A Solar-Photovoltaic Grid Interface Systemusing Smc Based On Lyapunov Function
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 3
Abstract
A sliding mode control technique (SMC) is used for achieving maximum power point tracking (MPPT) control of solar-PV array. The Lyapunov function-based control technique is designed and developed for the DC-AC inverter to the functions of an active power injection to the grid, balanced grid currents at unity power factor and load currents harmonics compensation.The proposed Maximum Power Point Tracking controller generates current reference directly from the sensorboard, and the current controller uses the sliding mode technique for the tight regulation of theinjected grid current.The sliding mode controller has been designed using a time-varying slidingsurface to control the sinusoidal current injected to the grid. The structure of a proposed system issimple and robust against modelling uncertainties and parameter variations.The mathematicalmodelling is developed and reliable simulations of the proposed controller are presented. The performance of solar-PV power generating system with proposed control algorithms is demonstrated using simulation and experimental studies under various operating conditions.
