摘要：
Traditionally, wind power and solar photovoltaic (PV) power generation is non-dispatchable and their normal operation relies on Maximum Power Point Tracking (MPPT) control. Therefore, it can be of highly disturbance to the system dispatch in particularly context of microgrids. To effectively fulfill dispatch command or market schedule, a novel cascading power sharing control (PSC) scheme is proposed to coordinate wind and solar PV power productions in microgrids while reducing the loss of renewable energy production involved. Considering different properties of wind and solar PV power generation systems, the discrepancies between dispatch command (market schedule) and actual renewable generation is firstly counterbalanced by adjusting wind power output via temperately storing or releasing kinetic energy of turbine rotors. Only when rotors of wind generator reach their limitations, should solar PVs begin to reduce their generation. The proposed PSC scheme is fully simulated in a microgrid with wind and solar PV, and the simulation results clearly indicate it can be more energy efficient than the traditional dispatch method while fulfilling the dispatch demand.

摘要：
In this paper, a square root extended set membership (SRESM) state estimation algorithm is proposed to further improve the numerical accuracy and stability of the nonlinear system estimation. In comparison with the existing extended set membership (ESM), the proposed square root ESM using the efficient and stable updating recursions provides much more accurate estimation results. It has improved numerical stability and real time applicability. Simulation results in estimation of mobile robot localization are given to show the effectiveness and robustness of the proposed algorithm.

摘要：
In this paper, we present a fuzzy set membership (FSM) filter for state estimation of nonlinear discrete-time systems with unknown but bounded disturbances. First, the Takagi-Sugeno (TS) fuzzy model is used to represent the nonlinear systems. Based on this model, FSM filter is proposed to further improve the numerical accuracy and stability of the nonlinear system estimation. In comparison with the existing fuzzy Kalman (FK) filter, the proposed FSM filter using the efficient and stable updating recursions provides much more accurate estimation results. Simulation results show that the proposed algorithm can improve the performance (accuracy and reliability) of the state estimation in mobile robot localization.
