Power system stability and security assessment is a critical field that ensures modern electrical grids operate reliably amid increasing demands, renewable integration and evolving cyber threats. This ...

Analyzing a power system's stability usually begins with a look at the open-loop Bode plot of a buck or flyback converter's power stage. From this plot, the designer extracts phase and gain data for ...

Read an introduction to this series in Part 1, and Part 2, which covers noise. This is the third and final part in a series which discusses how to properly test a power supply to ensure it will work ...

Under given scenario, accident type, and clearance time, calculate the first critical point and obtain the initial operating area. Then space division method is promoted to compress search space for ...

Negative feedback is used in voltage regulators, point-of-load (POL) regulators, voltage references, operational amplifiers (op-amps), and other electronic circuits in order to produce an accurate ...

In many power systems around the world, a major transformation is underway. Proportions of synchronous generation, generally from coal and gas-fired power plants, are rapidly reducing. At the same ...

Massive integration of inverter-based renewable energy systems has been displacing conventional generating units (mainly synchronous generators) and causing a reduction in power system inertia. This ...

In its latest monthly column for pv magazine, IEA-PVPS provides a comprehensive overview of the state-of-the-art practices, best practices, and recommendations for managing reactive power amidst the ...

In 1938 Hendrik Wade Bode, who worked at Bell Labs, published his asymptotic assessment of phase margin and gain margin, bearing his name [2]. The Bode plot is recognized for its simplicity and the ...

One concern some observers raise about the growth of inverter-based resources, such as solar, wind, and battery storage, supplying the power grid is that they don’t provide inertia. Inertia has ...

Energy markets are undergoing some massive transitions. Growing demand for electricity, when combined with the need to limit carbon emissions, drives a huge increase in renewables. This growth is ...
