水风光一体化基地中调节电源定位作用的思考OA

Hydro-solar-wind integration is a crucial approach for promoting the development of new energy.The study suggests that,due to differences in power transmission directions and grid connection methods,integrated energy bases can generally be categorized into two types:those weakly connected to the receiving-end grid via long-distance HVDC lines,and those strongly connected via AC lines.Based on this classification,the functional roles of pumped storage and hydroelectric power in different types of bases are systematically analyzed,highlighting both their similarities and distinct aspects.In weakly connected outbound transmission bases,regulating power sources primarily serve to support the DC transmission curve,while in strongly connected bases for internal demand,they not only complement new energy but also prioritize power system supply-demand balance and stability requirements.The study further recommends that power development tasks should be formulated differently according to the base type.The research findings provide a reference for the planning,research and design of regulating power sources in future hydro-solar-wind integrated energy bases.
