Distributed Control Method for Economic Dispatch in Islanded Microgrids With Renewable Energy Sources

Distributed Nonlinear Robust Control for Power Flow in Islanded Microgrids

In this paper, a robust local controller has been designed to balance the power for distributed energy resources (DERs) in an islanded microgrid. Three different DER types are considered in this study; photovoltaic systems, battery energy storage systems, and synchronous generators. Since DER dynamics are nonlinear and uncertain, which may destabilize the power system or decrease the performanc...

A Robust Control Strategy for Distributed Generations in Islanded Microgrids

This paper presents a robust control scheme for distributed generations (DGs) in islanded mode operation of a microgrid (MG). In this strategy, assuming a dynamic slack bus with constant voltage magnitude and phase angle, nonlinear equations of the MG are solved in the slack-voltage-oriented synchronous reference frame, and the instantaneous active and reactive power reference for the slack bus...

Islanded Operation of Microgrids with Inverter Connected Renewable Energy Resources

This paper contains a control scheme for power sharing in islanded microgrids with invertersourced distributed energy resources that combines robust control and droop control. As the load within the microgrid changes, the inverter-sourced generators share the change in the load; this paper shows that the uncontrolled load sharing among the generators will be arbitrary and methods such as droop ...

A Novel Distributed Control Method for Economic Dispatch in Islanded Microgrid

A Local Power Control Scheme for Electronically Interfaced Distributed Generators in Islanded Microgrids

The conventional real power-frequency and reactive power-voltage droop characteristics are commonly employed to share the electric power among parallel distributed generation (DG) units. Despite some advantages such as easy implementation and no need for communication infrastructure, inaccurate reactive power sharing is one of the main disadvantages of conventional droop control. This paper pre...
