Power Quality Improvement Techniques for Renewable Energy Sources Integrated Power System

We are using solar photovoltaic systems, wind turbines and hydroelectric power plants of-ten now. This is because people want to use energy that's good for the environment and lasts a long time. There are some problems with using these kinds of energy. They do not always work because they depend on the weather. Solar photovoltaic systems and wind turbines can cause problems for the power grid. They can make the voltage go up and down. They can also make the frequency of the power unstable. Sometimes they can even make the power a little distorted. To fix these problems we need devices that can store en-ergy. We also need inverters and advanced power electronic converters. These things help the power grid work better. They make sure the electricity gets to people’s homes safely. So, to make sure that Renewable Energy Sources like solar photovoltaic systems and wind turbines work well with the power grid we have to follow the rules, for the grid closely. This is important for Renewable Energy Sources to work properly. This study presents a hybrid renewable setup combining solar and wind energy, supported by battery backup. The configuration employs MPPT controllers, voltage regulation units such as boost con-verters, inverter components, and synchronization mechanisms. Focusing on reducing harmonics, enhancing power quality, and minimizing deviations in voltage and frequency. Real-time control strategies are applied to ensure high efficiency. The study also explores how complying with grid codes can support stable renewable integration. Ultimately, the objectives are to develop a scalable and effective framework for RES integration that boosts power quality, maintains grid stability, and contributes to global clean energy goals.
