| 摘要: |
| 与传统配电网不同，接入主动配电网的可控分布式电源能够参与配电网的经济运行。可控分布式电源的出力分配由主动配电网的经济调度策略确定。为实现供电能力最大化，可控分布式电源通常运行在额定状态，这与经济运行的目标相背离。这一矛盾会对最大供电能力计算带来影响。提出一种基于机会约束规划的主动配电网最大供电能力双层优化模型。上层模型用于求解主动配电网的最大供电能力；下层模型在负荷增长的过程中结合主动配电网对可控分布式电源有效管理的特点，对可控分布式电源出力按经济调度原则进行分配。以改进IEEE-33配电系统为例对该模型进行验证，结果表明该模型可获得符合主动配电网经济运行要求的最大供电能力。 |

| Abstract: |
| Different from traditional distribution network, the controllable distributed generations assessed to Active Distribution Network (ADN) could participate in the economic operation of distribution network. The output allocation of controllable distributed generations is determined by the economic schedule strategy for ADN. In order to maximize Load Supplying Capability (LSC), controllable distributed generations usually work at rated state, which departs from the pursuit of economic operation. The contradiction has an impact on LSC. This paper highlights a bi-level optimization model for LSC of ADN based on chance-constrained programming. The upper-level model aims at calculating the LSC of ADN, and the lower-level model is to allocate the output of controllable distributed generations based on economic dispatch principle combining the characteristics of ADN effectively managing controllable distributed generations during the process of load growth. Finally, the modified IEEE 33-bus distribution system is taken as an example for verifying the proposed model. The results show that the LSC which meets the requirements of ADN economic operation is acquired.
