Outline
The Three-North region in China is rich in wind and PV resources. However, the system flexibility is insufficient due to the operation constraint of “fixing power based on heat” on the combined heat and power unit, which leads to the phenomenon of wind power abandonment especially in the winter heating period. To fully exploit the system flexibility and improve the consumption level of wind power, an optimal scheduling model for an integrated energy system with operation flexibility is proposed. First, according to the physical characteristics of different types of power supply, the indices that quantify the flexibility are introduced by combing factors such as load, volatility and randomness, and a supply and demand balance model for flexibility is also established. Then, the flexibility coupling mechanism on both sides of source and load is analyzed, and the space of wind power consumption after the system flexibility is improved is quantified. On this basis, the influence of different new energy penetration rates on the system flexibility is considered. Finally, the result of a simulation example proves that the proposed scheduling model can coordinate with the flexibility resources on both sides of source and load to achieve mutual gain, which verifies its feasibility in improving the flexibility.
