This paper proposes a coordination control strategy of voltage source converter based multi-terminal DC (VSC-MTDC) transmission system for integrating large-scale offshore wind power. Using a typical five-terminal DC transmission system as an example, coordination control strategy based on local controller among converter stations is proposed. Based on the DC voltage-active power characteristic, improved control strategy for auxiliary converter station and APC converter station are proposed respectively. Also the working mode of the two converter stations is analyzed. The basis of parameter selection of auxiliary converter station and APC converter station is presented due to DC power flow distribution and maximum and minimum operational mode. Finally, simulations in PSCAD/EMTDC are conducted to validate the multi-point DC voltage control method under various operating state in normal, master converter station fault and auxiliary converter station fault conditions respectively. Results show that this method can guarantee the active power allocation of VSC-MTDC transmission system and good control effects are obtained.

The multipath estimation of global navigation satellite system (GNSS) signal is actually the state estimation of nonlinear/non-Gaussian systems. The extension of sliced Gaussian mixture filter (ESGMF) based on Gaussian sum approximation is proposed for the state estimation of nonlinear/non-Gaussian state space, and the probability density function (PDF) expression of states is derived recursively for a time varying system. Resampling is applied to the prediction PDF to reduce the complexity of Bayesian inference. The simulation result of multipath estimation with ESGMF shows that the ESGMF algorithm performs better in accuracy than the algorithms based on particle filter (PF) and extended Kalman filter (EKF).
