A mathematic model of battery energy storage system (BESS) and integrated load model are built, and a multi-index nonlinear coordinated control scheme for the system is proposed. As a new FACTS facility, BESS can regulate active power and reactive power of the power bus synchronously. Simulation results show that BESS has the advantage of availably reducing the influence of the power bus subjected to a disturbance on load voltage and active power. It can enhance the control accuracy of output variables and voltage stability, improve the power quality of load. With the ability of BESS, the dynamic characteristics of load voltage and active power can be controlled more smoothness, and the responses of the system is more speediness.

A multi-index nonlinear coordinated control scheme for BESS and generator excitation is proposed. The proposed multi-index nonlinear coordinated controller can effectively coordinate the dynamic and steady-state performance of the controlled system. It can enhance the stability of the system, improve the dynamic characteristics of state variables, and can improve the control accuracy of output variables such as terminal voltage, active power output of the generator. Simulation results show that to control BESS and generator coordinately has the advantage of enhancing the stability of the system. With the ability of BESS to control the active power and reactive power, and coordinating generator excitation regulate, the dynamic characteristics of state variables can changes more smoothness, and the responds are more speedily.

This paper puts forward a complete track forecasting models, using Kalman filter to track and predict the movement of objects without prior knowledge. Use the extracted Harris corner to calculate optical flow between two frames by L-K pyramid method, getting the convex hull of moving objects by optical flow clustering to separate the moving objects from background. Tracking and predicting the gravity of moving objects convex hull can solve the occlusion and separation problem between moving objects. Computer simulation and field test results show that the proposed method has higher tracking accuracy, and small amount of calculation.
