Embodiment 1
[0093] The present invention provides an emergency response method for extreme events in complex energy interconnection systems, such as figure 1 shown, including the following steps:
[0094] S1: Based on the power transmission-gas network, connect the regional comprehensive energy system and build a complex energy interconnection system structure.
[0095] Such as figure 2 As shown, the complex energy interconnection system is centered on multi-energy interconnection and complementarity, including two levels of transmission network and distribution network. According to the decision-making subject and function, it can be divided into multiple subsystems, and each subsystem operates according to its own decision-making rules. The transmission network layer is composed of a large-capacity transmission network subsystem and a gas transmission network subsystem. The gas-fired power plant is used as a bridge to connect and is responsible for the long-distance transmission of en...
Embodiment 2
[0175] This embodiment is an example analysis:
[0176] (1) Calculation parameters
[0177] In this calculation example, the IEEE 30-node transmission network modified in MATPOWER is coupled with the Belgian 20-node natural gas grid through gas-fired power plants as the energy backbone Internet, which connects seven regional comprehensive energy hubs H1-H7 downward; the Belgian 20-node gas transmission network is as follows: Figure 7 As shown, it contains 20 nodes, 19 gas pipelines (17 passive pipelines and 2 active pipelines with compressors), and 6 gas source points S 1 ~S 6 , two gas-fired power plants G 1 , G 2 ; The modified IEEE30 node transmission network in MATPOWER is as follows Figure 8 As shown, the IEEE30 node transmission network includes 41 transmission lines, 11 power plants (4 coal-fired power plants C1-C4, 2 gas-fired power plants G1-G2, 5 wind farms W1-W5), and 2 gas-fired power plants They are respectively located at nodes 1 and 22, and are interconne...
