Review on Stability and Power Quality Problem and Mitigation on Renewable Energy Penetration in Grid System

Abstract

Abstract: An increase in the production and integration of renewable energy sources to the power grid system have begun to have an impact on the stability and security of the power grid. As renewable energy sources (RESs) like solar PV array plant and wind plant begin to displace traditional power plants, grid integration requirements have become an important issue. To ensure grid stability, additional criteria and technological constraints have been implemented. An updated assessment of current integration criteria and compliance control techniques for renewable power plant integration into the electric grid is being conducted as part of this study to close the knowledge gap. There is a comparison of the most important criterion for grid stability, including frequency stability and voltage stability, quality of power, voltage ride-through (VRT), reactive and active power controls. To meet these standards, a variety of control techniques have recently been proposed. As a result, cutting-edge options for compliance technologies and control techniques are analysed and evaluated in this paper. Additionally, a thorough examination of the benefits, challenges, and drawbacks of global harmonisation of integration requirements is included. Even though current incorporation necessities may enhance grid security, stability, operation, and dependability, a thorough assessment concludes that further improvements to shielding legislation, optimization of control system and international harmonisation are still required. There are a number of recommendations for further research into the integration and technical limitations of RESs that follow this. This study's findings could help to create a seamless and stable grid integration of RESs, as well as aid researchers in the development of new design methods and control systems based on current requirements. Educate and support operators in power system for creating or cultivating their individual standards that differ from the international norms that remain in place.
