Design and Performance Investigation of Hierarchical Control Intended for Three-Phase Photovoltaic Microgrids
摘要
The present paper focuses on investigating the performance of a hierarchical control designed based on DESOGI for three-phase Photovoltaic Microgrid (PVMG) systems. The main objective of this paper is to ensure effective and optimal control of the PVMG. In this paper, a comprehensive description of the PVMG system and the corresponding control strategy are provided. The design of the primary, secondary, and tertiary controls based on MESOGI is established. In addition, the paper covers the adaptation stage, involving the DC-DC converter with a Maximum Power Point Tracker (MPPT) controller intended for the PV generator (PVG). Furthermore, it investigates the performance of the designed hierarchical control through simulation tests conducted in MATLAB. The results show how well the hierarchical control that was created was able to provide precise power sharing, adequate power flow, smooth synchronization, and proper restoration of frequency and amplitude under a variety of operating situations.
