摘要

随着直流负荷的发展,直流微电网有望成为未来配电网的主流拓扑结构。为解决光伏直流微网因能量间歇性、负荷随机切换等复杂扰动造成的微网直流母线电压稳定问题,本文首先根据直流微网伏安特性建立相应的数学模型,并利用储能系统的特性制定自适应下垂控制策略,保证母线电压恒定。MATLAB / Simulink仿真算例和实验测试验证了所提方法的可行性和有效性。

Improved Droop Control of Independent Optical Storage DC Microgrid
With the development of DC load, the DC microgrid is expected to become the mainstream topology of future distribution networks. To solve the problem of DC bus voltage stability of microgrid caused by complex disturbances such as intermittent energy and random load switching of photovoltaic DC microgrid, this paper first establishes the corresponding mathematical model based on the volt-ampere characteristics of DC microgrid and uses the characteristics of energy storage system to develop an adaptive droop control strategy to ensure that the bus voltage is constant. MATLAB / Simulink simulation examples and experimental tests verify the feasibility and effectiveness of the proposed method.
