Fig 4.4 Household / Parastatal Energy Consumption Pattern

Fig 4.4 Shows the household parastal energy consumption pattern. It shows that when the power rating is 1000w the number of quatity used is 1.On the other hand when the rating is 60w the quantity is 1.6
CHAPTER FIVE
CONCLUSION
5.1 General conclusion
The following sequential steps were used to achieve the impact of integrating renewable energy sources for rural electrification optimization using an intelligent agent determining available sources of renewable energy in Amoli community, analysizing the energy demand for a cluster of building/facilities in Amoli community, optimizing the energy demand for a cluster of building facilities in Amoli, designing an optimized intelligent agent for an effective power stability,Createing a chart of the required number of recommended energy system to meet the various energy demand level., designing a Simulink model for the impact of integrating renewable energy sources for rural electrification optimization using an intelligent agent.

5.2 Findings
I Harmonic distortion causes unstable power supply.
ii Overcurrnt, overvoltage, causes instability of power supply.
iii Stability of power supply in rural areas will enhance development.
iv Stable power supply creats employment opportunity.

5.3 Recommendations
In near future there should be an introduction of an optimized intelligent agent incorporated in the grid for a stable power supply.
