摘要: An AC microgrid (MG) system links the distributed generation (DG) based on renewable energy resources and local electrical loads in modern power systems. Intermittent characteristics of wind solar influence not only availability but also stability entire microgrid. This matter as well makes a challenge load frequency control (LFC) problem an islanded MG system, consequently, fixed structure controllers are unable to provide proper performance over wide range operating conditions. Therefore, it is required design dedicated controller for LFC ensure capability maintaining generation–load balance by managing intermittent resources. In this paper, adaptive type-2 fuzzy PID (T2FPID) suggested enforce deviation zero supplying demands. The designed T2FPID nonlinear that can handle nonlinearities uncertainties better way. Using Lyapunov function, evaluated parameter tuning laws derived using function. It has been illustrated parameters bounded reaches properly. proposed applied simulation results have compared with those obtained type-1 (T1F) PI nonadaptive controllers, which latest research hand. indicate efficiency dealing changing parameters.
