چکیده
In this paper, a control strategy of voltage source inverter with LCL filter in distributed electrical energy systems both operation modes is proposed for microgrids environment. This robust considers state feedback controller based on proportional resonant using linear matrix inequalities. The able to ensure good tracking sinusoidal references and suppress low order harmonics. It allows simultaneously stability the system front external disturbances (grid disturbances, load variations), parametric uncertainty inductance) smooth transition (with no hazardous transients) between grid connected islanded mode operation. demonstrate efficiency performance strategy, real time simulation OP5600 from OPAL-RT used. Several case studies are verified results analyzed discussed.

Decentralized Control Strategy for Optimal Energy Management in Grid-Connected and Islanded DC Microgrids
This paper proposes a decentralized control technique to minimize the total operation cost of a DC microgrid in both grid-connected and islanded modes. In this study, a cost-based droop control scheme based on the hourly bids of all participant distributed generators (DGs) and the hourly energy price of the utility is presented. An economic power sharing technique among various types of DG unit...

متن کاملDistributed 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...
متن کاملA 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...

This paper proposes an MPC - based (model predictive control) scheme to control active and reactive powers of DERs (distributed energy resources) in a grid - connected mode (either through a bus with its associated loads as a PCC (point of common coupling) or an MG (micro - grid)). DER may be a DG (distributed generation) or an ESS (energy storage system). In the proposed scheme, the set - poin...
