What is Microgrid Hierarchical Control?
Microgrid Hierarchical Control structures primary, secondary, and tertiary control layers to manage droop-controlled AC/DC microgrids in islanded and grid-connected modes for stable power sharing and voltage regulation.
This control paradigm standardizes microgrid operations across local droop-based primary control, restorative secondary control, and optimization-focused tertiary control. Guerrero et al. (2010) proposed a general standardization framework with 4779 citations. Bidram and Davoudi (2012) detailed the hierarchical structure in 1443 cited works.
Why It Matters
Hierarchical control enables resilient microgrid operation amid renewables intermittency, supporting islanded mode transitions for remote communities and military bases. Guerrero et al. (2010) standardization facilitates plug-and-play integration of distributed generators. Shafiee et al. (2013) distributed secondary control (1041 citations) improves power sharing accuracy by 20-30% in experimental setups, reducing outage risks in urban outages.
Key Research Challenges
Plug-and-Play Integration
Ensuring seamless addition of heterogeneous distributed generators without redesigning controllers challenges scalability. Guerrero et al. (2010) highlight standardization gaps in AC/DC hybrids. Bidram et al. (2013) note feedback linearization limits under varying topologies.
Islanded Mode Stability
Maintaining frequency and voltage during grid disconnection requires robust droop restoration. Shafiee et al. (2013) address secondary control deviations in droop schemes. Dragičević et al. (2015) review DC microgrid stabilization under load steps.
Multi-Energy Coordination
Integrating electrical, thermal, and gas systems demands unified hierarchical optimization. Mancarella (2013) outlines multi-energy system models with 1324 citations. Han et al. (2016) discuss active/reactive power sharing conflicts.
