This paper takes a large photovoltaic plant as a pilot platform to research the micro gird. In the micro grid, DC bus is the key structure, photovoltaic panels are the micro power source, lithium iron phosphate batteries are the energy storage device, and four converters are used as energy conversion device. This paper studies its specific characters such as component unit, control strategy, monitoring system and investment model. the paper builds a valuation model in the investing of energy micro system by using discounted cash flow model. According to power cost model, ecological and economic benefits are analysed and summarized, providing reference for the further application of construction on photovoltaic micro grid projects.
