Abstract
The potential for utilizing clean energy technologies in Egypt is excellent given the abundant solar irradiation and wind resources. This paper provides detailed design, control strategy, and performance evaluation of a grid-connected large-scale PV/wind hybrid power system in Gabel El-Zeit region located along the coast of the Red Sea, Egypt. The proposed hybrid power system consists of 50 MW PV station and 200 MW wind farm and interconnected with the electrical grid through the main Point of Common Coupling (PCC) busbar to enhance the system performance. The hybrid power system is controlled to operate at the unity power factor and also the Maximum Power Point Tracking (MPPT) technique is applied to extract the maximum power during the climatic conditions changes. Modeling and simulation of the hybrid power system have been performed using MATLAB/SIMULINK environment. Moreover, the paper presented a comprehensive case study about the realistic monthly variations of solar irradiance and wind speed in the study region to validate the effectiveness of the proposed MPPT techniques and the used control strategy. The simulation results illustrate that the total annual electricity generation from the hybrid power system is 1509.85 GWh/year, where 118.15 GWh/year (7.83 %) generates from the PV station and 1391.7 GWh/year (92.17%) comes from the wind farm. Furthermore, the hybrid power system successfully operates at the unity power factor since the injected reactive power is kept at zero.
Highlights
Nowadays, the combined utilization of Renewable Energy Sources (RES) such as PV and wind energy is being widely used for substitution of conventional energy resources, and eventually to decrease the combustion of fossil fuels
The proposed hybrid power system consists of 50 MW PV station-based Sanyo HIP-200B PV module and 200 MW wind farm-based Gamesa G80 wind turbine and it is interconnected with the electrical grid through the main Point of Common Coupling (PCC) busbar to enhance the system performance
This section is divided into three parts 1) performance of the PV station under the solar irradiation variation 2) performance of the wind farm during the change of the wind speed 3) hybrid power system performance at the PCC busbar
Summary
The combined utilization of Renewable Energy Sources (RES) such as PV and wind energy is being widely used for substitution of conventional energy resources, and eventually to decrease the combustion of fossil fuels. From the literature survey and to utilize the RES in Egypt, this paper presents the detailed design, control strategy, and performance analysis of a grid-connected large-scale PV/wind hybrid power system in Gabel El-Zeit region located along the coast of the Red Sea, Egypt. This region is endowed with a good level of solar irradiance with an annual average value of 199.75 kWh/m2 and powerful wind speed with an average value of 14.08 m/s at 60 m hub height. The symmetrical factor (α) needs to be in a range between 2 to 4 [24]
