Understanding and quantifying the inertia of power systems with the integration of converter-
interfaced generation (CIG) plays an essential role in the safe transition to a future low …

With the increasingly serious climate change and energy crisis, photovoltaic (PV)
generation, as one of the most important renewable energy resources, has experienced …

Phasor measurement units (PMUs) are rapidly being deployed in electric power networks
across the globe. Wide-area measurement system (WAMS), which builds upon PMUs and …

To achieve clean energy targets, more renewable generators–mainly wind and photovoltaic
(PV)–are being integrated into electricity networks. However, wind and PV are non …

An online estimation method for the power system inertia constant under normal operating
conditions is proposed. First of all, a dynamic model relating the active power to the bus …

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

The system inertia is the inherent ability of the online synchronous machines to oppose
sudden changes in generation or load. With increasing share of non-synchronous …

The first part of this two-part paper proposes a technique that consists in the measurement,
through phasor measurement units, of bus frequency variations to estimate the rate of …

Accurate estimation of inertia and primary frequency regulation (PFR) capability is important
to ensure frequency stability in low-inertia power systems. This paper investigates how the …

Frequency security is an essential issue in power system operation and planning, especially
with the increasing penetration level of intermittent and non-synchronous energy sources …
