Control Strategy of a Rotating Power Flow Controller Based on an Improved Hybrid Particle Swarm Optimization Algorithm

open access: yesMathematical and Computational Applications
As the proportion of renewable energy sources integrated into the power grid increases, it imposes significant volatility on the grid, leading to uneven load distribution across certain transmission lines. Rotating Power Flow Controllers (RPFCs) based on

Minimisation of active power losses and number of control adjustments in the optimal reactive dispatch problem [PDF]

open access: yesIET Generation, Transmission & Distribution, 2018
Trade‐offs between power system's optimal operational performance and the minimal number of control adjustments necessary to attain a desired operating point make optimal reactive dispatch (ORD) solutions practical to system operators. In this study, a multi‐objective ORD model that provides, in terms of weighting factors, trade‐offs between minimal ...

Small-Signal Stability Analysis of the Power System Based on Active Support of Renewable Energy VSCs

open access: yesFrontiers in Energy Research, 2022
With the large-scale renewable energy access to the power system, the voltage source converters (VSCs) in the system are gradually increasing. The system inertia is weakened, which leads to the decrease in frequency supportability and affects the ...
