Incorporating Demand Response in Two-Stage Frequency Emergency Control
International Journal of Electrical Power and Energy Systems, 2021 Abstract A decline in power system inertia challenges the frequency control, especially in a regional receiving-end power system. Conventionally, load shedding (LS) is the principal measure to recover the reduction in frequency. This paper proposes a two-stage frequency emergency control (EC) strategy to coordinate the LS and demand response (DR ...

Emerging Frequency Control Mechanisms in IBR Dominated Power Systems
2021 IEEE PES Innovative Smart Grid Technologies - Asia (ISGT Asia), 2021As inverter-based resource (IBR) penetration increases, system inertia levels are decreasing and the type of frequency response available is changing. This paper explores the adequacy of emerging technologies in providing post-contingency frequency control in the absence of traditional synchronous generators (SGs). The three technologies considered are

Distributional Deep Reinforcement Learning-Based Emergency Frequency Control
IEEE Transactions on Power Systems, 2022Emergency frequency control is one of the most critical approaches to maintain power system stability after major disturbances. With the increasing number of grid-connected renewable energy sources, existing model-based methods of frequency control are facing up with challenges of computational speed and scalability for large-scale systems.

2018 International Conference on Power System Technology (POWERCON), 2018
In recent years, the power grid is facing more and more frequency stability challenges. In addition to traditional hydro-electric units and thermal power units, the grid requires more kinds of resources to participate in frequency emergency control, such as wind power, high-voltage direct current (HVDC), etc.

Variable Frequency Control of Induction Motors for Emergency Demand Response
Applied Mechanics and Materials, 2015The frequency variable drivers of induction motors are typically used to control mechanical load. In the paper a frequency control method is proposed to affect regime of the grid that feeds these motors. The method provides successful self-starting or restarting after significant power disturbance of group induction motors.

Aggregation of Electric Vehicles for Emergency Frequency Control of Two-Area Interconnected Grid
2020 IEEE PES Innovative Smart Grid Technologies Europe (ISGT-Europe), 2020Frequency control has become more of a concern for the reliable operation of interconnected power systems due to the integration of low inertia renewable to the grid. Electric Vehicle (EV)s have the potential to cooperate in emergency frequency control by a nonlinear control of the power system in case of large disturbances.

Study on Frequency Emergency Coordination and Optimal Control with Multitype Measures
2019 IEEE 3rd Conference on Energy Internet and Energy System Integration (EI2), 2019System moment of inertia and frequency regulation ability is decreasing with the increasing scale of UHVDC and new energy integration in China. Therefore, the frequency stability of the system is becoming increasingly prominent. The cost of traditional security control measures such as generator tripping and load-shedding is high, the low-cost DC ...

Study on emergency control based on Regional frequency response model
2011 International Conference on Advanced Power System Automation and Protection, 2011Frequency stability refers to the ability of a power system to maintain steady frequency following a severe system upset resulting in a significant imbalance between generation and load. The rate of frequency change (df/dt) is an instantaneous indicator of power deficiency and can incipient recognition of power imbalance.
