Title Characteristics of Micro-grid Energy Storage technology
Abstract
In response to the sustainable development strategy of economic globalization， the micro-network technology gradually is into people's lives， as a micro-grid energy storage device an essential technology，and has been increasing attention. This paper provides an overview of energy storage technology in micro-grid， elaborated the significance of micro-grid energy storage technology research. Briefly describes several common micro-grid energy storage applications in the advantages and disadvantages of various storage methods were compared. To study the characteristics of micro-grid energy storage technologies for the purpose of simulation modeling by matlab / Simulink， the establishment of micro-optical storage network model. Including the design of PV modules， inverter control strategy， battery energy storage model structures， load switching and power establishment， the specific study of several conditions.After detailed research in photovoltaic power output fluctuations influenced by the environment， changing the micro-grid operation mode， load switching and other working conditions， the role and impact of micro-energy storage network.
Keywords Micro-grid Energy storage technology PV Battery

1．1 课题研究的背景及意义
随着全球经济的发展，化石能源消耗呈现持续上涨趋势，能源结构开始从原始化石燃料转变为清洁能源。面对日益受限的环境保护法规及日益精湛的科学技术，各国根据相应的环境、能源余量和技术突破，采用不同的能源发展方向。目前，除了已经发展成熟的以煤作为主要能源的火力发电外，各国发电机组采用多样式的能源结构。现发展趋势迅猛的有风力发电、太阳能发电等，此类新能源发电已在部分国家和地区占有市场份额[1]。针对上述现象，大力发展分布式电源，构建微网结构。
