基于小世界网络模型的光伏微网系统同步方法研究∗

摘要

建立了光伏微网逆变器严格的分段线性状态方程，分析其非线性动力学行为，然后以光伏微网逆变器为网络节点，研究基于小世界网络模型的光伏微网系统同步方法，并与基于邻近耦合规则的光伏微网同步进行比较。研究发现，基于小世界网络模型的光伏微网系统比传统的基于邻近耦合规则的光伏微网系统具有更短的同步时间，在外加扰动的情况下也具有更快的恢复时间。%Based on the solution to the strictly piecewise linear state equation of a photovoltaic (PV) supplied micro-grid inverter, the nonlinear dynamic behavior of PV supplied micro-grid inverter is analyzed in this paper, and each PV supplied micro-grid inverter is considered as a network node, then a synchronous method for PV supplied micro-grid is studied using the small-world network model. Studies have found that, compared with the nearest-neighbor coupling network model, the PV supplied micro-grid based on the small-world network model has a faster synchronization time, and also has a faster recovery time in case of plus disturbance.
