Aiming at the problem that abandoning wind is still prominent because of the insufficient peak load regulation capacity of wind turbine

the effect of thermal inertia of the system on the control of co-generation unit is analyzed. It is considered that the follow-up of generation load response of conventional control system of co-generation unit is delayed for a long time

which cannot meet the requirements of fast response and cannot participate in peak load regulation in real time

so an improved control scheme is proposed to solve this problem. Through the Matlab/Stateflow simulation software

the results show that the improved control scheme is significantly better than the conventional control scheme

the response of power load response index is fast and the follow-up performance is good

which provides the preconditions for co-generation units to participate in grid peak load regulation
