Study on Optimal Operation of AC-DC Hybrid Distribution Network

With the increase of power load and access distributed generation, AC/DC hybrid distribution network will become development trend urban in future. The core generation are voltage source converters based on full control switches. This paper simply analyzes operation principle mode converters, a flow calculation method system is proposed, optimization model with minimum loss deviation DC established. particle swarm (PSO) algorithm used to solve calculation. Considering disturbance, droop set for each VSC, at same time this compares advantages disadvantages whole optimal combined method. Then proposed. Finally, an example PG&E 69-node United States given verify correctness proposed algorithm.
