In contrast to the previous generation of power grid codes, recent standards require that distributed energy resources (DERs) provide low-voltage ride-through (LVRT) capabilities during grid faults. Consequently, the high penetration of DERs in today's power system requires an efficient method of controlling the active and reactive power of those resources during normal as well as abnormal voltage...
Microgrids are key elements for integrating renewable resources as well as distributed energy storage systems as green sources of electricity. However, the presence of controllers is indispensable in confronting the intermittency and variable operation of renewable resources. This paper explores the control of active and reactive power flow through two modes of microgrid operations, namely islanded...
This paper presents a design of inverter controller based on the model predictive control (MPC) in the microgrid. The traditional PI controller is compared with the model predictive controller to demonstrate the advantage of MPC controller. The design concept of MPC controller is verified through several cases in this paper to demonstrate its control capability when microgrid works in grid-connected...
