Dynamic stability study of an isolated wind-diesel hybrid power system with wind power generation using IG, PMIG and PMSG: A comparison

摘要: Abstract This paper presents a comparative study of reactive power control for isolated wind-diesel hybrid system in three different cases with wind generation by induction generator (IG), permanent-magnet (PMIG) and synchronous generator. The (SG) is used diesel engine set. A mathematical model the based on small signal analysis, developed considering flow balance equations. variable needed provided static compensator (STATCOM) when done IG PMIG. When (PMSG) generation, demand fulfilled voltage source converter (VSC) which load side. new approximation VSC connected PMSG proposed such that fulfills increased requirement also increases its active equal to input power. Proportional integral (PI) gains STATCOM controllers are optimized using square error criterion (ISE). dynamic responses (1%) step increase without 1% shown. shows random change plus MATLAB/SIMULINK environment simulation.
