Gas Turbines Power Regulation Subject to Actuator Constraints, Disturbances and Measurement Noises

An accurate understanding of the output power functionality in gas turbines concerning the fuel, inlet valve status and other parameters can provide a general overview of the turbine's performance. In this study, the problem of practical power regulation in gas turbines is investigated in the simultaneous presence of actuator constraints,...

A new generation flood defences: Dam with tidal power station including pumping capacity: A feasibility and optimisation study

A dam including a tidal power station with pumping capacity is a new type of flood defence. The negative ecological impact normally associated with closure dams is partially mitigated by including a tidal power station in the structure. Water can move through the tidal power station resulting in a reduced tidal stroke at the created lake. This...

Tidal Bridge Dynamics: Optimising the dynamic response due to wind, waves and current

Currently, there is no infrastructure between the two Indonesian islands Flores and Adonara. The islands are separated by the Larantuka Strait, which has a width varying between 600 and 1000 meters. The local government would like a bridge between the two islands. However, as the water in the 18 meter deep strait is heavily subjected to tidal...

The consideration of constrained flow solutions for the purpose of implementing a tidal power plant in the Brouwersdam reconnecting Lake Grevelingen and the North Sea

After the construction of the Grevelingendam (1965) and Brouwersdam (1971), the tidal movement in Lake Grevelingen disappeared. This caused a deterioration of ecological parameters influencing the surrounding flora and fauna and consequently a decline of the water quality set in. Amongst others, Rijkswaterstaat and the provinces of Zeeland and...

DC microgrid islands on ships

Since shipboard power systems are inherently islanded and consist of energy intensive sources and loads, it is an interesting application for dc microgrids. The object of this paper is to explore the merits of dc based shipboard power distribution as compared to conventional ac solutions. A survey of current initiatives, emerging concepts and...

Hydrodynamics of horizontal-axis tidal current turbines; A modelling approach based on Delft3D

A Horizontal-axis tidal current turbine (HATT) is a device that converts tidal energy into electrical power. The HATT uses the tidal current to generate electricity. There are plans to implement HATTs on a commercial scale in tidal farms similar to wind-turbine farms. However, experience with prototype farm arrangements in the field is lacking....
