摘要:

随着可再生能源大规模接入,以及区域间电力需求差异日益显著,现有规划方法多局限于单一区域或源-网-储局部协同,难以适应跨区域电力互补与广域协同运行的需求。聚焦面向多区域电网电力错峰互济的源-网-储广域协同规划难题,提出一种融合多时空尺度耦合建模、跨区域互补特性挖掘与协同优化机制的新型规划框架。首先,构建考虑气候差异与负荷时序特性的多区域源-网-储联合模型,采用Copula理论生成风光联合出力场景集,量化分析各区域电力时序错峰潜力;其次,构建以总成本最小为目标的广域协同规划模型,统筹电源、电网与储能的协同配置;最后,引入鲁棒-随机混合优化方法,应对新能源出力与跨区输电能力的多重不确定性。以我国“三北”与华东多区域互联电网为实例进行仿真验证,结果表明,规划后系统可再生能源发电量占比提升至93.1%,其中风电与光伏贡献69.3%的发电量,系统综合成本降低8.5%,跨区互济能力增强约15.0%,为实现多区域电力系统低碳、高效、安全协同发展提供理论支撑与技术路径。

Abstract:

With the large-scale integration of renewable energy and increasingly prominent inter-regional power demand differences, existing planning methods are mostly limited to single regions or local generation-grid-storage coordination, which cannot meet the requirements of cross-regional power complementation and wide-area coordinated operation. Aiming at the wide-area coordinated planning difficulty of generation-grid-storage oriented to multi-regional power peak shaving and mutual power support, a novel planning framework integrating multi-temporal-spatial scale coupled modeling, cross-regional complementary characteristic mining and collaborative optimization mechanism is proposed. Firstly, a multi-regional joint generation-grid-storage model considering climatic differences and time-series load characteristics is established. The Copula theory is adopted to generate wind-solar joint output scenario sets and quantitatively quantify the time-series peak shaving potential of each region. Secondly, a wide-area coordinated planning model with the objective of minimizing total system cost is built to realize coordinated allocation of power sources, power grids and energy storage facilities. Finally, a robust-stochastic hybrid optimization method is introduced to cope with multiple uncertainties of renewable energy output and cross-regional transmission capacity. Taking the interconnected multi-regional power grids of China's Three-North Region and East China as the example, simulation verification is carried out. The results show that after optimal planning, the proportion of renewable energy power generation of the system rises to 93.1%, among which wind and photovoltaic power account for 69.3% of total power generation. The overall system cost is reduced by 8.5%, and the cross-regional mutual power support capacity is increased by approximately 15.0%. The research provides theoretical support and technical approaches for realizing low-carbon, high-efficiency and secure coordinated development of multi-regional power systems.

Key words: novel power system, flexible supply-demand balance, generation-grid-storage coordination, regional mutual power support
