Abstract

Photovoltaic (PV) systems are emerging as a prevalent renewable energy source for electricity generation. PV systems utilize photovoltaic cells for converting solar energy to electrical energy. However, the intermittent nature of solar energy limits the applications of PV systems in numerous fields of power engineering. To overcome this limitation, this paper presents a hardware prototype of the grid connected PV system with energy management system using batteries. The battery based energy management system provides a stable and reliable power output from PV system irrespective of the variations in solar energy. The energy management deploys bi-directional DC-DC converter for controlled charging and discharging of batteries. Single phase inverter has been employed for converting DC power output from PV cells to AC power. The grid synchronization control of the inverter has been achieved through TI-MSP430 microcontroller launch pad kit. Various modes of operation of the grid connected PV system are tested using the developed hardware prototype.

并网光伏系统与能源管理方案的硬件实现

光伏(PV)系统正在成为一种流行的可再生能源发电。光伏系统利用光伏电池将太阳能转化为电能。然而，太阳能的间歇性限制了光伏系统在许多电力工程领域的应用。为了克服这一限制，本文提出了一种具有电池能量管理系统的并网光伏系统的硬件原型。基于电池的能量管理系统提供稳定可靠的光伏系统输出功率，而不受太阳能变化的影响。能量管理采用双向DC-DC变换器，实现电池的可控充放电。单相逆变器用于将光伏电池输出的直流功率转换为交流功率。通过TI-MSP430单片机发射台套件实现了逆变器的电网同步控制。利用开发的硬件样机对并网光伏系统的各种运行模式进行了测试。
