DC microgrids and distribution systems: An overview

Voltage control of DC islanded microgrids: A decentralized scalable approach

“…For evaluating the PnP capabilities of our control approach, we simulate the connection of DGUΣ DGU [6] witĥ Σ DGU [1] andΣ DGU [5] , as shown in Figure 5. Therefore, we have…”

“…However, we highlight that previous controllers for DGUsΣ DGU [1] and Σ DGU [5] can be also maintained, provided that the already computed matrices K j , j ∈ N 6 still fulfill all constraints in (15) for the new ImG topology. Since this test succeeds, we proceed by executing Algorithm 1 for synthesizing C [6] for the new DGU only. Algorithm 1 never stops in Step A and therefore the addition ofΣ DGU [6] is allowed.…”

“…The real-time plugging-in ofΣ DGU [6] is executed at time t = 2 s. Until the plug-in ofΣ DGU [6] , common reference v M G for DGUs 1-5 is the same as for DGUs 1-2 in Scenario 1 and the subsystemΣ DGU [6] is assumed to work isolated, tracking the reference voltage v M G . We note that right after the hot plug-in ofΣ DGU [6] at t = 2 s, load voltages ofΣ DGU [1] and www.microgrids.et.aau.dk (in red).…”

“…PV panels), batteries and loads (e.g. electronic appliances, LEDs and electric vehicles), has triggered a major interest in DC microgrids [5], [6].…”
