Abstract

The low-voltage DC microgrids (LVDC-MGs) have gained considerable popularity among stakeholders, researchers/engineers and have created a new trend for the development of microgrids, with the benefits of reduced conversion loss and simple control, as generation and storage technologies such as photovoltaic (PV) and battery storage have improved efficiency at a decreased cost. However, appropriate control schemes are critical for incorporating the source and load variations. The voltage stability and power-sharing between renewable energy sources (RESs) and energy storage systems (ESSs) within the microgrid are important concerns concerning stability and reliability. The performance of the proposed work is demonstrated in MATLAB Simulink for stand-alone LVDC MG with PV arrays and ESSs and analyzed under the variation of solar irradiance, which was found to be suitable for remote household electrification. The results achieved from the simulation illustrated an autonomous DCMG capable of supplying the daily energy requirements of the system with decent voltage stability.

基于太阳能光伏的自主低压直流微电网远程电气化

低压直流微电网(lvdc - mg)已经在利益相关者、研究人员/工程师中获得了相当大的普及，并创造了微电网发展的新趋势，具有减少转换损失和简单控制的好处，因为光伏(PV)和电池存储等发电和存储技术以较低的成本提高了效率。然而，适当的控制方案对于合并源和负载变化至关重要。微电网内可再生能源和储能系统之间的电压稳定和电力共享是影响微电网稳定性和可靠性的重要问题。在MATLAB Simulink中对具有光伏阵列和ESSs的独立LVDC MG进行了性能验证，并在太阳辐照度变化下进行了分析，发现该工作适用于远程家庭电气化。仿真结果表明，自主DCMG能够满足系统的日常能量需求，并具有良好的电压稳定性。
