The Role of Energy Storage in Mitigating Wind Power Intermittency

Abstract

Effective mitigation of wind power intermittency requires cutting-edge energy storage solutions since it poses great problems for grid stability and dependable electricity supply. This study examines the crucial function of energy storage systems in resolving wind power variation by thorough examination of grid integration methods, hybrid storage configurations, and battery technology. For their ability to smooth wind power variations, the research assesses Battery Energy Storage Systems (BESS), Compressed Air Energy Storage (CAES), and lithium-ion technologies. Using HOMER and MATLAB optimization techniques, including Particle Swarm Optimization and Robust Model Predictive Control, the best energy storage configurations are found for several wind farm situations. Results show that BESS performs better in voltage stabilization and frequency regulation while keeping grid stability measures within permissible levels. Economic study shows that combining lithium-ion batteries into 30 MW wind farms has a positive Net Present Value, which means they are good for business. These results show that energy storage is very important for making wind power more popular because it helps to solve the technical and economic problems that come with wind power varying. This supports the change to renewable energy, which is good for the environment.
