ABSTRACT
In general,
the energy storage in facilities to intermittent sources is provided by a battery
of accumulators. Having found that the duration of life of chemical accumulators is strongly
shortened in the northern regions of Cameroon and that this has a considerable
impact on the operating costs and the reliability of power plants to intermittent
sources, this work proposes to find an alternative to these chemical accumulators rendered vulnerable by the high temperatures.
It reviews all energy storage techniques and makes a choice (the CAES (compressed air energy
storage)) based on thermal robustness.
It proposes a new technique of restitution of the energy by producing an artificial
wind from the compressed air. The feedback loop thus obtained by the compressor-tank-wind
subsystem is studied from a series of manipulations and its efficiency is determined.
To automate the operation of this system, a controller is required. The operating logic of the controller is
provided in function of the precise states of the load, the tank and the natural
sources.
