| 中文摘要: |
| 虚拟电厂通过聚合配电网中的海量分布式资源,构建灵活聚合体以参与电力市场调节和电网调度,助力解决供需平衡问题。然而,现有虚拟电厂的能量管理策略中,如何有效兼顾配电网的运行安全仍是亟待突破的关键难题。为实现虚拟电厂内分布式资源的高效协调与电网安全运行的双重目标,配电网安全域理论被用于构建一种动态的虚拟电厂分布式能量管理策略。首先基于配电网潮流拓扑构建安全域模型,随后采用一致性算法设计虚拟电厂内部资源的自治调度框架,并通过引入基于安全域边界函数的安全一致性变量,兼顾经济性与安全性需求,从而实现考虑电网安全约束下的虚拟电厂分布式能量管理。算例分析结果表明,配电网潮流的安全性被有效保障,虚拟电厂内部资源可快速、准确、动态调控。 |

| By aggregating massive distributed resources in distribution networks, virtual power plants (VPPs) are formed to create flexible portfolios used in electricity market regulation and grid dispatching, thereby addressing power supply-demand imbalances. However, in existing VPP energy management strategies, the effective consideration of distribution network operational security remains a key challenge. To achieve both efficient coordination of distributed resources within VPPs and secure operation of distribution networks, the distribution network security-region theory is adopted, whereby a dynamic distributed energy management strategy is constructed. A security-region model is first established based on the power-flow topology, and a decentralized scheduling framework is then designed for internal VPP resources using a consensus algorithm. By introducing a security-consensus variable defined by the security-region boundary function, economic and security requirements are jointly satisfied, enabling distributed energy management under network security constraints. Case studies show that the security of distribution network power flows is effectively ensured, and internal VPP resources are regulated rapidly, accurately, and dynamically. |
