提出了一种面向智能电网的自治VGT(虚拟发电部落)分散协同控制框架。首先提出了一种基于VGT的协同一致性算法(VGT-CCA),用于解决理想通信网络下自动发电控制(AGC)的动态GCD优化问题。通过引入一致性增益函数和虚拟一致性变量,设计了一种新的CCA VGT-RCCA(VGT based robust CCA),该CCA对由交换拓扑、传输时延和噪声组成的实际通信网络具有显著的鲁棒性。分别在典型的两区负荷频率控制模型和南方电网模型上对VGT-CCA和VGT-RCCA的性能进行了评估。仿真结果验证了所提算法的有效性。
This paper proposes a decentralized collaborative control framework of autonomous VGT (virtual generation tribe) for smart grid. A VGT-CCA (VGT based collaborative consensus algorithm) is firstly developed to solve the dynamic GCD (generation command dispatch) optimization of the AGC (automatic generation control) under an ideal communication network. Then a novel CCA VGT-RCCA (VGT based robust CCA) is designed by introducing the consensus gain functions and virtual consensus variables, which provides significant robustness to a practical communication network consisted with switching topology, transmission delay and noise. The performance of VGT-CCA and VGT-RCCA has been evaluated on a typical two-area load frequency control model and the China southern power grid model, respectively. Simulation results verify the effectiveness of the proposed algorithms.
