What are the complementary characteristics of wind and solar energy?
The complementary characteristics of wind and solar energy can be fully utilized, which better aligns with fluctuations in user loads, promoting the integration of wind and solar resources and ensuring the safe and stable operation of the system. 1. Introduction
Do wind and solar power complement each other well?
It is clear that regardless of the wind and solar curtailment rate, the optimal installed capacity ratio is close to 1:1. This indicates that wind power and solar power complement each other well based on typical daily output data selected from the entire year, thereby demonstrating the necessity of simultaneous development of wind and solar power.
Is a multi-energy complementary wind-solar-hydropower system optimal?
This study constructed a multi-energy complementary wind-solar-hydropower system model to optimize the capacity configuration of wind, solar, and hydropower, and analyzed the system's performance under different wind-solar ratios. The results show that when the wind-solar ratio is 1.25:1, the overall system performance is optimal.
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.
Does integrated hydro-wind-solar power generation reduce the waste of wind and solar energy?
The results indicate that in the integrated hydro-wind-solar power generation system, hydroelectric power reduces its output when wind and solar power generation is high, thereby minimizing the waste of wind and solar energy.
What is the maximum integration capacity of wind and solar power?
At this ratio, the maximum wind-solar integration capacity reaches 3938.63 MW, with a curtailment rate of wind and solar power kept below 3 % and a loss of load probability maintained at 0 %. Furthermore, under varying loss of load probabilities, the total integration capacity of wind and solar power increases significantly.
