Electrical power-grid system stability is essential to provide robust power to allconsumers. The models for electrical-power transmission for synchronous generatorsprovide an exact description of power flow and stability requirements for moretraditional power grids with mechanical generators. Higher-order models can describe thevoltage and rotor-angle with great accuracy, but can only be tackled computationally dueto the dimensionality of the equations and the size of the network. Two main aspects ofemploying there models are the sheer dependency of reductions, as the assumption oflossless lines of the power grid, and the physical existence of generators with inertia. Wehave obtained strict mathematical criteria for the stability of the dynamics of the powergrid in both synchronous machines and inverter-based models, without any assumptionson line losses or the topological structure of the network. These criteria entail a greaterdetail on the fundamental criteria required to safely operate power grids, in particular notdiscarding the influence of dissipative effects, as well as providing a direct correlation ofsystems composed of inverter power systems as well as mechanical generators. Theseresults are particularly important for the ongoing transitions into a more renewable-basedpower system, incorporating a growing number of zero-inertial generators in the powergrid. |
