Renewable energy is the alternative sources of electrical energy to fulfill energy shortage. micro grid allows to connect multiple renewable energy sources to it. Photovoltaic (PV) generation is one of the major renewable energy sources. PV generation systems directly connected to micro grid brings some problems like voltage deviation, current fluctuation etc. which brings instability into the system. Thus, a smooth micro grid connection with PV system is required. Here H∞ control method based on model matching technique has been adopted for our system. To extract maximum power from PV array, P and O MPPT algorithm has been adopted.
Mathematical modellings for the design of H∞ Controller has been done here.Using Robust control tool box gain of the controller are found, all the eigen values of H∞ control system have negative real part, Hence voltage tracking control system is stable.
