摘要: This paper presents small-signal analysis of isolated as well interconnected autonomous hybrid distributed generation system for sudden variation in load demand, wind speed and solar radiation. The systems comprise different renewable energy resources such wind, photovoltaic (PV) fuel cell (FC) diesel engine generator (DEG) along with the storage devices flywheel (FESS) battery (BESS). Further ultracapacitors (UC) an alternative element interconnection through tie-line is incorporated into improved performance. A comparative assessment deviation frequency profile presence combinations carried out graphically terms performance index (PI), ie integral square error (ISE). Both qualitative quantitative reflects improvements profiles compared to other elements. K e y w o r d s: deviation, system, error, operation,
