中文摘要

本文研究了有限控制集模型预测控制(FCS-MPC)算法在直流微电网中的应用,旨在解决负载点(POL)变换器在恒功率负载(CPL)特性下导致的系统不稳定问题。通过优化控制策略,有效抑制了负阻抗效应,提升了直流微电网的动态稳定性。

English Abstract

This paper investigates the possibility of deploying a finite control set model predictive control (FCS-MPC) algorithm for dynamic stabilization of a dc microgrid (MG) that supplies tightly regulated point-of-load (POL) converters. Within their control bandwidth, such converters behave as constant power loads (CPLs), where the MG sees them as impedances with a negative incremental resistance. Due ...
