Abstract

Abstract In the future, the electrical power supply networks will be transformed from conventional power plant structures with inertia to a complete inertia independent system. Such systems will include storages for different generation speed together with power electronic converters. In this paper, a novel method is proposed to control the electrical power distribution by these new power plants. All the control principles necessary involving spinning reserve, primary control and secondary control depending on frequency are substituted by a comprehensive angle control of the nodal voltages in the transmission and distribution network. It is observed that whenever the power requirement of the loads increase, the slack generators satisfy this rising demand with the power stations closest to the point of increasing consumption automatically producing the most power. This drastically reduces the heavy load flow and the need for general power re-dispatch measures. Reducing power re-dispatch would not only save millions of Euros on an annual basis but also lead to the formation of a more secure electrical network.
