Abstract
In islanded microgrids (MGs), voltage source inverters (VSIs) can be coupled in parallel to share active power while keeping the frequency at a nominal value. To this end, a hierarchical control framework includes a primary level, commonly based on the droop method, and a secondary level in which several integral policies stand out, among them is the 'distributed-averaging' approach. The latter is a policy inspired by cooperative control techniques that has been applied with satisfactory results...
