“…For brevity, we will refer to the base case from [21] as Scenario A, the case with ten energy cells under the same control scheme as Scenario B, and the case with independent control of three inverters as Scenario C. Scenarios B and C each test a single variation on Scenario A for rigor's sake. Results for Scenario A can be found in [21]. While ten energy cells participate in generation in Scenario B, we have omitted the data from the additional energy cells for visual clarity; however, their effect can still be seen in the reduced power output in comparison with results from Scenarios A and C.…”

“…In [21], a real-time simulation testbed was developed to address these issues, and preliminary results from testing an augmented version of the hierarchical control strategy described in [16] were presented. The testbed features a real-time simulation with a network model and 'energy cells' (defined as the combination of photovoltaic (PV) generation, a smart inverter, and an ESS), Modbus communication capability for remote control, and the necessary hardware and simulation architecture for CHIL support.…”

“…In the initial implementation in [21], the reference values in (7)-(9) were generated based on measurements at a single, arbitrary inverter bus, and relayed to all primary controllers. This strategy is simple and effective but does lead to some inaccuracy in reference tracking.…”

The continued rise of renewable power generation requires the invention of smart grid technologies, among which communication and remote control are key. Multilevel control strategies improve grid stability and provide the necessary flexibility to address changing demand, contingency, and renewable generation variability. To test these strategies while avoiding damage to existing infrastructure or lab equipment, simulation is employed to facilitate large-scale control and protection applications. In this work, a hierarchical control strategy is tested in a real-time simulation environment implementing a moderately large microgrid with 100% renewable generation penetration, using both physical and software-based controllers, in both local-and remote-control configurations. Additionally, an adaptation is made to the existing hierarchical control strategy to accommodate energy storage balancing amongst distributed resources. The scalability of the testbed and adaptability of the control strategy are tested, and stable operation is observed.
