Title: Control of a PV-Wind Based DC Microgrid with Hybrid Energy Storage System Using Lyapunov Approach and Sliding Mode Control.

Abstract :

Distributed energy sources play an immense role in the present energy world in providing electrification in remote areas. Among the various distributed energy sources, a hybrid combination of solar and wind has been extensively used because of its complementary nature. The intermittent and stochastic nature of these renewables makes the storage system compulsory for providing reliable power to the load. A combination of battery and supercapacitor as hybrid storage makes a good choice due to the high energy density of batteries and the high-power density of supercapacitors. In this work, an enhanced exponential reaching law based sliding mode control is applied in the optimum torque control MPPT algorithm, for extraction of maximum power in the wind energy system. A control method based on the Lyapunov function, ensuring global asymptotic stability is implemented for the bidirectional converter of battery and supercapacitor. The implemented control scheme maintains the DC link voltage constant during solar, wind and load variations. A detailed analysis and the efficacy of the control algorithms by simulation and experimental studies is presented in this seminar.
