An efficient DC grid based PV — wind power generation using modified PO tracking technique

摘要

This paper focuses on efficient hybrid microgrid which consists of wind and solar power generating sources with an efficient and reliable grid connection. The proposed system will execute modified Perturb and observe maximum power point tracking technique for both wind and solar generating unit to maximize the simultaneous extraction of energy from the entire power generation unit under different weather and load conditions. This system eliminates the need to synchronize the system frequency, phase and voltage, which allows flexible operation of multiple parallel connected wind and solar generators at the grid. The simulation output of proposed system will be demonstrated under different weather and load conditions.
