Multi-variable H-infinity Robust Control Applied to Primary Frequency Regulation in Micro-grids with Large Integration of Photovoltaic Energy Source

Résumé

In this paper, different control strategies arepresented for primary frequency regulation in a dieselphotovoltaic-supercapacitor hybrid power generation system.Firstly, a classical control approach is proposed as a reference.Then, a robust control design based on H∞ control theory isapplied to the studied system. Starting from given certain desiredperformances, Linear Matrix Inequalities (LMI) are used to solvethe H∞ controller design problem. In the second step, severalmodeling uncertainties are included and m-analysis is carried outto determine the maximum variation range of each uncertaintyfor which the system is still stable and desired performances aremet. Numerical simulation results show the effectiveness of theH∞ robust control strategy when compared with the classicalcontrol strategy used for this type of hybrid power generationsystem.
