This paper analyses the technical and economic feasibility of using a hybrid renewable energy source for a typical telecom load in the state of Qatar. The hybrid system considered in this work consists of a solar photovoltaic with storage battery and diesel generator set. For this particular hybrid system, the meteorological data of solar irradiance in Doha city (latitude 25.15°North and longitude 51.33°East) are taken from NASA surface meteorology and solar energy websites. The solar irradiance in Doha is 5.33 kWh/m 2 /day on an annual average scale. The data are also taken through the study of load consumption of Qatar telecommunication hybrid power system. The system is designed and its techno-economic analysis is carried out using the Hybrid Optimization Model for Electrical Renewable software. The results show both technical and economic viability of replacing the conventional DG sets with the proposed renewable energy source.

“…The operational principle of HB-ZVR topology is very similar to the HERIC topology [72]. The gate pulse of S5 in the positive half-wave is the contrary gate pulse of S1 and S4, with a small dead time to neglect grid short circuit [25,76]. During the negative half wave, S5 is controlled using the contrary gate pulse of S2 and S3 and creates zero-voltage state by short-circuiting the output of the inverter and clamping them to the mid-point of the DC bus.…”

a b s t r a c tGrid-tied inverters are the key components of distributed generation system because of their function as an effective interface between renewable energy sources and utility. Recently, there has been an increasing interest in the use of transformerless inverter for low-voltage single-phase grid-tied photovoltaic (PV) system due to higher efficiency, lower cost, smaller size and weight when compared to the ones with transformer. However, the leakage current issues of transformerless inverter, which depends on the topology structure and modulation scheme, have to be addressed very carefully. This review focuses on the transformerless topologies, which are classified into three basic groups based on the decoupling method and leakage current characteristics. Different topologies under the three classes are presented, compared and evaluated based on leakage current, component ratings, advantages, and disadvantages. An examination of demand for the inverter, the utility grid, and the PV module are presented. A performance comparison in MATLAB/Simulink environment is done among different topologies. Also an analysis has been presented to select a better topology. Finally, based on the analysis and simulation results, a comparison table has been presented. Furthermore, some important experimental parameters have been summarized.

“…To deliver power either directly or indirectly (grid-tied) from those power sources to the load, a power interface is required for power conversion. Nowadays, some researchers pay more attention to this power conversion by developing inverter topologies with simple structures and proposing control strategies with easy implementation [1][2][3][4][5][6].…”

A differential boost inverter (DBI) consists of two bidirectional boost converters and has a differential sinusoidal output voltage. This output voltage is obtained because each bidirectional boost converters generates a dc-biased sinusoidal voltage. Owing to this characteristic, this inverter topology requires a controller that can track a dc-biased sinusoidal voltage as the control reference. One cycle control (OCC) is a non-linear control approach that can meet the requirements and be easily implemented in a simple circuit with constant switching frequency. The controller must be capable of achieving a unity power factor (PF) because the inverter is designed to deliver maximum active power to the grid. Therefore, the sinusoidal reference signal of the OCC is formed by the scaled grid voltage and its derivation. Given this reference signal, the inverter output voltage represents the grid voltage with a small variation phase and amplitude. Furthermore, this strategy will guarantee that the output current and the grid voltage are in phase. An experimental prototype of DBI is implemented to verify that the control approach can achieve PF close to unity such that the maximum active power can be delivered to the grid with minimum current total harmonic distortion.
