摘要

我们的目标是在直流微电网中实现直流电压的恒定。因此，我们提出了一种控制方案，通过集成了光伏阵列模块的PEC设备和带有存储装置(电池)的双向DC-DC变换器作为类似于直流电机的惯性特性，将保持直流电压恒定所需的能量传递给DCMG，以保持交流微电网在不同运行条件下的直流母线电压恒定。在不同条件下，应用MPPT算法提取光伏阵列模块的最大功率。本文将电池作为具有双向DC-DC变换器的储能装置，可以稳定负载侧出现的不期望波动，提高整个系统的动态和暂态响应。最后应用MATLAB Simulink对整个系统进行稳态响应分析，并对所提出的控制方案进行改进。

Photovoltaic and battery storage energy system connected to ac micro-grid to maintain constant DC voltage

Our aim is to achieving maintain constant DC voltage in dc micro-grid. Therefore we proposed control scheme to maintain DC bus voltage constant in AC micro-grid under different operating condition via the help of PEC equipment integrated with PV array module and bi-directional DC-DC convertor with storage device (batteries) which behave as similar inertia characteristics DC machine they delivered to the required amount of energy to DCMG for maintaining constant dc voltage and maintain the stability. We also extract the maximum power from PV array module via application of MPPT algorithm under different condition. In this paper battery considered as storage device with bi-directional DC-DC convertor which can stable the unwanted fluctuation occurred on load side and improve dynamic & transient response of the whole system. And finally response analysis of whole system steady state analysis via application MATLAB Simulink and improve the result with proposed control scheme.
