6 FAQs about [Secondary Control of Microgrid]

Is a secondary voltage control of microgrids based on distributed cooperative control?

Abstract: This paper proposes a secondary voltage control of microgrids based on the distributed cooperative control of multi-agent systems. The proposed secondary control is fully distributed; each distributed generator only requires its own information and the information of some neighbors.

How is secondary control of electric power microgrids implemented?

The secondary control of electric power microgrids is implemented through the concept of distributed cooperative control of multi-agent systems. The Lyapunov energy-based technique is adopted to derive fully distributed voltage and frequency control protocols for each DG.

What is the primary control of a microgrid?

Once a microgrid is islanded from the main power grid, the primary control is applied to maintain the voltage and frequency stability [7 – 9]. However, the primary control can lead to voltage and frequency deviations. To restore the voltage and frequency of the DGs to their nominal value, the secondary control is applied [7, 8, 10 – 13].

Can distributed secondary control improve dc microgrid performance?

Wang P, Lu X, Yang X et al (2016) An improved distributed secondary control method for DC microgrids with enhanced dynamic current sharing performance. IEEE Trans Power Electron 31 (9):6658–6673

What is secondary voltage and frequency control of microgrids?

The secondary voltage and frequency control of microgrids are designed based on the distributed cooperative control of multi-agent systems. The microgrid is considered as a multi-agent system with DGs as its agents. DGs can communicate with each other through a communication network modelled by a digraph.

What is the control objective of a secondary controller for DC microgrids?

The control objective(9)of the secondary controller for DC microgrids, satisfyingAssumption 3, can be ensured with the proposed voltage controller(16), if and only if the matrix Γ in(27)is Schur stable, which implies all the eigenvalues of matrix Γ are within the unit circle.
