Storage-Transmission Joint Planning Method to Deal with Insufficient Flexibility and Transmission Congestion

open access: yesFrontiers in Energy Research, 2021
The insufficient power system flexibility and transmission congestion are two fundamental reasons for wind power curtailment. As the scale of the wind power in the power system is growing rapidly, the two factors of wind power curtailment events coexist ...

Risk–Based Admissibility Analysis of Wind Power Integration into Power System With Energy Storage System

open access: yesIEEE Access, 2018
The increasing high penetration of wind power will further increase the uncertainty in power systems, and three key issues should be addressed: 1) determining the maximum accommodation level of wind power without sacrificing system reliability; 2 ...

Power-Imbalance Allocation Control of Power Systems-Secondary Frequency Control [PDF]

open access: yesAutomatica, 2018
The traditional secondary frequency control of power systems restores nominal frequency by steering Area Control Errors (ACEs) to zero. Existing methods are a form of integral control with the characteristic that large control gain coefficients introduce an overshoot and small ones result in a slow convergence to a steady state.

Coherency Control in Power Systems

open access: yesCoRR
This paper proposes a coherency control strategy for Inverter-Based Resources (IBRs) to establish coherence among power system devices. Using the equivalence of the Complex Frequency (CF) of the injected currents as the definition for coherency among devices, the control enforces an output current with a proportional magnitude and a constant phase ...
