微电网系统可持续性评估与规划应用

Sustainability Assessment and Planning Application of Microgrid Systems

为了解决离网型微电网系统在负荷变化后如何判断其可持续性供电能力的问题,提出了一种微电网系统可持续性分析及其增容规划的方法。该方式按照全面的分布式电源发电量可持续性系数、储能功率可持续性系数、储能容量可持续性系数这3个指标的计算顺序,对微电网系统进行可持续性评估。此外还分别研究了分布式电源、分布式储能容量和分布式储能额定功率的优化算法,用于微电网设备的增容规划。

To address the issue of how to determine the sustainable power supply capacity of off-grid microgrid systems in response to changes in load,this paper proposes a method for sustainable analysis and capacity planning of microgrid systems.The sustainable assessment is conducted in the sequence of calculating the sustainability coefficients of distributed power generation,energy storage power,and energy storage capacity,respectively.Optimization algorithms are then studied for distributed power generation,distributed energy storage capacity,and distributed energy storage rated power,which are used for microgrid equipment capacity planning.
