Properties of Direct-Time and Reversed-Time Transfer Functions to Locate Disturbances along Power Transmission Lines

Mario Paolone, Zhaoyang Wang, Zhe Chen

The paper discusses specific frequency-domain properties of the electromagnetic time reversal (EMTR) method applied to locate faults and, more in general, disturbances in power networks. Specifically, we investigate the properties of two transfer functions ...

Inertia location and slow network modes determine disturbance propagation in large-scale power grids

Philippe René Joseph Jacquod

Conventional generators in power grids are steadily substituted with new renewable sources of electric power. The latter are connected to the grid via inverters and as such have little, if any rotational inertia. The resulting reduction of total inertia ra ...

Quantification of Primary Frequency Control Provision from Battery Energy Storage Systems Connected to Active Distribution Networks

Mario Paolone, Fabrizio Sossan, Emil Namor, Giacomo Piero Schiapparelli

In this paper, we consider the provision of primary frequency control by using battery energy storage systems (BESSs). In particular, we use a standard droop-based frequency control for a BESS where the control action (i.e. the BESS power output) consists ...
