The Application of Photovoltaic-Electric Spring Technology to Rural Power Grids

Rural power grids are essential for rural development, impacting the lives of farmers, agricultural economy, and overall efficiency production. To ensure reliable operation these grids, finding ways to provide high-quality is imperative. In recent years, penetration rate distributed photovoltaic (PV) in distribution network has been increasing. When output PV load not matched, voltage fluctuation affects safe stable network. this study, we propose that can be achieved by employing a photovoltaic-electric spring (PV-ES) device. A state space model PV-ES established single control method, based on PI controller, proposed, taking user household with monthly consumption about 120 access supply as an example. We analyzed device’s effectiveness addressing issues well how light intensity impacts its effectiveness. The implementation device solves most significant problem faced namely, unstable occurs during peak electricity periods. addition, ensures experience consumers.
