满足电动汽车充电需求的台区柔性资源分布式协调控制
Distributed Coordination Control of Regional Flexible Resources Based on Electric Vehicle Charging Demand
With the rapid development of the electric vehicle industry, the economic and stable operation of the AC/DC hybrid microgrid has become an important research goal. It is necessary to study the electric vehicle charging demand control technology that satisfies the island operation. Focusing on the charging demand of several electric vehicles, this paper proposes a demand-based distributed resource coordination strategy (DDRCS), based on the voltage droop control structure, an improved interconnected converter (IC) is proposed. A distributed control electric vehicle storage controller is proposed, and an AC/DC hybrid microgrid model based on regional electric vehicle charging requirements is established. The two controllers are tested under variable PV, commercial load and various faults. Performance. The example shows that the proposed distributed controller is superior to the existing distributed controller in time delay and fault conditions, which can improve the safe and economic operation capability of AC/DC hybrid microgrid under variable power generation, and can meet multiple electric vehicles. Charging needs.
