Including the Optimization Method of High-Proportion Distributed Photovoltaic Distribution Grid Subdivision Voltage Adjustment Coefficient
摘要
Abstract
[Objective]To improve the reactive response of photovoltaics and limit the problem of voltage overlimit,a subdivision-based reactive voltage adjustment coefficient optimization method is proposed considering a large number of distributed photovoltaics connected to the grid.[Methods]To limit the voltage fluctuations of each node under various scenarios,an optimization model of nodes with reactive voltage differential coefficients based on partitions is proposed.The control model is simplified by using the characteristics of"strong coupling within the interval and weak coupling between partitions"to realize that photovoltaics can independently adjust the reactive output according to external voltage fluctuations and make full use of the reactive residual.[Results]The simulation results of the IEEE 33 node standard example show that the partition-based reactive voltage adjustment coefficient optimization method can effectively use the reactive to regulate node voltage,which is more conducive to meeting the requirements of accuracy and speed of reactive optimization.[Conclusions]The method proposed in this study can effectively improve the voltage quality of distribution grid nodes under various scenarios,effectively utilizing the photovoltaic reactive residual.关键词
