Abstract
This paper proposes an Optimal Power Flow for defining the minimum load to be shed to maintain the steady-state frequency between allowable limits in islanded microgrids. The droop coefficients and setpoints (no-load voltage and frequency of each Distributed Generator) are optimized considering the limits of microgrid frequency, nodal voltages, and power generation (apparent and reactive powers). The approach is applied to a microgrid of 33 nodes, considering a 24 hours time-horizon. The found results point to the methodology effectiveness.
