摘要/Abstract

摘要：

为了在确保配电网安全、稳定运行的同时,促进配电网分布式光伏消纳,文章提出了一种主动配电网分布式光伏最大准入容量计算方法。以最大化分布式光伏准入容量为目标,计及系统潮流方程、节点电压、支路电流等多个电气约束,采用有载调压、无功补偿、储能充放电、网络重构、负荷削减等主动管理措施和需求侧管理措施,提升了“源荷”不确定性最不利条件下分布式光伏最大准入容量,建立了二阶段鲁棒优化模型。将原模型分解为主问题与子问题后,转化为混合整数二阶锥形式,使用列与约束生成算法求解。在改进的IEEE 33节点算例上对模型与算法的有效性进行检验,得到了主动配电网分布式光伏最大准入容量,并验证了主动管理与需求侧管理对其的提升作用。

Abstract:

This paper proposes a method to calculate the maximum allowable access capacity of distributed photovoltaic (PV) generation in an active distribution network (ADN), in order to facilitate the usage of the distributed PV on the premise of system security and stability. The objective is to maximize the allowable access capacity of distributed PV. Several electrical constraints, including power flow equations, bus voltage limits, branch current limits, etc., are taken into account. Furthermore, active management (AM) and demand-side management (DSM) techniques including on-load voltage regulation, reactive power compensation, control of the battery energy storage system, network reconfiguration and load curtailment are applied to increase the access capacity under the worse uncertainty condition. A two-stage robust optimization model is established. The model can be decomposed into a master problem and a subproblem in the form of mixed integer second order cones, and solved by column-and-constraint generation algorithm. A case study is implemented on the modified IEEE 33-node system to verify the validation of the proposed model and algorithm. The maximum allowable access capacity of distributed PV can be obtained. The enhancement of the result is achieved through AM and DSM techniques.

Key words: active management, demand-side management, distributed photovoltaic generation, maximum allowable access capacity, robust optimization
