Our study which we undertake here is the modelling of a system composed of a wind turbine, an energy storage device and an energy well.
It is a well-known fact that the world economy is based on the energy consumption, and a major source of nowadays anxiety in our modern society is the growth of scientific studies that announce alarming climate changes and the significant decrease of fossil resources. Nevertheless, green technologies are soaring and theories with them also are. For instance, windmill plant implantations have been thought on a big scale. Those are generally connected to the general network and the electricity so produced is sold to general providers. Nevertheless, we would like to study this question with another point of view. Perhaps the macro-approach for those types of installations is not the most optimised one. A closer look has to be given to the micro-approach.
Our study which we undertake here is the modelling of a system composed of a wind turbine, an energy storage device and an energy well. This closed system is a function of two variables, the windmill’s diameter and the maximum capacity of the energy storage device. This system is subjected to two external factors, the wind and the energy consumption (i.e. energy well, e.g. a domestic consumption) wired to the system. Those two variables are stochastic inputs which are modelled following two different probabilistic distributions.
The first final output of the system, the probability of loss of power supply, will be obtained after running a simulation inspired by a Monte Carlo method. A second output, the minimum price for a specified installation (i.e. a diameter, a maximum capacity and a probability of loss of power supply all fixed) will be discovered.
The results expected with this paper are twofold. The first is to determine if an installation like ours is economic viability for domestic purpose, and then secondly demonstrate that perhaps the best solution to respond to a national electric demand is not to build huge grids but instead to turn towards independent and localized installations.
