Abstract: A method and device for supporting weak networks in an AC/DC distribution network are provided. The method includes the following steps: constructing a topology of the AC/DC distribution network, where the topology is configured to support the weak networks and isolate faults actively, and the topology is a multi-terminal ring structure; establishing a distributed optimization method for the AC/DC distribution network based on the topology; obtaining power fluctuations of the AC/DC distribution network, where the AC/DC distribution network can switch a droop control mode automatically according to the power fluctuations; and obtaining frequency fluctuations of the AC/DC distribution network, where the AC/DC distribution network performs energy dispatching according to the frequency fluctuations to match the droop control mode of the AC/DC distribution network.

Abstract: An ionic liquid solvent and gas purification method using the same are provided. The ionic liquid solvent consists of a main absorbent, a regulator for the main absorbent, an auxiliary absorbent, an activator, an antioxidant and water. The ionic liquid involves a low synthetic cost, low viscosity and high absorption capacity, and can be easily regenerated and recycled. The method, compared with traditional processes, has advantages such as a greater absorption capability and lower operation cost.
