A model to solve maximum power supply capability of urban distribution network is proposed, which is based on linear programming model of DC power flow. 提出了一种求解城市电网最大供电能力指标的模型,该模型是一种基于直流潮流的线性规划模型,以网络所能供应的最大负荷为目标函数,以网络的功率平衡、各...
On current days, many of the power markets are adopting the practice of marginal loss pricing. The DC optimal power flow (DCOPF) model is still mostly used for the purpose of market clearing owing to its simplicity, robustness and higher speed of convergence. Within the DCOPF framework, tran...
This chapter first reviews briefly how to compute DC power flows. Then the blackouts and SOC phenomena in the Northeast Power Grid of China are discussed so that one can apply the blackout model to this power grid based on DC power flows. Consequently, we are able to identify the relationsh...

This paper presents a unified power-flow model of ac power systems incorporating voltage-sourced converter (VSC) based multi-terminal high voltage direct current (MTDC) grids. Offshore wind farms (OWFs) are appropriately interfaced with the MTDC grid(s). Pulsewidth modulation control is employed ...
Fig. 1 illustrates a typical interconnection of a two-terminal HVDC system with VSCs for off-shore wind power generation. Several control strategies have been proposed, such as the model predictive approach [24], passivity-based control design [25], [26], classical proportional--integral (PI)...
The quadratic expression of unified power flow controller (UPFC) is also developed and incorporated into the proposed models. The proposed PF model retaining nonlinearity has a better convergence feature and requires less CPU time compared to traditional PF models. The Hessian matrices in the ...
