Self-Adaptive Control Strategy of Battery Energy Storage for Power Grid Primary Frequency Regulation

2022 IEEE/IAS Industrial and Commercial Power System Asia (I&CPS Asia), 2022
In order to fully play the role of battery energy storage (BES) in primary frequency regulation, this paper proposes a self-adaptive control strategy of BES for power grid primary frequency regulation. Firstly, an equivalent model of BES participation in

Research on primary frequency regulation strategy with frequency division of wind turbines

2017 IEEE Transportation Electrification Conference and Expo, Asia-Pacific (ITEC Asia-Pacific), 2017
Rotor speed changes with variation of electrical power witch controlled by converter in doubly-fed induction generator(DFIG), compared to the large thermal power unit DFIG is more suitable for adjusting the power fluctuation of fast varying component. In this paper, a primary regulating strategy of DFIG by distinguishing power fluctuating frequency is ...

Impacts of Virtual Primary Frequency Regulation on Electromechanical Oscillations

IEEE Transactions on Smart Grid, 2018
Virtual primary frequency regulation (VPFR) is a coordinated demand and generation response, which is proposed to counteract post-disturbance frequency fluctuations and deviations. But meanwhile, it also influences oscillation stability. VPFR’s continuity, slope and response time are three characteristics that have large influences on oscillation ...

Power Plant Performance Optimization Experiment on Primary Frequency Regulation

Applied Mechanics and Materials, 2013
As the increment of the power grid scale and the requirement of high power quality, the requirement of the primary frequency regulation (PFR) of large power plant i becomes more and more strictly. In order to improve the PFR performance and to ensure the safety and stability of power plant operation, an experimental analysis was carried out to optimize

Feasible Strategy for Allocating Cost of Primary Frequency Regulation

IEEE Transactions on Power Systems, 2009
Among the ancillary services, a great number of cost allocation strategies have been broadly developed in the deregulated environment. Generally, the utilization of such services can be determined by directly evaluating the actual amount of the usage or by indirectly analyzing the fair/reasonable contribution/attribution to the market participants.
