摘要/Abstract

摘要：

合理疏导高比例新能源接入下电网输配电成本是推进新型电力系统建设的重要环节。针对高比例新能源接入催生的输配电成本分摊疏导问题,提出了面向系统接网成本和强化成本的多主体划责分摊模型。首先,对于接网成本,考虑到新能源企业成本承担能力存在差异,以企业异质性为特征聚类甄别得到新能源企业集群后,基于新能源企业集群内部成本责任度量分摊接网成本。其次,对于强化成本,基于强化成本效益核算源网侧电网强化成本,分析新能源并网风险因素,考虑强化成本的共享属性构建新能源企业聚合体-联盟聚合体双层成本分摊结构,并引入风险因子量化新能源并网风险对强化成本的影响程度,进而采用不可分成本衡量新能源并网风险,提出基于EANS-Owen值的强化成本分摊模型。最后,通过算例验证了所提模型能公平合理疏导输配电成本,为面向新型电力系统的电网投资规划提供理论支撑。

Abstract:

The rational allocation of transmission and distribution costs for power grids with high renewables is an important problem to promote the construction of new-type power system. In this paper, a multi-stakeholder allocation model oriented to connection cost and reinforcement cost is proposed for the problem of transmission and distribution costs allocation bought by high renewables integration. For the connection cost, considering the difference in the cost-bearing capacity of renewables, renewable energy enterprise clusters are obtained based on heterogeneity, and hence connection cost is allocated based on cost responsibility measurement in the enterprise clusters. For the reinforcement cost, it’s divided between renewables and grid based on the cost-benefit, and the risks of renewable grid-connection are analyzed. Then, due to the shared attributes of reinforcement cost, a dual-layer cost allocation framework for renewable energy enterprise aggregation-alliance aggregation is constructed. Furthermore, the risk factors are introduced to quantify the impact of grid-connection risks on the reinforcement cost, and a nonseparable cost is regarded as a measure of renewable energy grid-connection risk. Consequently, a reinforcement cost allocation model based on EANS-Owen value is proposed. Finally, examples are given to verify that the proposed model can reasonably divert the transmission and provide theoretical support for power grid investment planning for new power systems.

Key words: transmission and distribution costs, renewable energy, cost allocation, Owen value, power grid investment planning
