摘要
交直流混合的配电网络为分布式电源及新型负荷的广泛接入提供条件,是未来配电网形态的重要发展方向。本文考虑分布式光伏、风电、电化学储能、交直流负荷的接入,考虑电力电子变压器、直流变压器、故障电流限制器等电力电子设备的应用,建立交直流混合的配用电测试系统,并依据设备的控制模式,给出系统典型的运行方式。所建立的测试系统具有一定适用性,可为交直流混合的配用电系统的稳态计算和相关研究提供基础。
This paper describes a hybrid AC/DC distribution system for power flow calculation and generalized steady state research. It deals with medium and low AC/DC voltage levels. Power electronic transformers(PET), voltage source ac-dc converter and DC-DC converters are included to constitute a hybrid connected AC-DC distribution network. Distribution resources including battery energy storage system(BES), photovoltaic(PV) generation and wind turbine(WT) generation are modeled and integrated in the test system. The paper contains all the data needed to perform power flow calculation. The paper provides a basis for the steady state researches of hybrid AC/DC distribution network.
