Introduction Buildings account for the first energy user in France with 44% of the total energy consumption and 19% of the green house gas emissions (ADEME and INSEE [1,2]).
Figure 1 shows the countries the most using this technology in Europe [8-11].
∆t (1) Where: ck is the energy price at time step k, Pmax is the maximum available power for the whole district.

S and K are defined in Eq.1
The result of the Gaussian and non-Gaussian stochastic simulation is shown in Fig.1.
However, after the second phase modulation, there is an obvious shock waveform of the non-Gaussian signal, as show in Fig.1 (c) and (d).

Experimental Method The experimental apparatus is presented in Fig.1.
Those solidified ingots were sectioned along the broad side, then polished and etched by a acid solution (HF: HNO3: H2O=1: 1: 20).
