The total conductivities at 800oC were 3.8 × 10-3 S·cm-1 (x = 0), 8.0 × 10-3 S· cm-1 (x = 0.1), 2.5 × 10-2 S· cm-1 (x = 0.2), 1.36 × 10-2 S ·cm-1 (x = 0.3).
For x=0 sample, there appears two peaks 508 cm-1 and 415 cm-1 , which move to lower frequencies (495 cm-1,415 cm-1) in x=0.1 sample.
There is only one peak in higher dopant samples (x=0.2, 0.3) between 400-650 cm-1 and two peaks (near to 1426 cm-1, 858 cm-1).

Results and Discussion
The tables 1, 2, 3 and 4 show the obtained results in this study for the values of hardness and modulus of elasticity of the composites in groups G1 and G2.
Table 1- G1- Composite Z350 - modulus of elasticity (GPa), standard deviation (SD) and statistical analysis with variable load and holdtime.
The superior loads of 50gf and 100gf resulted for groups 1 and 2 more stable and homogeneous values of modulus of elasticity and hardness.

Therefore, the grid-connected inverters play an important role in the distributed generation systems [1]–[4].
(6) The voltages ud* and uq* can be obtained from Fig. 1
Therefore, the voltages ud* and uq* cannot directly reflect the change of p* and q* from (7), (8), and Fig. 1, which causes low dynamic response.
