Intelligent Control and Optimal Energy Supervision for On-Grid Hybrid Renewable Generation with Flywheel Energy Storage

Abstract

Abstract This research introduces an innovative on-grid hybrid renewable generation (OG-HRG) system characterised by its distinctive combination of three technologies: solar photovoltaic (PV), gearless permanent magnet synchronous generator (PMSG)-based wind turbines (WTs) and a flywheel energy storage system (FESS). The particularity of this system lies in its advanced incorporation of a multi-layered control approach, which merges the adaptability of fuzzy logic control (FLC), the accuracy of proportional-integral-derivative (PID) control and the resilience of sliding mode control (SMC) into a unified energy management system (EMS). This design has been specifically developed to address intermittency and maintain grid stability. Simulation outcomes validate its effectiveness, showcasing 92.3% renewable energy utilisation, minimal frequency fluctuations (±0.8%) and an 85% decrease in CO 2 emissions. This study offers a new framework for achieving high-efficiency and stable integration of renewable energy sources.
