Super Twisting Sliding Mode Controllers based Grid Connected Hybrid Renewable Energy Sources Operated Power Supply System

Grid integrated renewable energy sources, particularly hybrid systems that combine Photovoltaic (PV) and Wind power conversion, are currently in operation in numerous locations around the globe. These systems are required novel control methods to supply quality power at local loads under different situations. These controllers help the grid to be free from unbalance and nonlinear load effects. The availability of the grid over an extended period cannot be assured; therefore, it is necessary to adopt a battery bank into the hybrid system. This integration will help maintain power balance and ensure an uninterrupted power supply to the loads. In general, operated electric loads as well as power production from wind and PV are always fluctuating and unpredictable. Hence, super twisting sliding mode controllers are adopted in the proposed methodology to make system faster and precious response. To enhance the stability of the proposed system, a new coordination strategy involving PV systems, wind energy, batteries, and the grid has been developed. The suggested control mechanism can assist in stabilizing voltage at the load point, mitigating reactive power, addressing unbalanced voltages, and nullifying imposing of harmonics into grid. The development of OPAL-RT supported Hardware-in the-Loop is incorporates a range of outcomes that exhibit realistic characteristics. Comprehensive findings are analyzed through multiple case studies to improve the importance of the developed strategy in this paper.
