
