摘要

考虑光伏可通过逆变器以弃光形式参与配电网调节,提出以合理弃光率为约束的配电网光伏多点接入最大容量评估模型,将传统评估模型中配电网接入光伏后运行状态指标不越限或越限概率不超标的约束转化为越限后果不超标的约束。针对海量场景,根据问题自身技术特性和电网运行规律,对模型本身和考虑的场景进行简化,最终使用遗传算法实现了求解。基于IEEE 33节点的算例验证了评估模型和求解算法的有效性,且表明,允许5%的弃光率可提升40%的光伏接入容量,提升效果显著。

Abstract

In the distribution network,photovoltaic（PV） can participate in the voltage regulation through proper power curtailment. In this background, an evaluation model of the maximum PV access capacity in the distribution network is proposed considering multi-point access and the constraint of reasonable power curtailment. The conventional constraint after the distribution network being connected to PV that the operation state index does not exceed the limit or the probability of exceeding the limit does not exceed the limitis is replaced by the constraint that the consequences of exceeding the limits is within an acceptable value. For massive scenarios, the modeland the application scenarios are simplified according to the technical characteristics and the operation laws of the distribution network system. Finally, the problem is solved by genetic algorithm. The effectiveness of the evaluation model andalgorithm is verified on the IEEE 33-bus. Results show that 5% of PV power curtailment can increase PV access capacity about 40%. The improvement effect is significant.
