摘　　要：分布式电源接入系统会对配电网线损产生重要影响,随着分布式电源并网发电规模化发展,合理分摊配电网线损成为当前需要解决的重要问题之一。构建了一种基于节点因子定价的含分布式电源并网的配电网线损分摊模型,通过交易盈余来弥补线损成本,在电力用户间分摊剩余费用,从而降低边际损失,通过对某区域配电网的模拟仿真验证了本文所提出方法的合理性和可行性。The integration of distributed generation into distribution network has great impact on the loss allocations of the network system. With the large-scale development of grid-connected distributed generation, the reasonable loss allocation has become an important problem to be addressed. In this paper, a loss allocation model in distribution network with distributed generation is established based on nodal price. The nodal price is to make up for loss cost by merchandise surplus, which allocates residual expenses so as to reduce the marginal loss. The simulation results of a regional distribution network show that the proposed method is reasonable and feasible.
