In this paper, the tradable green certificate (TGC) system was introduced into the day-ahead scheduling plan of power system with wind power. Based on renewable portfolio standard (RPS), it was assumed that there was TGC trading between the power side and the grid side. Taking the maximum net revenue of both sides as the objective function, an economic dispatch model of power system with wind power was constructed. The model was solved by adaptive immune vaccine algorithm. The results indicate that the proportion of renewable energy quota and TGC price have a certain impact on the production of TGC and bilateral net revenue in the day-ahead scheduling plan.

Aiming at multi-disturbance characteristic of drum water level system, control system uses three impulse cascade control strategy. This paper designs three impulse cascade control combined of incomplete differential PID and immune P control, fully using the advantages of artificial immune feedback control and incomplete differential PID. Boiler drum level simulation result shows the cascade control based on immune feedback mechanism, can improve the system dynamic performance. The simulation results also prove the validity of the control strategy.
