考虑短时波动的分布式光伏逆变器鲁棒集中-就地控制策略
Robust Centralized-local Control Strategy of Distributed Photovoltaic Inverter Considering Short-time Fluctuation
摘要
Abstract
In allusion to the problem that the centralized con-trol of photovoltaic inverter takes into account the short-term fluctuations of source and load deficiently,a robust centralized-local control strategy was proposed.Firstly,taking minimizing network loss and light rejection as an object,centralized active and reactive power control model was established;In view of the voltage out of limit and power flow fluctuation caused by the short-term fluctuation in the control interval,a three para-meter centralized-local control model of reactive power output-active power reduction-slope parameter was proposed based on the centralized control results.Secondly,the interval model was used to model short-term fluctuations,and the robust optimiza-tion model of local control strategy was established to minim-ize the voltage deviation in extreme fluctuation scenarios.Fi-nally,solution method of control strategy based on second-or-der cone programming and sensitivity analysis was proposed.The validity of proposed model was verified by a numerical ex-ample,and the influence of fluctuation,permeability and invert-er capacity on the control was analyzed to improve the opera-tion safety and economy of the active distribution system.关键词
