摘要：

随着分布式发电市场化进程逐步推进,按照用户接入电压等级统一核算过网费的定价方法出现难以准确区分产消者对电网资产利用程度的问题.为此,提出一种适应分布式发电市场化交易的过网费计算方法.从产消者角度分别探讨分布式发电市场点对点(P2P)交易模式和社区(CB)交易模式特征,构建P2P模式和CB模式的电能交易模型.利用基于二阶锥松弛的最优潮流模型,确定配电网潮流分布情况.借助对偶乘子的经济学意义,计算出各节点配网节点电价.考虑对偶乘子的传递性,利用耦合电能交易模型和最优潮流模型分别建立两种交易模式下的过网费计算模型.针对目前CB交易模式过网费分摊方法的局限性,采用夏普利值法将过网费按边际贡献进行公平分摊.利用改进的IEEE15节点、IEEE123节点测试系统验证所提分布式发电市场过网费计算方法的有效性和可行性.

Abstract:

With the gradual advancement of the market-oriented process of distributed generation, it is difficult to accurately distinguish the use degree of power grid assets by prosumers via pricing method of uniform calculation of network usage charge according to user access voltage. Therefore, this paper proposes a calculation method of network usage charge suitable for market-oriented trading of distributed generation. The characteristics of the peer-to-peer (P2P) trading model and the community-based (CB) trading model in distributed generation market are discussed from the perspective of prosumers. Meanwhile, the power trading models of the P2P model and the CB model are constructed. The optimal power flow model based on second-order cone relaxation is used to determine the distribution of power flow in distribution network, and the distribution locational marginal price is calculated with the economic significance of dual multiplier. Considering the transitivity of dual multipliers, calculation models of the network usage charge of the P2P trading model and the CB trading model are established by coupling the power trading model and the optimal power flow model. The limitations of the CB trading model are analyzed, and the Shapley value method is used to realize the fair allocation of network usage charge according to marginal contribution. By using the improved IEEE15 bus and IEEE123 bus test systems, the availability and feasibility of the proposed calculation method of network usage charge in distributed generation market are verified.

Key words: distributed generation, trading model, distribution locational marginal price (DLMP), network usage charge, Shapley value
