Abstract

The control of a set of hydro-power plants with or without reservoirs is taken into account. Even if the water input flows vary significantly, the lake levels have to be constrained and the power generation should be preferentially provided during the demanded peak hours. Each power station has assigned a local controller capable to communicate with its neighbor controllers. The proposed genetic programming method automatically generates a distributed Time Petri Net (TPN) that is capable to minimize the lake level variations and to update the decisions to start the generator(s) with the input flow levels. The cooperation of neighbor controllers improves the local control decisions taking into account the neighbor decisions and so reducing the daily generator start number.
