Abstract : Regarding importance of security and safety in all countries around the world, the work of the security men requires the use of all means of Wire and wireless communication to control and monitor the security situation around the clock. So, there are remote Areas within the country such as deserts, mountains and maritime islands takes a long time to arrive to it after trouble and hardship. At those locations, towers and communication devices work on generators powered by diesel but the main problem is the sudden interruption of these generators may cause disruption to the communication devices. And the period of interruption may be an opportunity for intruder to enter across borders or for terrorist person in carrying out his plans. So, we had to resort to renewable energy for a stable and sustainable energy working permanently to nurture communication devices while backup generators in case of a defect in a renewable energy system. Through the renewable energy will solve many problems including sudden interruption of communication devices that may cause security problems, reducing the cost of fuel, the cost of spare parts. The research aims in using optimal combination of solar energy and diesel fuel in a system used in remote areas, the system can provide the electrical power all time without any trouble because it works in perfect way when the diesel fuel runs out the system will use the electrical power which produced by solar energy in automatically. Conclusion After studying and continuing work in this thesis, a number of important results have been concluded as follows: The remote areas in Saudi Arabia suffer from breakdown in electrical power because of its distance from the main grid, so it is important to provide these areas with multiple of electrical power generator to support the system with load demand of electrical power and avoid any unexpected breakdown in electrical power. The electrical power system in remote areas based on diesel generator to provide the system in load demand of electrical power, the cost of diesel is high and cause heavy load in money lost to support the diesel generator, so the thesis interested in studying renewable source of power generation. Solar energy has been selected as a renewable energy source for generating electrical power in remote areas, it is free and readily available in Saudi Arabia. The temperatures arrive to 40 Celsius degree, so it can used to provide electrical power with highly efficient. Hybrid system is used to solve the research problem in providing the electrical power at remote areas with the least cost. The thesis study design hybrid system consists of solar energy and diesel generator, the hybrid system based on solar energy as mainly then diesel generator as secondary. MATLAB program had been used to achieve the thesis idea in building hybrid system include PV system and diesel generator. MATLAB software used to design the system and simulate it to show the results and study the performance for the PV and diesel generator systems. After operating hybrid system in project part 1 using MATLAB program the analysis result of PV and diesel system shown the difference between the resulted voltage of solar cells and diesel generator; the voltage in PV system equal 79 volt but in diesel generator system the voltage equal 190 volt. to solve this problem the configuration 57 filter in diesel generator converter was controlled to get the load demand of electrical power in the system. In the project part 2 the voltage value was managed to get 79 volts in each system.
