Using an OPF like Approach to Define the Operational Strategy of a Wind Park under a System Operator Control

This paper presents a formulation for an Optimal Power Flow problem that includes the DFIG wind generator reactive power characteristics in order to obtain set points that consider wind turbines loading capabilities. This approach can be adopted at the wind park control level to define the active and reactive set points following requests from the wind park dispatch centers.

Synchrophasors for load modelling in Australia

The inherent low noise of PMU measurements means that small variations in a power system can reliably indicate aspects of system performance. This factor combined with the continual customer load variation and its randomness properties permits the identification of system dynamics. The same variation combined with an understanding of the key parameters of load dynamics opens the possibilities of on-line load dynamic identification. Even though the normal variations in voltages and frequencies are small, this paper summarizes how the key properties of PMU signals open a new field of power system identification. Results are given for both synthetic data and real data from the power system.

Unit Commitment and Dispatch Strategies for a Wind Park

This paper presents an optimization strategy to be adopted at wind park control level. This approach transposes the classical formulations of a unit commitment and a generator dispatch problem to the turbines of a wind park, assuming that variable speed wind turbines are installed, and considering that wind speed forecasts are available. Wind speed forecasts, demands from grid operators or generation levels defined to comply with market strategies are the inputs of the problem. A small example is used to illustrate the proposed approach.
