PASSIVITY-BASED CONTROL SYSTEM FOR STAND-ALONE HYBRID ELECTROGENERATING COMPLEX

The desire for energy independence presupposes the use of various types elements generation from renewable sources, stand-alone operation which storage devices are required. A power complex created in this way must perform a number tasks that formed by management system. control system performs these and ensures proper static dynamic characteristics with many inputs outputs. results recent world researches, as well authors experience work, show that, creating such systems, it is advisable to Passive Based Control (PBC), presenting object Port-Controlled Hamiltonian (PCH) Thanks developed method additional interconnections damping injection (Interconnection & Damping Assignment - IDA) passive provides ample opportunities adjust effects, while ensuring asymptotic stability whole. This particularly useful considered paper includes both hybrid plant electricity sun wind unit consisting battery supercapacitor module. article shows procedure PBC synthesis, according three structures influence formers (CIF) were designed investigated. These have different combinations damping, allows forming desired flows inside closed-loop therefore provide results. Among them, there maintaining voltages on DC bus module at reference levels, smoothness current transients. comparative simulation studies performed computer model synthesized was MATLAB/Simulink environment. It showed efficiency their work advantages CIF structures.
