Hierarchical Control System for PV Microgrid Applications

Abstract:

DC microgrid can effectively play to the value and benefits of the distributed power supply, communication than micro grid-connected have the ability to stronger more flexible refactoring and therefore become a new trend micro grid-connected technology research. Based on photovoltaic DC microgrid as example, this paper aimed at the DC microgrid voltage stability problem, proposes a layered coordination control DC bus voltage, the method is based on the detection and control of DC bus voltage variation to coordinate photovoltaic battery energy storage interface, net side interface and the interface converter works, ensure that under different conditions can keep the grid-connected in active power balance. Using Matlab/Simulink simulation and experimental verification, the results verified the effectiveness and feasibility of the method.
