Research on Grid-Connected Energy Storage Technology and Engineering Applications
摘要
Abstract
high-proportion new energy power systems face challenges including inertia deficiency,wide-band oscillation,and voltage instability.To address these,the research focuses on technological breakthroughs and engineering applications of grid-connected ener-gy storage.It proposes and implements a grid-forming PV-storage coordination control algorithm,enabling PV inverters and storage converters to jointly establish grid voltage and frequency autonomously.It develops"Virtual impedance+Distributed synchronization control"technology to enhance multi-unit parallel stability,expanding the short-circuit ratio(SCR)adaptation range to 1.0.It con-structs a five-dimensional security protection system spanning cell,pack,cluster,system,and grid levels.Empirical results demon-strate that this approach increases renewable energy accommodation by 15%～20%,enhances system inertia support capability by over 5 times(inertia response time improved from 0.5 s to 3 s),achieves 85%wide-band oscillation suppression,and ensures"no fire,no propagation,no explosion"during thermal runaway.The research innovatively integrates coordinated PV-storage grid-forming con-trol,multi-unit parallel technology for extremely weak grids(SCR=1.0),and a five-level intrinsic safety architecture.It provides an effective stability solution for high-proportion new energy power systems.关键词
