The concept of Units and Grid Coordination (UGC) is introduced. Problems about UGC are drawn from some power interruptions. Some attentive issues are present in excitation selection and design in future power system such as reliable operation of PSS, coordination between excitation limiters and protections, operation mode of excitation control in running stage. Special attention should be paid to the selection of excitation type, parameters design of 1000MW class generator unit in planning stage.

Synchronous Generator Excitation

To solve synchronous generator oscillations in marine power systems which cannot be effectively suppressed, according to the nonlinearity and time variability of the ship power system, a method of synchronous generator excitation control for a ship based on active disturbance rejection control (ADRC) is proposed. Under different working conditions, three methods are automatic voltage regulator (AVR), automatic voltage regulator with power system stabilizer (PSS), and ADRC methods, which are applied to the two-generator parallel-running excitation system of a ship in simulations. The simulation results show that the excitation control system based on ADRC is faster and has better anti-interference ability and has a better restraining effect on synchronous generator oscillation.

The PV and wind hybrid power system uses the front-end DC-DC conversion circuit, the system's overall output power is unified deployment and controlled, through elaborating the component characteristics and assessing mathematical model of the actual obtained, more accurately determines operation condition of the system per hour. The system energy analysis of flow and motion makes the system in dynamic change switch from the different forms of work patterns and operation, completing the corresponding control, so as to realize the optimization of system and reliable operation.
