Wind-solar-storage capacity ratio design

What is wind-to-solar capacity ratio?

The wind-to-solar capacity ratio for the maximum installable capacity of the system is around 1.25:1. This indicates that setting the loss of load rate at 3 % during the design phase allows the complementary characteristics of wind and solar power to be fully utilized, making it more suitable for dealing with fluctuations in user load.

How reliable are wind-solar capacity ratios?

These impacts suggest that optimizing wind-solar capacity ratios using data from any single year is reliable, but multi-year renewable energy resources should be considered when designing hydrogen storage tank capacity.

What is the optimal design for a wind-solar-hydrogen storage system?

The optimal design proposed achieved the lowest energy storage capacity and energy cost in the wind-solar-hydrogen storage system. Compared to the scenario with wind power operating independently, the optimal design reduced electricity costs by 40 %, with hydrogen storage tank costs decreasing by 52 %.

What is the maximum wind and solar installed capacity?

The results indicate that a wind-solar ratio of around 1.25:1, with wind power installed capacity of 2350 MW and photovoltaic installed capacity of 1898 MW, results in maximum wind and solar installed capacity. Furthermore, installed capacity increases with increasing wind and solar curtailment rates and loss-of-load probabilities.

How does wind power affect energy storage systems?

Since wind power can still provide some electricity output at night, it effectively compensates for the inability of PV systems to generate power during this period. This significantly reduces the operational duration of energy storage systems and enhances the overall stability of the hybrid system. Fig. 10.

How to optimize wind and solar energy integration?

The optimization uses a particle swarm algorithm to obtain wind and solar energy integration's optimal ratio and capacity configuration. The results indicate that a wind-solar ratio of around 1.25:1, with wind power installed capacity of 2350 MW and photovoltaic installed capacity of 1898 MW, results in maximum wind and solar installed capacity.
