Solar energy generation is contingent upon daylight and clear weather conditions, whereas wind energy is unpredictable, depending on fluctuating wind speeds. The intermittency and variability of these energy sources pose a challenge to the stability of the electricity grid, thereby affecting the wider adoption of renewable energy systems.
Despite the individual merits of solar and wind energy systems, their intermittent nature and geographical limitations have spurred interest in hybrid solutions that maximize efficiency and reliability through integrated systems.
The annual wind energy production is 123 MWh, with a grid energy requirement of only 9.5 MWh to satisfy the load demand. Figure 14. GC2—Wind + PSH + Grid yearly balance: (a) energy balance, (b) water balance, (c)energy by sources, (d) power data, and (e) statistics (between percentile 25 and 75%). 3.3. Economic and Environmental Assessment
However, such systems mitigate the intermittency issues inherent to individual renewable sources, enhancing the overall reliability and stability of energy generation. Solar power exhibits peak output during daylight hours, while wind power can be harnessed even during periods of reduced solar availability .
The most common configurations are solar-wind, wind-hydro, and solar-hydro combinations. The selection of the configuration depends on the availability and variability of the renewable energy sources, the power demand, and the geographical location of the system. 3.4. HRES without storage units
For on-grid applications, combining wind and solar can also offer advantages. One primary benefit is grid stability. Fluctuations in renewable energy supply can be problematic for maintaining a stable, consistent energy supply on the grid. The hybrid system can help mitigate this issue by providing a more constant power output.
