Electronic control systems can provide these advantages in a cost effective solution. The application of electronic controls to a power distribution system requires a thorough development program. It is imperative to assure that the controls will provide reliable, long-term performance, as well as ...
Nanogrid is “The new ray of hope” for people living in remote isolated locations as well as where power supply reliability is poor. A nanogrid is a small power capacity distribution system with the ability to operate standalone or with a utility grid.
In the early stage, the current source converter (CSC) based HVDC system was used for the transmission of power. CSC-based HVDC systems use thyristors, and can apply to very high power rating with low losses (typically around 0.7%). However, thyristors can only be turned-on with no turn-...
The test and integration requirements for such vehicle or land systems affect several levels of the control hierarchy; from low-level power electronic converters used for propulsion and auxiliary systems to high-level supervisory controls. In this paper, we will describe a HIL test made on a ...
In recent years, wind power is experiencing a rapid growth, and large-scale wind turbines/wind farms have been developed and connected to power systems. Ho
Modern problems in control theory and their applications (singular solutions and perturbations in control systems) The controls of HVDC have an important influence on the security and stability of the power systems.As a strictly nonlinear system,HVDC needs modern contro...

In the paper, modern controls for the excitation systems for the synchronous generators are studied. The direct model reference adaptive control and the robust sliding mode control theories are analyzed and implemented for a power system stabilizers. Representative solutions are compared on the basis of...
Emerging sub-synchronous interactions (SSI) in wind-integrated power systems have added intense attention after numerous incidents in the US and China due to the involvement of series compensated transmission lines and power electronics devices. SSI phenomenon occurs when two power system elements exchang...
POWER systems are facing challenges due to the deregulation of the electricity market, environmental concerns and the impact of changing from a fossil fuel dominated system to one based on low carbon sources. The issues are further complicated by recent major blackouts, customers’ expectation of hig...
Partly because of advances in power electronic converters, the share of renewable energy in power generation is steadily increasing. The main medium of interface for integrating renewable energy sources to the utility grid is the power electronic inverte
