Over the last decades, renewable energy sources have increased considerably their
generation share in power systems. As a consequence, in terms of frequency deviations …

The design of frequency regulation services plays a vital role in automation and eventually
reliable operation of power system at a satisfactory and stable level. Frequency response …

The power system inertia is gradually decreasing with the growing share of variable
renewable energy (VRE). This may jeopardize the frequency dynamics and challenges the …

The system frequency response (SFR) model describes the average network frequency
response after a disturbance and has been applied to a wide variety of dynamic studies …

Frequency drop due to loss of massive generation is a threat to power system frequency
stability. Under-frequency load shedding (UFLS) is the principal measure to prevent …

Load frequency control employs communication networks to transmit measurements and
control signals. The controller is usually designed in continuous-mode and discretized in …

This paper proposes a two-level combined control (TLCC) scheme of voltage source
converter-based multi-terminal high-voltage direct current (VSC-MTDC) integrated offshore …

The utilisation of renewable sources brings many benefits to electric power systems, but also
some challenges such as the impact that renewable power plants employing power …

Increasing photovoltaic (PV) penetration significantly diminishes system inertia that affects
systems' damping capability to regulate primary frequency control. Unlike wind turbine, PV …

Wind generation is expected to reach substantially higher levels of penetration in the near
future. With converter interface, the wind unit's rotor inertia is effectively decoupled from the …
