Optimization of Hybrid PV/Diesel Power System for Remote Telecom Station

ABSTRACT Photovoltaic system is an important topic that can be researched and studied in Iraq because a solar energy potential is available. This paper deals with the design of PV system for electrification of remote communication towers in a mobile company in Iraq , design of solar hybrid power generation system connected to the tower loads .This hybrid system consists of photovoltaic system, diesel generator , power flow controller, power electronic converter and the tower loads. The main strategy of the system will be if there is enough energy from the sun , the load demands can be supplied from these sources. Whenever there is excess supply from the renewable energy sources, the energy will storage in special batteries. If either the available power from the solar panels cannot satisfy the load demand, the generator can meet the excess power demand. The main objective is to estimate the economical and environmental impact of using solar PV hybrid system instead of diesel generators, estimated for both running and fixed costs. The related environmental impacts are discussed from the sustainable development point of view, the using of PV solar energy systems in two mentioned locations it can be saved around 27,000 kg CO2, which is emphasize on the future role of renewable energy sources in Iraq.
