Operational reliability assessment considering independency between wind power ramps and frequency sensitive loads [PDF]

E3S Web of Conferences, 2021
With the increasing wind power penetration, power system frequency is more vulnerable especially when gust wind periods. Frequency control is used to restore system frequency back to the rated value.

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

Automatica, 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.

Robust and dynamic transactive energy system using Tsypkin–Polyak theorem

IET Smart Grid, 2018
In this study, a robust and dynamic transactive energy system in smart grid (SG) environment is proposed based on the Tsypkin–Polyak theorem. A key factor of the proposed system is to consider the uncertainties in electrical grid parameters.

Optimizing Method for Key Parameters of Under-frequency Load Shedding for Power System Penetrated with Hydropower

Zhongguo dianli, 2020
Under-frequency load shedding is an important part of the last defense line for power grid. However, the under-frequency load shedding device is prone to overcutting when large power shortage disturbance occurs in the grid system with high penetration of

Power-Supply Systems Reliability Control [PDF]

EAI Endorsed Transactions on Energy Web, 2018
System reliability control is proposed to maintain through the usage of the operating time between the system components' failure. Usually, trouble-free (reliability) is assessed considering component failures. Almost all the system probabilistic parameters were determined via the component failures.
