Ultimate Boundedness of Voltage Droop Control With Distributed Secondary Control Loops
IEEE Transactions on Smart Grid, 2019Conditions are derived for ultimate boundedness of voltage stabilization and reactive power balancing in electrical microgrids with voltage (E-Q) droop control and distributed secondary control loops. This paper shows that under a bound on the load reactive power demand, an ultimate bound set and its associated region of attraction can be computed for ...

Distributed Estimation and Secondary Control of Autonomous Microgrid
IEEE Transactions on Power Systems, 2016This paper proposes a systematic approach to balance the active power between photovoltaic generators (PVs) and loads in autonomous microgrids. To achieve this, a distributed algorithm is designed to estimate the power difference between generation and consumption, then a finite-time consensus protocol is introduced to regulate the outputs of all the ...

Economic Dispatch by Secondary Distributed Control in Microgrids
2019 21st European Conference on Power Electronics and Applications (EPE '19 ECCE Europe), 2019This paper proposes a distributed controller in order to achieve the economic dispatch (ED) of a microgrid, which complies with the Karush-Kuhn-Tucker optimality conditions for a linear optimal power flow formulation. The consensus over the Lagrange multipliers allows an optimal dispatch without considering an electrical microgrid model, preserving the

Distributed power control for secondary spectrum trading with incumbent protection
2013 IEEE 24th International Symposium on Personal, Indoor and Mobile Radio Communications (PIMRC Workshops), 2013Spectrum trading allows incumbents of spectrum to increase their profit margins by selling portions of unused spectrum to secondary systems. While being a spectrally efficient process; interference from secondary usage degrades the performance of the incumbent network.

A Distributed Secondary-Tertiary Coordinated Control Framework for Islanded Microgrids
2020 IEEE 18th International Conference on Industrial Informatics (INDIN), 2020In this paper, a fully distributed secondary-tertiary coordinated control framework for islanded ac microgrids has been proposed. First, the distributed secondary control for frequency restoration, voltage regulation and power sharing has been proposed. Therefore, the system frequency and bus voltages can be maintained at set points. Each DG can follow

Distributed Discrete Robust Secondary Cooperative Control for Islanded Microgrids
IEEE Transactions on Smart Grid, 2019It is desirable to develop robust controllers for fast frequency/voltage regulation and active/reactive power sharing in an islanded microgrid with high penetration level of renewable energy sources. This paper proposes a fully distributed discrete two-level control strategy for islanded microgrids.

Distributed Cooperative Secondary Control of Microgrids with Bounded Control Input
2016This paper proposes a distributed cooperative secondary control of microgrids (MG) operated in islanded mode with bounded control input. Although the primary control can maintain the voltage and frequency stable when the microgrid switches to islanded mode, it leads to the voltage and frequency of each DG deviations. The secondary control is applied to

Distributed Secondary Frequency Control Algorithm Considering Storage Efficiency
IEEE Transactions on Smart Grid, 2018Storage technologies, such as batteries, have higher ramping capability than conventional generators, and so they could lead to better dynamic tracking performance when following a frequency control signal. However, storage units are energy constrained, so the energy content of the signal they follow should preferably be low.

Nonlinear consensus for improved resilience of distributed secondary frequency control
2019 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2019The integration of renewable energy sources into electrical power systems requires an increasing degree of automation in grid control and thereby leads to a higher vulnerability with respect to cyber-attacks. The response to this challenge should be twofold: first, it should be made as difficult as possible to perform successful cyber-attacks through ...
