Hydro-wind-photovoltaic collaborative development suggestions in Southwest China under the dual carbon goals

Abstract

To achieve the dual carbon goals, China urgently needs to build a new power system dominated by clean energy. As a region rich in hydro, wind, and solar resources, Southwest China possesses a solid foundation for clean energy development and serves as a primary area for constructing comprehensive energy bases for hydro-wind-photovoltaic collaboration. Based on the dual carbon goals, current status, opportunities, and challenges of hydro-wind-photovoltaic collaborative development in Southwest China and proposes corresponding countermeasures was explored. The research highlights that Southwest China demonstrates significant advantages in multi-energy complementarity by coordinating the flexible regulation characteristics of hydropower with the intermittent nature of wind and solar power, thereby enhancing the stability of the energy system. To address the challenges of hydro-wind-photovoltaic collaborative development, this study suggests the following measures:(1) promote the integrated development of hydro-wind-solar-storage systems to optimize multi-energy complementarity;(2) accelerate the construction of key reservoirs to enhance regulation capacity;(3) optimize the power transmission system to strengthen interconnection and mutual support;(4) adhere to the principle of ecological priority to achieve green development. The findings provide valuable references for China's energy structure transformation and clean energy development.
