计及水电特性的青海多能互补储能优化配置
Optimal configuration of multi-energy complementary energy storage in Qinghai accounting for hydropower characteristics
摘要
Abstract
To address the combined challenges of wind-solar power fluctuations and seasonal hydropower disparities in the Qinghai grid under high renewable energy penetration,this paper presents a bi-level optimization model for energy storage capacity planning.The model explicitly considers the patterns of hydropower output and its complementarity with renewable energy by incorporating time-dependent operational constraints that quantify these characteristics.For a typical year,the optimized storage configuration in the scenario under certain time-segmented hydropower constraints is 526 MW/1578 MWh with a 3-hour duration,achieving a 91%renewable energy utilization rate.This rate is higher than the ones of 84%,88%,and 86%achieved by the hydropower operations under no constraint,annual wide-constraint,and annual narrow-constraint,respectively.It verifies that our novel method that represents the hydropower features using quantified constraints enhances its rationality and applicability in practical applications of the storage configuration,thereby supporting higher renewable energy integration.关键词
