Energy storage for use in load frequency control [PDF]

2010 IEEE Conference on Innovative Technologies for an Efficient and Reliable Electricity Supply, 2010
Certain energy storage technologies are well-suited to the high-frequency, high-cycling operation which is required in provision of load frequency control (LFC). To limit the total stored energy capacity required while reducing the cycling burden on traditional thermal generators, the LFC signal may be split between thermal generators and energy ...

An Adaptive Internal Model for Load Frequency Control using Extreme Learning Machine [PDF]

, 2018
As an important part of a power system, a load frequency control has to be prepared with a better controller to ensure internal frequency stability. In this paper, an Internal Model Control (IMC) scheme for a Load Frequency Control (LFC) with an adaptive
