H∞ controller for stability enhancement in VSC HVDC system with parallel AC lines
In this paper, a state-space model for a voltage source converter based high voltage direct current (VSC HVDC) transmission link in parallel with an AC transmission line is developed using dq-coordinate system. A robust H∞ control design for the converter and inverter of the VSC HVDC system is proposed to maintain the DC voltage and control the active and reactive power at the converter stations. ...

The Benefits of Micro Inverters
The Benefits of Micro Inverters In the solar world, one of the big debates is the whole string inverter vs. micro inverter issue. Solar inverters are the devices that convert DC power being produced by the solar panel into AC power. The debate lies in which type of inverter is better, string or micro, which both have unique functions and compatibility. The Types of Inverters Inverters ...

Non-isolated single stage PFC rectifier for wide-input large step-down voltage applications
This paper proposes a non-isolated single-stage high power factor rectifier suitable for applications requiring low-voltage and high-current output. The proposed converter integrates two buck-boost converters with a buck converter. As a result, the proposed converter can operate over a wide range of input voltage with extended low output voltage capability, making it suitable for universal input ...

Offshore Wind Development Picking Up Pace
Wind power is the world’s leading source of renewable electricity, excluding hydropower, with 238,000 megawatts of capacity installed at the start of 2012. Thus far, almost all of this wind power has been tapped on land; worldwide just 4,600 megawatts of offshore wind farms were operating as of mid-2012. Offshore wind capacity is growing quickly, however, expanding nearly six-fold ...

Using Thermal Insulation in Offshore Wind Farms
Thermal insulation reduces the transfer of thermal energy between objects which have different temperatures or are within range of radiative influences. Heat flow is an inevitable outcome when objects of different temperatures interact. Thermal insulation provides a region in which thermal conduction is reduced or thermal radiation is reflected by the lower-temperature ...
