Smart Induction Motor Variable Frequency Drives for Primary Frequency Regulation
IEEE Transactions on Energy Conversion, 2020This article proposes an induction motor variable frequency drive to investigate its potential in handling smart grid's frequency. This can thus mitigate the grid reliance on expensive power plants. To this end, a primary frequency controller is presented enabling the drive to reduce its power in proportion to grid frequency drop.

Impacts of Virtual Primary Frequency Regulation on Electromechanical Oscillations
IEEE Transactions on Smart Grid, 2018Virtual 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 ...

Application of electric vehicles for primary frequency regulation service
2021 IEEE PES Innovative Smart Grid Technologies Conference - Latin America (ISGT Latin America), 2021In the electricity system, the frequency behavior is an indicator of the quality of the service provider that expresses the equilibrium between the supply and demand of electricity. Demand presents challenging to predict behavior, which means that usually, the balance is corrected through changes in a generation. The operators rely on generation plants

Performance assessment of primary frequency regulation based on static characteristics
2019 58th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2019Regulation deadband and speed governor droop are two important performance indicators in the primary frequency regulation of thermal power unit. Coal quality, operation mode, and non-linearity of a regulating valve may cause the deviation between the frequency modulation performance index and the set value.
