Variable susceptance excitation control for dynamic performance improvement of a stand-alone wind turbine induction generator system
Isolated wind farms employ simple squirrel cage induction generators driven by variable speed wind turbines. Lacking control capability, such generation can contribute very little to network support. Wind turbines mostly do not take part in voltage and frequency control and if a disturbance occurs, the turbines may be disconnected and reconnected when normal operation has been resumed. From ...

A combined electro-mechanical control technique for dynamic voltage regulation of a stand-alone wind turbine generator
This paper introduces a computer-based model and dynamic simulation of a combined electro-mechanical control technique for a stand-alone wind turbine generator system. The presented combined control technique consists of three closed loops for speed regulation, nacelle alignment and dynamic load voltage regulation. Speed regulation is achieved by adjusting the pitch angle of the turbine blades. ...

Managing Battery Charging - Using Diversion Loads
Tcharge regulation can be relatively simple: When the I-'1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. Often, diversion control is the solution. Off-grid "hybrid" combinations of solar, wind, or microhydro have been around for decades. These renewable ...

Wind Tops 10 Percent Share of Electricity in Five U.S. States
A new picture is emerging in the U.S. power sector. In 2007, electricity generation from coal peaked, dropping by close to 4 percent annually between 2007 and 2011. Over the same time period, nuclear generation fell slightly, while natural gas-fired electricity grew by some 3 percent annually and hydropower by 7 percent. Meanwhile, wind-generated electricity grew by a whopping 36 percent each ...

Optimal control of matrix converter based WECS for performance and stability enhancement at low wind speeds
In this paper, optimal control of new wind energy conversion scheme where four-leg improved matrix converter (MC) is used for performance and stability enhancement, particularly for sites where most of the time low wind speeds prevails, has been explained. The power factor at the interface with the grid is controlled by the MC to ensure purely active power injection into the grid for optimal ...
