Due to increasing amounts of energy being supplied by intermittent renewable energy
sources, future energy systems need to be able to react flexibly to sudden changes. To …

The continuous-time model is widely used to design load frequency control (LFC) schemes
for power systems with delays and demand response (DR). In practice, however, the LFC …

This paper presents a new methodology to exploit consumers' flexibility for the provision of
ancillary services (AS) in the smart grid era. The proposed framework offers a control-based …

To enhance the quality of output power from regional interconnected power grid and
strengthen the stability of overall system, a hybrid energy storage system (HESS) is applied …

Due to an increase in intermittent renewable energy penetration, the mechanical inertia of
power systems has gradually decreased, threatening system frequency stability. As one …

In load frequency control (LFC) study of a large power system, the key concept is control
area, which is the segment of the system consisting of strongly interconnected buses …

Effective frequency regulation can be severely hampered due to nonlinear components and
channel delay in control loops of interconnected power systems. Currently employed …

Due to the increase of power transmission capacity, once an active power vacancy happens,
power systems will face a serious frequency instability problem. With the development of …

Recently, demand-side resources (DSRs) have proceeded to participate in frequency
control of the power systems. Compared with traditional generation-side resources, DSRs …

with a variety of new energy access to the power grid, its frequency control is facing many
new challenges, and the demand response resources play an increasingly important role in …
