ECOGRID: LOAD-SIDE CONVERTER-ENHANCED PV-WIND HYBRID SYSTEMS FOR MAXIMUM EFFICIENCY

Abstract

The integration of renewable energy sources such as photovoltaic (PV) and wind generators into the electrical grid has become critical for sustainable energy development. However, variability in generation and inefficient power conversion can reduce grid reliability and overall system efficiency. This study presents EcoGrid, an integrated PVwind hybrid system design enhanced with load-side converters to maximize energy utilization and grid efficiency. By employing advanced simulation techniques, the system coordinates power flow between PV and wind generators, regulates voltage and frequency, and optimizes energy transfer to the grid under dynamic load conditions. Results from simulation demonstrate improved power quality, higher energy efficiency, and reduced losses compared to conventional hybrid configurations. The study highlights the potential of coordinated converter-based hybrid systems to support stable, efficient, and reliable integration of renewable energy into modern electrical grids.
