6 FAQs about [Control method of Wanshan Island microgrid]

What is a GA-Ann microgrid?

The GA-ANN is used to control the frequency of a microgrid in an island mode to automatically adjust and optimize the coefficients of a PI-controller. The proposed PI-controller is located in the frequency control secondary loop of an island microgrid.

Can a hybrid multi-source Islanded microgrid stabilize DC bus voltage?

Conclusions In this paper, a novel power balance control method for the hybrid multi-source islanded microgrid system is adopted, which can stabilize the DC bus voltage and restore the frequency and voltage amplitude and achieve active power sharing.

How does a microgrid work?

When connected to the grid, the microgrid's frequency and power are functions of the main grid and only need to be controlled for the power of the units, but on islands, the microgrid's frequency and voltage fluctuate need an independent control 3, 4.

Can a PSO-based Ann control a microgrid?

A load frequency control using a PSO-based ANN for micro-grids in the presence of electric vehicles. Int. J. Ambient Energy 42 (6), 688–700 (2021). Mahrouch, A. & Ouassaid, M. Primary frequency regulation based on deloaded control, ANN, and 3D-fuzzy logic controller for hybrid autonomous microgrid. Technol. Econ. Smart Grids Sustain.

Why should a microgrid controller be able to handle load changes?

Load changes are always noticed by the microgrids and the microgrid controller must be able to quickly dampen the frequency fluctuations caused by the imbalance of production and power consumption in the shortest possible time and with the least fluctuations.

Which controllers are used in a microgrid?

In 8, 9, controllers based on PI control and proportional-integral-derivative controller (PID) have been used. In 10 the particle swarm optimization (PSO) algorithm and in 9 the spider social behavior (SSO) algorithm is used to optimize the PID control parameters in the microgrid.
