Preferred Abstract (Original):

Integrating renewable energy resources such as photovoltaic system with diesel generator in a hybrid power system is widely spread in the worldwide due to the economic and technical aspects. These systems prove their feasibility in the remote areas, where the grid extension is not available. An optimum dispatch strategy for these systems is a very important factor that affects the cost of the energy generated. Therefore, the main objective of this review is to show the state of art of hybrid photovoltaic/diesel generator system control strategies. Research work in the period of 1998–2014 is covered and analyzed. In addition to that, a summary of the latest technologies in this field is provided. Finally, challenges to this science are concluded. These challenges are accurate estimation of load demand and meteorological data, system performance prediction, system’s component models, optimal sizing of the system and operation set points optimization. In optimizing the operation set points there are many aspects to consider such as system reliability, emitted emission by the system and the cost of the energy generated.

Preferred Abstract (Original):

Hybrid power systems are based on renewable energysources and especially on photovoltaic and wind energy systems.Software package is used to analyze measuring data for windspeed and solar radiation of two locations in Palestine(Ramallah and Nablus). Results of analysis illustrate thatenergy density available in wind for Ramallah site is about 2008 kWh/ mP2.year, while it is 927 kWh/m2 .year for Nablus site. Thedaily average of solar radiation intensity on horizontal surfaceis about 5.4 kWh/m2 .day. A Matlab software package is used to simulate different scenarios of operation of the hybrid system by making energy balance calculations on an hourly basis foreach of the 8760 hours in a year. This enable to choose the appropriate sizes of the different components for the most optimum scenario. The optimization is based on cost of generation. Results of the simulation illustrate that the most economic scenario is the scenario that uses a hybrid systemmainly dependent on wind. Cost of energy (COE) in thisscenario is 1.28 NIS/kWh(͠ 0.35 $/kWh). Other scenariosdependent on wind-diesel hybrid system, PV-diesel hybrid system, wind stand-alone system, PV stand-alone system, or diesel only, give results of COE greater than this value. It wasconcluded that none of the hybrid system scenarios analyzedcould be justified to replace purchasing of electricity from thegrid where the COE is 0.70 NIS/kWh(0.19 $/kWh).
