| Abstract: | In this paper, the problem of operating microgridswith only inverter-based energy resources is considered, and anintegrated design of grid-forming inverter control is proposed.The proposed design has three components. The first is anominal control designed to track the reference signals of voltagemagnitude and frequency. The second as the primary controlincludes the nominal control as the seed and is a Lyapunov-basedstate-constrained control designed to ensure that the frequency,voltage, and power injections dynamically satisfy the operationalconstraints while incorporating intermittent renewables. Thethird is a subgradient-based cooperative control ensuring thatthe inverters cooperatively and collectively meet the loads. Stability and convergence are analyzed to ensure robust microgridoperation in terms of various operational constraints. |
