Optimizing the Integration of Photovoltaic and Wind Energy Systems for Enhanced Efficiency
Abstract: This work provides a novel approach for integrating a large-capacity doubly excited induction generator (DFIG)-based wind energy system with solarphotovoltaic (PV). The suggested plan offers a practical PV-grid integration solution by utilising DFIG’s grid and rotor side power converters to pump PV power into the grid. This eliminates the requirement for a separate converter for PV power processing. Compared to a comparable rated inverter utilised in traditional PV-grid systems, the …

Mud Acid Effect on Fines Migration Problem Using a Newly Developed Al/Zr-Based Clay Stabilizer (A): Mitigation Can Happen
Abstract: Sandstone reservoirs exhibit severe fines migration problems subsequent to conventional mud acid (HCl: HF) treatments. The acid treatment proved to be effective for a relatively short period of time, with a sudden production decline owing to either that mud acid spent rapidly in close proximity to the wellbore, causing clays to migrate into the acidized area and re-plug the formation; or that the mud acid system actually weakens the structure …
