Autonomous Demand Response for Primary Frequency Regulation [PDF]
, 2012 The research documented within this report examines the use of autonomous demand response to provide primary frequency response in an interconnected power grid. The work builds on previous studies in several key areas: it uses a large realistic model (i.e., the interconnection of the western United States and Canada); it establishes a set of metrics ...

Primary Frequency Regulation Using HVDC Terminals Controlling Voltage Dependent Loads [PDF]
, 2020 HVDC can provide frequency regulation during disturbances (e.g., faults) by controlling the power flow between two remote AC areas. While this action reduces the power deviation in the area affected by the disturbance, it causes a power

Study on Secondary Non-Differential Frequency Modulation Control Strategy of VSG in Islanding Mode
IEEE Access, 2023 The microgrid under VSG control is conducive to the security and stability of the microgrid system. However, it still belongs to the primary regulation of frequency, and the microgrid in islanding mode has the problem that the frequency cannot be ...

Primary frequency regulation with load-side participation: stability and optimality
CoRR, 2016 We present a method to design distributed generation and demand control schemes for primary frequency regulation in power networks that guarantee asymptotic stability and ensure fairness of allocation. We impose a passivity condition on net power supply variables and provide explicit steady state conditions on a general class of generation and demand ...
