Pressure Fluctuation Suppression Strategy of Underwater Compressed Air Energy Storage Airbag Based on Fuzzy PID
摘要
Abstract
Underwater compressed air energy storage(UWCAES)is vital for balancing power supply-demand fluctuations but faces challenges of instantaneous overpressure and pressure oscillations in flexible balloons during deep-sea operation and dynamic charging/discharging.This paper proposes a fuzzy PID(proportional integral derivative)-based method to suppress these pressure fluctuations.First,a dynamic pressure transmission model incorporating underwater environmental parameters is established for the balloon.Then,a fuzzy PID control algorithm is developed,utilizing the pressure error and its rate of change as inputs.This algorithm constructs membership functions and a fuzzy rule base to dynamically adjust PID parameters in real-time,optimizing the valve opening adjustment rate.Finally,case studies confirm algorithm robustness under dynamic conditions like vortex-induced shock.By achieving a 26.7%reduction in pressure standard deviation(to 30.8 kPa)over PID control,the proposed strategy effectively mitigates overpressure and fluctuations,advancing the deployment of underwater flexible compressed air energy storage.关键词
