Abstract

With the full integration of wind and solar renewable energy

the increase of the total amount of wind and solar energy and the problem of insufficient system power regulation margin are becoming more and more serious.In order to realize the economic utilization of renewable energy and the stable operation of energy system

it is urgent to solve these problems

this paper proposes a bi- level optimal scheduling strategy for power margin adjustment of wind- solar- thermal- ammonia combined system considering ammonia waste heat recovery. Firstly

the overall power regulation margin model of thermal power unit- ammonia energy system and its waste heat recovery is established. Then

considering the influence of ambient temperature on the waste heat recovery efficiency of ammonia energy system

a bi- level optimal scheduling model is constructed with the maximum power regulation margin of wind- solar- fire- ammonia combined system as the upper objective and the minimum total cost as the lower objective.Finally

the simulation results show that the proposed optimal scheduling method can improve the power regulation margin of the combined system and promote the consumption of renewable energy.
