储能在新型电力系统构建中的作用定位与价值探讨OA

The development of new-type power systems has raised an urgent demand for energy storage.As the construction of energy storage moves toward market-oriented approaches,it is of great significance to identify the role of energy storage in new-type power systems and to explore its indispensable and unique value,which also supports the development of energy storage,the construction of new-type power systems,and the realization of carbon neutrality goals.First,we revisit the research and development of energy storage in power systems,conclude its applications in generation-side,grid-side,and demand-side,and provide corresponding configuration suggestions.Then,considering the two main characteristics of new-type power systems(namely,high levels of renewables and high levels of power electronics),we propose two corresponding overall solution approaches,i.e.,spatial-temporal flexible power balance across generation-storage-demand and active grid-strength support by energy storage,respectively,and discuss the role and value of energy storage in the two approaches.Finally,we further investigate the value of energy storage under the background of nationwide integrated power markets and propose the new concepts of system-owned energy storage and strength markets,based on which we provide suggestions on the future research of energy storage in power systems.
