Study on Optimal Design Method for Stand-Alone SolarBattery Hybrid Power System in a Practical Environmen
中文摘要：
偏远和无电地区远离电网，采用含光储离网型发电系统是解决当地电力缺失的重要手段。为充分利用可再生能源及解决偏远和无电区的经济性供电问题，提出了以系统负载满足率、全寿命成本为主要约束因子，从用户负荷特性、太阳能资源分析、光伏组件的实际环境发电特性、储能特性、电能匹配特性等角度研究光储离网型发电系统的优化设计方法。通过对非洲某地区的供电需求分析，光储离网型发电系统较经济地满足了当地的基本供电问题。

Abstract：
Remote areas and areas without electricity are usually unable to access the power grid. An o?-grid solar-battery system is a good way to decrease local power shortages. To make full use of renewable energy and economically provide power to remote areas and areas without electricity, some additional information regarding in?uencing variables is needed. We need to identify the expected load rate and life cycle cost, load characteristic, solar resource analysis, actual environment characteristics of photovoltaic modules, energy storage, and power matching characteristics. We used these factors to optimize the design of an o?grid solar-battery system. The results show that the optimal storage of an o?-grid solar-battery system can satisfy the local basic power supply economically in a region of Africa.
