光伏发电和液流储能电池的海水淡化系统动态特性建模与仿真
本文是针对海岛上5人团队的生活需求，把液流储能电池作太阳能光伏发电的储能系统，结合系统所处的环境，建立了一个基于光伏发电和液流储能电池的海水淡化系统。整个系统是由光伏组件、控制器、液流储能电池和逆变器以及海水淡化系统组成。光伏组件的数量根据实际用电情况而确定，液流储能电池的容量根据一天用电量以及需要电池自给的天数确定。控制器和逆变器的选择则要满足光伏组件、液流储能电池以及其负载的需求。并以一天为周期，对系统进行仿真，对比选取了最优方案，验证了设计的可行性与正确性，可以满足海岛5人的生活用电需求。

Abstract Today, the rapid development of the world economy。 Due to the uneven industrial structure, weak human consciousness to protect the Earth, the emergence of fuel energy depletion, environmental destruction and shortages of fresh water resources, serious problems on Earth。 This makes the development and utilization of new energy sources and the development of desalination technology has become a new focus。 Wherein the clean and efficient solar energy much attention。
This article is for the needs of life on the island's 5-man team, the flow energy storage batteries for solar photovoltaic energy storage system, combined with the system environment, the establishment of a desalination system based on photovoltaic and flow energy storage battery 。 The entire system is composed of photovoltaic modules, controllers, flow storage batteries and an inverter, and desalination system。 The number of PV modules based on actual power usage and determine flow battery energy storage capacity is determined based on one day of electricity consumption and the number of days required battery self-sufficiency。 Controller and inverter choice will have to meet the needs of PV modules, flow storage batteries and their load。 And there is a daily cycle, system simulation, compared to select the best program to verify the feasibility and correctness of the design to meet the island's five people living electricity demand。
