Can a multi-energy complementary power generation system integrate wind and solar energy?

Simulation results validated using real-world data from the southwest region of China. Future research will focus on stochastic modeling and incorporating energy storage systems. This paper proposes constructing a multi-energy complementary power generation system integrating hydropower, wind, and solar energy.

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

How to integrate wind and solar power?

When considering the integration of wind and solar power, increasing the installed capacity of renewable energy while maintaining a certain wind-solar ratio can effectively match the power generation with the user load within a specific range. In engineering design, it is essential to address the issue of ensuring supply from 16:00 to 22:00.

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.

What is the role of cascaded hydropower stations in China?

The southwestern region of China is rich in hydropower and wind energy resources, and cascaded hydropower stations provide a foundation for developing photovoltaic (PV) and wind power projects.

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.
