An automatic power allocation method of photovoltaic/electricity complementary power supply system

为了最大限度地提升光电互补供电系统的投入产出比,文章在给出了一种光电互补供电系统结构的基础上,提出了一套功率自动分配方法。为了描述光伏电池的供电能力,建立了供电能力矩阵;根据不同负载的用电情况,建立了优先级矩阵;在考虑市电峰谷电价的基础上,实现了功率分配的快速、自动、准确控制。实例分析表明该功率自动分配方法能大大提升光电互补系统的经济效益。

In order to maximize the ratio of the input and output about photovoltaic complementary power supply system, a set of automatic allocation methods for power optimization is proposed based on the structure of a kind of photoelectric complementary power supply system. In order to describe the power supply capacity of photovoltaic cells, the power supply capacity matrix is presented. A pri- ority matrix is established for the use of different loads. Considering the peak and valley price, a set of power optimization allocation algorithms is proposed which can achieve the fast, automatic and accurate control of the system. An example is given to verify that the proposed method can greatly improve the economic benefits of the photovoltaic complementary system.
