Consensus active power sharing for islanded microgrids based on distributed angle droop control

نویسندگان

چکیده

The implementation of synchronous phasor measurement units (PMUs) in distribution networks provide accurate and GPS-based data which support the grid flexible reconfiguration, such as island partition reconnection. Utilizing high resolution PMU data, phase angle droop control can be implemented on islanded microgrids (MGs) without causing deviation frequency brought from traditional control, consequently seamless transition. In this paper, a method considering incremental cost distributed generation (DG) is proposed utilizing finite-time protocol to realize minimization consensus active power sharing DG units. addition, an observer-based voltage controller with convergence velocity meet target units’ recovery accuracy reactive sharing. through sparse communication topology exchange information their own neighbours only. effectiveness, robustness scalability are verified case studies.

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...

Synchronization and power sharing for droop-controlled inverters in islanded microgrids

Motivated by the recent and growing interest in smart grid technology, we study the operation of DC/AC inverters in an inductive microgrid. We show that a network of loads and DC/AC inverters equipped with power-frequency droop controllers can be cast as a Kuramoto model of phase-coupled oscillators. This novel description, together with results from the theory of coupled oscillators, allows us...

An Enhanced Droop Control Scheme for Islanded Microgrids

Due to the line impedance impact on islanded low-voltage microgrids, traditional droop control cannot guarantee the proper power sharing between distributed generation (DG) units. In the meanwhile, droop control would cause voltage and frequency deviation, which will influence the power quality of customers. This paper proposed an enhanced droop control scheme with autonomous frequency restorat...

Optimal Droop Control for Voltage Source Converters in Islanded Microgrids

A new procedure for the design of the droop control for voltage source converters (VSC) in islanded microgrid is presented. The droop control is commonly used to achieve the power balance in power system. It consists in a simple proportional control and the selection of its gains are commonly based only on power balance criteria. However, some values of the gains may cause poor damped responses...

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...
