Research on Power System Planning Considering Regional Heterogeneity and Energy Storage Deployment
The deployment of renewable energy plays an important role in enhancing energy structure optimization and facilitating green transformation.Energy storage technology is an essential component for building a system that can accommodate high proportions of re-newable energy electricity consumption.Using Chinese provincial power systems as the research focus,this study characterizes the re-gional heterogeneity of renewable energy by analyzing hourly capacity factors and integrates the provincial power system expansion model with the regional economic dispatch model.The aim of this study is to explore how diverse energy storage technologies impact the con-sumption of renewable energy electricity and the carbon emissions of the power system,while considering the disparities in resource a-vailability.The study finds that,supported by inter-provincial transmission,the Renewable Portfolio Standard significantly encourages the installation of renewable energy and energy storage capacity in regions with abundant resources.This,in turn,facilitates the spatial flow and balanced distribution of renewable energy power.Energy storage technology plays a pivotal role in enhancing renewable energy consumption and reducing carbon emissions.This effect is notably more pronounced in regions with abundant resources,when com-pared to those with poor resources.Influenced by technological cost,the evolutionary trends of diverse energy storage technologies vary significantly.Pumped storage technology is expected to dominate in the medium term by 2030,while battery energy storage systems,such as all-vanadium flow,are likely to lead in the long term by 2050.In summary,when deploying energy storage technology,it is essential to consider the differences in regional resources and technological development.Additionally,the application effect and cost of energy storage must be taken into account to ensure efficient and cost-effective implementation.
