大规模风电接入电网的有功分层模型预测控制方法

A Hierarchical Model Predictive Control Method of Active Power for Accommodating Large-scale Wind Power Integration

随着电力系统规模的不断扩大及大规模间歇性可再生能源发电的接入,传统的电力系统有功调度控制方法面临挑战,需要引入新的控制理论和方法。对此,借鉴工业过程控制中的模型预测控制和大系统分层递阶控制,提出分层模型预测控制方法用于大规模风电接入电力系统的有功调度控制。给出了方法的演化过程,阐明了方法的控制机理。

With the ever-increasing size of the power grid and the large-scale integration of stochastic renewable energy,the conventional active power dispatch method has become inapplicable.Therefore,a model predictive control (MPC) based method is proposed to deal with the stochastic characteristic of the grid.Meanwhile,a multi-layer MPC scheme using the industrial large system hierarchical control strategy as a source of reference is adopted to deal with the difficult active power dispatch problem with large-scale wind power integration.The evolutionary process and the corresponding control mechanism of the proposed control scheme are given.
