Genetic algorithms for optimal reactive power compensation of a power system with wind generators based on artificial neural networks

الملخص EN

IIn this paper, we develop a method to maintain an acceptable voltages profile and minimization of active losses of a power system including wind generators in real time.

These tasks are ensured by acting on capacitor and inductance benches implemented in the consuming nodes.

To solve this problem, we minimize an objective function associated to active losses under constraints imposed on the voltages and the reactive productions of the various benches.

The minimization procedure was realised by the use of genetic algorithms (GA).

The major disadvantage of this technique is that it requires a significant computing time thus not making it possible to deal with the problem in real time.

After a training phase, a neural model has the capacity to provide a good estimation of the voltages, the reactive productions and the losses for forecast curves of the load and the wind speed, in real time.
