Backstepping controllers are obtained for distributed hybrid photovoltaic (PV) power supplies of telecommunication equipment. Grid-connected PV-based power supply units may contain dc-dc buck-boost converters linked to single-phase inverters. This distributed energy resource operated within the selfconsumption concept can aid in the peak-shaving strategy of ac smart grids. New backstepping control laws are obtained for the single-phase inverter and for the buck-boost converter feeding a telecom equipment/battery while sourcing the PV excess power to the smart grid or to grid supply the telecom system. The backstepping approach is robust and able to cope with the grid nonlinearity and uncertainties providing dc input current and voltage controllers for the buck-boost converter to track the PV panel maximum power point, regulating the PV output dc voltage to extract maximum power; unity power factor sinusoidal ac smart grid inverter currents and constant dc-link voltages suited for telecom equipment; and inverter bidirectional power transfer. Experimental results are obtained from a lab setup controlled by one inexpensive dsPIC running the sampling, the backstepping and modulator algorithms. Results show the controllers guarantee maximum power transfer to the telecom equipment/ac grid, ensuring steady dc-link voltage while absorbing/injecting low harmonic distortion current into the smart grid.

“…Gomaa et al (1995) studied energy generation based on a hybrid system of solar PV cells and WT for a site in Alexandria. Zahran et al (2000) introduced a hybrid system that consists of PV cells, battery and WT to power up a telecommunication equipment. Ghali and Arafah (2002) designed a three-level inverter to suppress harmonics induced to heterogeneous sources in a hybrid system of WT and diesel generators.…”

Energy is a cornerstone for achieving industrial development and prosperous economy. Wind energy has the biggest share of renewable energy sector in many countries leading the way for replacing fossil fuels. Egypt, as one of the developing countries, is heading towards increasing penetration levels of wind power to face energy challenges. This strategy takes advantage of the investigated high potential of wind energy in several locations across Egypt. In order to gain most benefits and economical revenues from wind energy, a national research and development policies have to be deployed. Effective research policies enhance the capabilities of local industry for wind power technology. This review characterises current progress and categorises areas of interest for recent research of wind energy in Egypt. Accordingly, a vision for existing gaps, futuristic directions and promising areas for research is formulated.

“…Especially, solar and wind energy are infinite, non-polluting and complementary with each other. Hybrid solar-wind systems are also suited to reduce dependence on fossil fuel using available wind speed and solar irirradiations [7]. So, PV modules and wind turbines are widely preferred in locations where it might be inconvenient or expensive to use conventional grid supplies [12].…”

—Hybrid power system consists of different sources of electrical energy with different operating times during different seasons. Deployment of a hybrid power system is expected in rural areas. Supplying remote load systems such as rural telephony, hospitals, military etc.., where continuous power supply is required, can be realized with the combination of wind and solar power. The proposed topology is designed for telecom load which uses dual input dc-dc fused converter for combining solar and wind energy sources. For the further research and improvements in the proposed fused converter topology, it is necessary to know in detail the power flow from solar and wind sources to the load or to storage battery depending on different seasons. For various wind speed with constant solar irirradiation and, for various solar irirradiations with constant wind speed, the power flow of the hybrid power system is simulated and presented. The same topology is investigated for different switching frequencies (10 kHz and 20 kHz), using MATLAB/SIMULINK, and the efficiencies are calculated.
