Quasi Direct Current Optimal Power Flow Based on Modified Semi-Definite Programming Algorithm
摘要
Abstract
The quasi direct current optimal power flow (QDCOPF) model can linearize the complex nonlinear programming problem, its mathematical model structure is simple. With this model the OPF problem is solved faster but with low accuracy. Based on this situation, this paper proposed a QDCOPF based on modified semi-definite programming (MSDP) algorithm. On one hand, this algorithm adopts the SDP to solve QDCOPF model, utilizing the strong robustness nature of SDP, insensitive to initial value and able to converge to the global optimal solution. On the other hand, this algorithm optimizes the variables of SDP model, it makes up the mathematically related variables into a group and then forms a sub-block. This improved method strengthens the contact of the internal variables in a sub-block, while reducing the coupling between the variables in different sub-blocks. Finally, it follows from the simulation results of IEEE 30-bus, 118-bus and 300-bus test systems that the proposed method has higher accuracy and computational efficiency than traditional algorithm. This algorithm is proved successful and efficient.关键词
