Abstract: Taking a wind-solar-thermal bundled power generation system as a research object, the full use of wind power as research background, the minimum unit power generation cost of the interconnected systems as a goal, the normal operation of the system as a constraint, and the optimization of output of the wind-solar-thermal power station as a way, an optimal control strategy based on simulated annealing algorithm is proposed in this paper. Simulation results show that, under permissible conditions, the proposed optimal control strategy can effectively reduce the unit power generation cost of the interconnected power generation systems.

Key words: wind-CSP generation, output power of CSP, output power of wind power, coordinated control, unit power generation cost
