| Abstract: |
| Considering the impact of extreme conditions such as natural disasters and severe weather in Northeast China, the risk operation characteristics of electricity-gas-heat heterogeneous energy system are studied. The flexible resources in the domain are excavated, which participates in heterogeneous energy flow interaction. A risk defense system is proposed, including risk definition on the source-load side, identification of weak links on the grid side, and supply guarantee strategy for risk. A flexible collaborative layered model is established to analyze and regulate the risk operation of the system from four levels: evaluation, defense, stability and economy. The simulation of a heterogeneous energy system in a certain region of Nor-theast China is carried out, and a variety of collaborative defense schemes for risk scenarios are studied. The risk defense system is used to analyze the risk response resilience and flexible collaborative ability of the system. The results show that the risk defense system can effectively realize the situation awareness and differentiated governance of risk, and the low-carbon unit can further balance the supply-demand relationship of the system, which verifies that the flexible collaboration based on risk defense can effectively reduce the impact of extreme conditions on the system. |
