Optimal Dispatching of Integrated Energy System in Industrial Parks Considering Wind and Solar Uncertainty and Flexibility Indicators
In view of the lack of flexibility in the dispatching process of the park integrated energy system with high wind and solar penetration rate,the author proposes a day-ahead dispatching strategy for park level integrated energy system considering wind and solar uncertainty and power flexibility indicators.In the dispatching model,the opportunity constraint theory is used to provide backup services for the uncertainty of wind and solar power,and the power-type flexibility index is used to quantitatively evaluate the flexibility supply.On this basis,a day-ahead optimized dispatching model that takes into account economic cost and flexibility supply is constructed,and is solved by mixed integer programming.The simulation results show that the scheduling strategy effectively ensures the flexibility and economy of system operation.
