Solar–wind hybrid renewable energy system: A review

Economic and environmental analysis of a hybrid solar, wind and pumped storage hydroelectric energy source: a Polish perspective

“…The introduction of non-dispatchable generation in the form of solar and wind energy sources leads to a situation in which the supply side also starts to vary and this in turn leads to disruptions on the energy market. Numerous papers has been dedicated to the problem of subjugating variable renewable energy sources (VRES) and easing their integration into the energy system by means of: wind speed [8,9] and irradiation [10,11] forecasting, spatial and temporal complementarity of selected energy sources [12,13], hybrid energy sources [14][15], energy storage options [16,17], and demand side management [18]. Delucci and Jacobson [19,20] state that by combining all the approaches described above and employing additional ones it is possible to cover the world energy demand using solar, wind and hydropower.…”

“…But one would have to overcome the same problems which we face nowadays with the integration of RES, namely, their variable and non-dispatchable nature. As has already been mentioned, several approaches [8][9][10][11][12][13][14][15][16][17][18][19][20] can be applied, but the concept which incorporates at least three of them is a hybrid of photovoltaic (solar power), wind turbine and pumped storage hydroelectricity (PV-WT-PSH).Coupled wind and solar power sources tend to exhibit lower variability and it is well known that on an annual time scale they exhibit a strong complementarity [11,12,[21][22][23][24]. The concept of the temporal complementarity of a dual energy source can be explained by means of two sine functions which depict their variation in energy output; in the case of perfect temporal complementarity they will be out of phase with each other by π/2, or in other words they have a very strong (˗1) negative correlation.…”

Cascaded H-bridge multilevel inverter for renewable energy generation

“…Energy conversion of renewable energy sources with current technology in [1][2] that would offer dependable and efficient electricity facility .In recent years renewable energy system has become significant alternative of conventional electrical energy generation due to increase in fuel prices, limited reserves and environmental issues. The concern stood by conventional energy sources like non availability of fuels and climate change has been addressed in many countries and aiming to increase the development in the renewable energy system [3].Energy generated by the renewable sources can feed local loads and the surplus power can be transferred to the grid with the use of power electronics converter [4] [5].The quality of electrical power transfer between renewable energy sources and grid depends on the quality of voltage/current [6].The voltage and current fed by the converter should be synchronized to grid with Harmonics level defined by IEEE and IEC standard. The integration of renewable source requires proper power control that plays important role for system efficiency and required output of the system.…”

Optimal Placement and Sizing of Wind-Pv Integrated Power Generation by Ant Colony Optimization Technique

“…To determine the wind generator capacity and the number of PV panels needed for the hybrid energy system [4]. The algorithm uses the hourly average wind, insolation and power demand to determine the wind/PV generation capacities required to meet the demand while minimizing an objective function, which will be the total annual cost to the customer.…”
