Optimization of base operation points of MTDC grid for improving transition smooth

A new approach to determine the operating point of multiterminal dc (MTDC) network for improving transition smooth, based on an optimal power flow OPF model. Aim of the method is to reduce transition distance of MTDC network. Therefore, in the proposed method, distance between the BOPs of a system at different load level ratios is deployed as an objective function. Operating points are being determined by the output of the OPF model we proposed in this paper. The proposed method is programmed in MATLAB and implemented on an eight-bus test power system. Compared to previous works, results show the validity of proposed approach and ability to improve the transition smooth in a MTDC network.
