摘要
随着以光伏为代表的分布式能源(DER)广泛开发利用,其对配电网的扰动、补贴缺口等问题使得局部区域内用户间分布式电能的共享模式得到普遍应用。文中从整体角度分析了共享模式下配电公司、共享协调管理员、分布式光伏拥有者和分享者等各相关参与主体的利益问题,搭建了包括分布式光伏电能共享模块、配电公司收益和输配电价等耦合模块的系统动力学模型,模拟仿真了不同分布式光伏安装率和上网电价下的共享价值变化,并就其对配电公司利益和输配电价的影响进行了前瞻性分析。算例分析结果表明,共享价值空间随区域内的分布式光伏安装率变化而存在一个峰值,因此合理规划区域内分布式光伏接入有利于各参与主体调整策略,促进多方收益协调。
With the extensive development and utilization of distributed energy resource(DER) represented by photovoltaics, its disturbance to distribution networks, subsidy gap and other problems lead to the widespread application of the distributed energy sharing mode among users in local areas. In this paper, the interest problem of various related participants is analyzed from the overall perspective, including the distribution companies, sharing coordinators, distributed photovoltaic owners and sharers in shared mode, and a system dynamics model for coupling modules is built, including the distributed photovoltaic power sharing module, distribution grid company revenue module, and transmission and distribution tariff module. The changes in sharing value with different distributed photovoltaic installation ratios and feed-in tariffs are simulated, and a forward-looking analysis of its impact on the distribution company interest and the transmission and distribution tariff is conducted. The case analysis results show that there is a peak of sharing value with the change of distributed photovoltaic installation ratios in a local area. Therefore, the reasonable planning of the distributed photovoltaic access level in a local area is conducive to the strategic adjustment of each participant and the promotion of the coordination of multi-participants’ benefits.
