The aim of this research study has been to design a gain scheduling (GS) digital controller in order to control the voltage of an islanded microgrid in the presence of fast varying loads (FVLs), and to compare it to a robust controller. The inverter which feeds the microgrid is connected to it through an inductance-capacitor-inductance (LCL) filter. The oscillatory and nonlinear behaviour of th...

Islanded microgrids have low inertia due to a large penetration of non-inertial inverter based power sources. In such systems, the primary frequency controller (PFC) faces issue higher rate change (RoCoF) and peak deviation in case sudden load or generation loss. The control becomes more challenging as variation different sources is not synchronized. This paper proposes model for dynamics an is...

Indonesia is an archipelagic country with many remote islands. Supplying electricity difficult in some islands Indonesia, such as Adaut regency of west Maluku. One solution to solve this supply problem the creation a microgrid system. However, application renewable energy on microgrids can lead several technical challenges, frequency disturbances and voltage instability. Therefore, control algo...
