摘  要:
将不同类型分布式发电的潮流计算模型划分为3种,即PQ型、PV型和PQ(V)型。基于恒功率负荷模型,采用以功率为变量的前推回代算法,研究不同类型DG在农村配电网中接入位置和容量不同对系统电压分布和网损影响的变化规律,通过IEEE 33节点系统对不同类型DG接入辐射状农村配电网前后的电压分布和网损进行详细的仿真计算。结果表明:优化配置分布式电源类型、接入位置和容量能够改善农村配电网电压分布和有效减少网损。

摘  要:
A power flow algorithm was presented based on constant power load model in backward/forward sweep technique which uses active and reactive power as flow variables. The mathematical model of different types of distributed generation(DG) is modeled as PQ, PV and PQ(V) buses in the power flow program. Based on the proposed algorithm, the voltage profile and active power losses were calculated corresponding to DG units in different modes for radial rural power distribution networks. IEEE 33-bus test system was analyzed. The simulation results showed the change law of voltage and active power losses when locations and output of different DG changed. The rational distribution of the types, location and capacity of DG can effectively improve the voltage and reduce the power losses.
