New Distributed Optimization Method for TSO–DSO Coordinated Grid Operation Preserving Power System Operator Sovereignty

Electrical power system operators (SOs) are free to realize grid operations according their own strategies. However, because resulting flows also depend on the actions of neighboring SOs, appropriate coordination is needed improve states from an overall perspective and individual SO perspective. In this paper, a new method presented that preserves data integrity SOs independent operation grids. This compared with non-coordinated local control another sequential has been identified as most promising distributed optimization in previous research. The time series simulations use transformer tap positioning well generation unit voltage setpoints reactive injections flexibilities. methods tested multi-voltage, multi-SO, realistic benchmark different objective combinations SOs. conclusion, results much closer theoretical optimum represented by central than those other two methods. Furthermore, introduced integrates sophisticated procedure provide fairness between missing
